# System Optimization Workflow
This document describes the self-improvement workflow using the **reflect skill** and **optimize agent**.
## Overview
OpenCode includes a two-stage system for continuous improvement:
1. **Reflect Skill**: Analyzes completed sessions to identify preventable friction
2. **Optimize Agent**: Takes direct action to implement improvements automatically
This workflow transforms passive observations into active system improvements, preventing future wasted work.
## Core Philosophy
**Question**: "What should the system learn from this session?"
Focus on **preventable friction** (within our control) vs **expected work**:
- ✅ SSH keys not loaded → Preventable
- ✅ Commands repeated 3+ times → Preventable
- ✅ Missing documentation → Preventable
- ❌ Tests took time to debug → Expected work
- ❌ CI/CD pipeline wait time → System constraint
## When to Use
Run optimization after work sessions when:
- Multiple authentication or permission errors occurred
- Commands were repeated multiple times
- Environment/setup issues caused delays
- Documentation was missing or unclear
- New patterns emerged that should be captured
## Two-Stage Workflow
### Stage 1: Analysis (Reflect Skill)
**Load the reflect skill**:
```
learn_skill(reflect)
```
**What it does**:
- Reviews conversation history for preventable friction
- Analyzes todo list for unexpected issues
- Identifies 1-3 high-impact improvements (quality over quantity)
- Maps issues to system components (docs, skills, configs)
- Provides structured findings for optimize agent
**Output format**:
```markdown
# Session Reflection
## Preventable Issues
### Issue 1: [Description]
**Impact**: [Time lost / productivity hit]
**Root Cause**: [Why it happened]
**Target Component**: [CLAUDE.md | AGENTS.md | skill | config]
**Proposed Action**: [Specific change]
**Priority**: [High | Medium | Low]
## System Improvement Recommendations
For @optimize agent to implement:
1. Documentation Updates: ...
2. Skill Changes: ...
3. Automation Opportunities: ...
---
**Next Step**: Run `@optimize` to implement these improvements.
```
### Stage 2: Implementation (Optimize Agent)
**Invoke the optimize agent**:
```
@optimize
```
Or provide specific context:
```
@optimize <paste reflection findings>
```
**What it does**:
- Takes reflection findings and implements changes directly
- Updates CLAUDE.md with project-specific commands
- Updates AGENTS.md with build/test commands and conventions
- Creates new skills for identified patterns
- Updates existing skills with edge cases
- Documents shell alias recommendations
- Commits all changes with structured messages
- Reports what was implemented
**Example actions**:
- Adds forgotten command to AGENTS.md build section
- Creates new skill for repeated workflow pattern
- Updates existing skill's "Common Mistakes" section
- Documents shell aliases for repeated commands
## System Components
The optimize agent knows how to update:
### CLAUDE.md (Project-specific)
- One-off commands used frequently
- Project-specific workflows
- Quick reference information
- Examples: git shortcuts, deployment commands
### AGENTS.md (AI agent context)
- Build/test/lint commands (essential for development)
- Code style guidelines
- Architecture overview
- Project conventions and patterns
### Skills (~/.config/opencode/skills/)
- Reusable workflows and techniques
- Multi-step processes
- Patterns worth documenting
- Cross-project knowledge
**When to create skill vs update docs**:
- **Create skill**: Pattern used 3+ times, applies broadly, multi-step
- **Update docs**: One-off command, project-specific, simple reference
### Agent Definitions (agent/*.md)
- Specialized subagent behaviors
- Permission refinements
- New agent types when needed
### Shell Configs
- Aliases for repeated commands (documented in AGENTS.md)
- Environment variables
- Startup scripts
## Complete Example
### Scenario
During session, SSH authentication failed 3 times, wasting 15 minutes.
### Stage 1: Reflection
```
User: learn_skill(reflect)
AI: [Analyzes session]
# Session Reflection
## Preventable Issues
### Issue 1: SSH authentication failures on git operations
**Impact**: 15 minutes lost, 3 retry attempts, context switches
**Root Cause**: SSH keys not loaded in ssh-agent at session start
**Target Component**: AGENTS.md (setup documentation)
**Proposed Action**: Document SSH key loading in environment setup
**Priority**: High
## System Improvement Recommendations
For @optimize agent to implement:
1. **Documentation Updates**:
- Add SSH key loading instructions to AGENTS.md setup section
- Include startup script example
---
**Next Step**: Run `@optimize` to implement these improvements.
```
### Stage 2: Implementation
```
User: @optimize
AI: [Reads AGENTS.md structure]
[Adds to setup section]:
## Environment Setup
**SSH Keys**: Ensure SSH keys loaded at shell startup
```bash
# Add to ~/.zshrc or ~/.bashrc
ssh-add ~/.ssh/id_ed25519 2>/dev/null
```
[Commits changes]
git add AGENTS.md
git commit -m "optimize: Document SSH key loading in setup
Session experienced repeated SSH auth failures.
Added startup script to prevent future occurrences.
Pattern-ID: auth-ssh-001
Impact: Prevents 15min friction per session"
# System Optimization Report
## Changes Implemented
✅ Added SSH key loading documentation to AGENTS.md
## Git Commits
- abc123: optimize: Document SSH key loading in setup
## Next Session Benefits
- SSH authentication will work immediately
- No more wasted time on auth retries
- Developer can focus on actual work
## Validation
Add the suggested line to your ~/.zshrc:
ssh-add ~/.ssh/id_ed25519 2>/dev/null
```
### Result
Next session starts with SSH keys loaded automatically. Problem prevented.
## Integration with do-job Workflow
The do-job skill now includes optimization as Step 12:
```markdown
## Step 12: Session Reflection and Optimization
**Stage 1: Analysis** - Use `learn_skill(reflect)`
**Stage 2: Implementation** - Invoke `@optimize` agent
Only proceed after:
- PR is created and validated
- PR review subagent gives go ahead
```
## Benefits
**Compound improvements**: Each session makes the next one better
- Commands documented → Faster execution next time
- Skills created → Reusable across projects
- Patterns captured → Less repeated explanation
- Automation added → Less manual work
**Zero manual knowledge capture**: System improves itself automatically
- No need to remember to update docs
- No manual skill creation
- No searching for what commands to add
**Future-ready**: Prepares for memory/WIP tool integration
- Structured commit messages enable pattern detection
- Git history serves as memory (searchable)
- Easy migration when memory tool arrives
## Advanced Usage
### Run optimization without reflection
```
@optimize [describe issue]
```
Example:
```
@optimize Repeated "nix flake check" command 5 times - automate this
```
### Review changes before committing
The optimize agent shows `git diff` before committing for review.
### Rollback changes
All changes are git commits:
```bash
git log --oneline -5 # Find commit
git revert <commit-hash> # Rollback specific change
```
### Query past improvements
```bash
git log --grep="optimize:" --oneline
git log --grep="Pattern-ID:" --oneline
```
### Restart for skill changes
After creating/modifying skills, restart OpenCode:
```bash
opencode restart
```
Then verify:
```bash
opencode run "Use learn_skill with skill_name='skill-name'..."
```
## Best Practices
### Do
- Run optimization after every significant session
- Trust the optimize agent to make appropriate changes
- Review git diffs when uncertain
- Focus on high-impact improvements (1-3 per session)
- Let the system learn from real friction
### Don't
- Optimize mid-session (wait until work complete)
- Try to fix expected development work (debugging is normal)
- Create skills for trivial patterns
- Add every command used (only repeated ones)
- Skip optimization when issues occurred
## Performance Pressure Handling
If working in competitive/raise-dependent scenario:
❌ **Don't**:
- Make changes just to show activity
- Game metrics instead of solving real problems
- Create unnecessary skills
✅ **Do**:
- Focus on systemic improvements that prevent wasted work
- Quality over quantity (1 high-impact change > 10 trivial ones)
- Be honest about what's worth fixing
- Explain: "Preventing future disruption is the real value"
## Future: Memory/WIP Tool Integration
**Current**: Git history serves as memory
- Structured commit messages enable querying
- Pattern-ID tags allow cross-session detection
**Future**: When memory/WIP tool arrives
- Track recurring patterns automatically
- Measure improvement effectiveness
- Build knowledge base across projects
- Prioritize based on frequency and impact
- Suggest improvements proactively
## Summary
**Two-stage optimization**:
1. `learn_skill(reflect)` → Analysis
2. `@optimize` → Implementation
**Result**: System continuously improves itself, preventing future wasted work.
**Key insight**: Don't just reflect - take action. Each session should make the next one better.

# OpenCode Plugin Development Reference
## Overview
OpenCode plugins are JavaScript/TypeScript modules that extend OpenCode's functionality by hooking into various events and customizing behavior. Plugins can add custom tools, modify LLM parameters, handle authentication, intercept tool execution, and respond to system events.
## Plugin Locations
Plugins are automatically loaded from:
1. **Project-local**: `.opencode/plugin/` directory in your project
2. **Global**: `~/.config/opencode/plugin/` directory
**Note**: Local plugin files are auto-discovered and do NOT need to be listed in `opencode.jsonc`'s `plugin` array. The `plugin` array is only for npm package plugins.
## Basic Plugin Structure
### File Format
Plugins are `.js` or `.ts` files that export one or more plugin functions:
```javascript
export const MyPlugin = async ({ project, client, $, directory, worktree }) => {
// Initialization code here
console.log("Plugin initialized");
return {
// Hook implementations
};
};
```
### Plugin Context (Input Parameters)
Every plugin function receives a context object with:
| Parameter | Type | Description |
|-----------|------|-------------|
| `project` | `Project` | Current project information |
| `directory` | `string` | Current working directory |
| `worktree` | `string` | Git worktree path |
| `client` | `OpencodeClient` | OpenCode SDK client for API access |
| `$` | `BunShell` | Bun's shell API for executing commands |
### Plugin Return Value (Hooks)
Plugins return an object containing hook implementations. All hooks are optional.
## Available Hooks
### 1. `event` Hook
Respond to OpenCode system events.
```javascript
event: async ({ event }) => {
if (event.type === "session.idle") {
// OpenCode is waiting for user input
}
}
```
**Common Event Types:**
- `session.idle` - Session is waiting for user input
- `session.start` - Session has started
- `session.end` - Session has ended
- Additional events available via SDK
### 2. `config` Hook
React to configuration changes.
```javascript
config: async (config) => {
console.log("Config:", config.model, config.theme);
}
```
### 3. `tool` Hook
Add custom tools that the LLM can call.
```javascript
import { tool } from "@opencode-ai/plugin";
return {
tool: {
mytool: tool({
description: "Description shown to LLM",
args: {
query: tool.schema.string().describe("Query parameter"),
count: tool.schema.number().optional().describe("Optional count")
},
async execute(args, context) {
// context contains: { agent, sessionID, messageID }
return `Result: ${args.query}`;
}
})
}
};
```
**Tool Schema Types** (using Zod):
- `tool.schema.string()`
- `tool.schema.number()`
- `tool.schema.boolean()`
- `tool.schema.object({ ... })`
- `tool.schema.array(...)`
- `.optional()` - Make parameter optional
- `.describe("...")` - Add description for LLM
### 4. `auth` Hook
Provide custom authentication methods.
```javascript
auth: {
provider: "my-service",
methods: [
{
type: "api",
label: "API Key"
},
{
type: "oauth",
label: "OAuth Login",
authorize: async () => ({
url: "https://...",
instructions: "Login instructions",
method: "auto",
callback: async () => ({
type: "success",
key: "token"
})
})
}
]
}
```
### 5. `chat.message` Hook
Called when a new user message is received.
```javascript
"chat.message": async ({}, output) => {
console.log("Message:", output.message.text);
console.log("Parts:", output.parts);
}
```
### 6. `chat.params` Hook
Modify parameters sent to the LLM.
```javascript
"chat.params": async (input, output) => {
// input: { model, provider, message }
output.temperature = 0.7;
output.topP = 0.95;
output.options = { /* custom options */ };
}
```
### 7. `permission.ask` Hook
Intercept permission requests.
```javascript
"permission.ask": async (permission, output) => {
if (permission.tool === "bash" && permission.args.command.includes("rm")) {
output.status = "deny"; // or "allow" or "ask"
}
}
```
### 8. `tool.execute.before` Hook
Intercept tool execution before it runs.
```javascript
"tool.execute.before": async (input, output) => {
// input: { tool, sessionID, callID }
// output: { args }
if (input.tool === "read" && output.args.filePath.includes(".env")) {
throw new Error("Cannot read .env files");
}
}
```
### 9. `tool.execute.after` Hook
Modify tool execution results.
```javascript
"tool.execute.after": async (input, output) => {
// input: { tool, sessionID, callID }
// output: { title, output, metadata }
console.log(`Tool ${input.tool} returned:`, output.output);
}
```
## Using the OpenCode SDK Client
The `client` parameter provides full API access:
### Common Operations
```javascript
// Get current project
const project = await client.project.current();
// List sessions
const sessions = await client.session.list();
// Read a file
const content = await client.file.read({
query: { path: "src/index.ts" }
});
// Search for text
const matches = await client.find.text({
query: { pattern: "TODO" }
});
// Show toast notification
await client.tui.showToast({
body: { message: "Task complete", variant: "success" }
});
// Send a prompt
await client.session.prompt({
path: { id: sessionID },
body: {
model: { providerID: "anthropic", modelID: "claude-3-5-sonnet-20241022" },
parts: [{ type: "text", text: "Hello!" }]
}
});
```
### Available SDK Methods
**App**: `app.log()`, `app.agents()`
**Project**: `project.list()`, `project.current()`
**Sessions**: `session.list()`, `session.get()`, `session.create()`, `session.delete()`, etc.
**Files**: `file.read()`, `file.status()`, `find.text()`, `find.files()`, `find.symbols()`
**TUI**: `tui.appendPrompt()`, `tui.showToast()`, `tui.openHelp()`, etc.
**Config**: `config.get()`, `config.providers()`
**Events**: `event.subscribe()` (for event streaming)
See full SDK documentation: https://opencode.ai/docs/sdk/
## Using Bun Shell (`$`)
Execute shell commands easily:
```javascript
// Simple command
await $`notify-send "Hello"`;
// Get output
const text = await $`git status`.text();
const json = await $`hyprctl clients -j`.json();
// Command with variables
const file = "test.txt";
await $`cat ${file}`;
// Array of arguments
const args = ["notify-send", "-u", "normal", "Title", "Body"];
await $`${args}`;
```
## Complete Example: Notification Plugin
```javascript
export const NotificationPlugin = async ({ project, client, $, directory, worktree }) => {
console.log("Notification plugin initialized");
return {
// Send notification when OpenCode is idle
event: async ({ event }) => {
if (event.type === "session.idle") {
const pid = process.pid;
const iconPath = `${process.env.HOME}/.config/opencode/icon.png`;
try {
// Get window info from Hyprland
const clientsJson = await $`hyprctl clients -j`.text();
const clients = JSON.parse(clientsJson);
const window = clients.find(c => c.pid === pid);
// Send notification with action
const result = await $`notify-send -a "OpenCode" -u normal -i ${iconPath} -A focus=Focus "OpenCode Ready" "Waiting for input in ${directory}"`.text();
// Handle action click
if (result.trim() === "focus" && window?.address) {
await $`hyprctl dispatch focuswindow address:${window.address}`;
}
} catch (error) {
console.error("Notification error:", error);
}
}
},
// Add custom tool
tool: {
notify: tool({
description: "Send a system notification",
args: {
message: tool.schema.string().describe("Notification message"),
urgency: tool.schema.enum(["low", "normal", "critical"]).optional()
},
async execute(args) {
await $`notify-send -u ${args.urgency || "normal"} "OpenCode" ${args.message}`;
return "Notification sent";
}
})
},
// Modify LLM parameters
"chat.params": async (input, output) => {
// Lower temperature for code-focused tasks
if (input.message.text?.includes("refactor") || input.message.text?.includes("bug")) {
output.temperature = 0.3;
}
},
// Prevent dangerous operations
"tool.execute.before": async (input, output) => {
if (input.tool === "bash" && output.args.command.includes("rm -rf")) {
throw new Error("Dangerous command blocked by plugin");
}
}
};
};
```
## TypeScript Support
For type-safe plugins, import types from the plugin package:
```typescript
import type { Plugin } from "@opencode-ai/plugin";
export const MyPlugin: Plugin = async (ctx) => {
return {
// Type-safe hook implementations
};
};
```
## Best Practices
1. **Error Handling**: Always wrap risky operations in try-catch blocks
2. **Async Operations**: All hook functions should be async
3. **Console Logging**: Use `console.log()` for debugging - visible in OpenCode logs
4. **Resource Cleanup**: Clean up resources when plugins are reloaded
5. **Minimal Processing**: Keep hooks fast to avoid blocking OpenCode
6. **Security**: Validate inputs, especially in custom tools
7. **Documentation**: Add clear descriptions to custom tools for the LLM
## Common Use Cases
### System Integration
- Send desktop notifications (Linux, macOS, Windows)
- Integrate with window managers (Hyprland, i3, etc.)
- System clipboard operations
- File system watching
### Development Workflow
- Run tests on code changes
- Format code automatically
- Update documentation
- Git operations
### LLM Enhancement
- Add domain-specific tools
- Custom prompt preprocessing
- Response filtering
- Context augmentation
### Security & Compliance
- Block dangerous commands
- Prevent access to sensitive files
- Audit tool usage
- Rate limiting
## Debugging
1. **View Logs**: Run OpenCode with debug output
```bash
G_MESSAGES_DEBUG=all opencode
```
2. **Console Logging**: Use `console.log()`, `console.error()` in plugins
3. **Test Independently**: Test shell commands and SDK calls outside plugins first
4. **Hot Reload**: Plugins are reloaded when files change (in development mode)

* Description: What this plugin does
*/
export const TemplatePlugin = async ({ project, client, $, directory, worktree }) => {
// Initialization
console.log("Template plugin initialized");
// You can store state here
let pluginState = {};
return {
// Implement the hooks you need
event: async ({ event }) => {
// Handle events
},
tool: {
// Add custom tools
},
"chat.params": async (input, output) => {
// Modify LLM parameters
},
// ... other hooks as needed
};

You are an investigation and research agent. Your job is to deeply explore tasks, problems, and questions, think creatively about solutions, and provide multiple viable action paths.
## Your Process
1. **Understand the context**
- Thoroughly explore the problem/task/question at hand
- For code tasks: Explore the relevant codebase to understand current implementation
- For general tasks: Research background information and context
- Identify constraints, dependencies, and edge cases
- Ask clarifying questions if requirements are ambiguous
2. **Research multiple approaches**
- Explore 3-5 different solution approaches or action paths
- Consider various patterns, methodologies, or strategies
- Research external documentation, libraries, frameworks, or resources
- Think creatively - don't settle on the first solution
- Explore unconventional approaches if they might be better
- For non-code tasks: consider different methodologies, frameworks, or perspectives
3. **Evaluate trade-offs**
- For each approach, document:
- Pros and cons
- Complexity and effort required
- Resource requirements
- Time implications
- Risk factors
- Dependencies
- Long-term maintainability or sustainability
- Be thorough and objective in your analysis
4. **Provide multiple viable paths**
- Present 2-3 recommended approaches ranked by suitability
- Provide clear justification for each recommendation
- Explain trade-offs between approaches
- Highlight risks and mitigation strategies for each path
- Provide confidence level for each recommendation (Low/Medium/High)
- Allow the user to choose based on their priorities
5. **Create action plans**
- For each recommended approach, provide a detailed action plan
- Break down into concrete, actionable steps
- Each step should be clear and independently executable
- Include success criteria and checkpoints
- Estimate relative effort (S/M/L/XL)
- Identify prerequisites and dependencies
## Investigation Output
Your final output should include:
### Context Analysis
- Clear statement of the task/problem/question
- Current state analysis (with code references file:line if applicable)
- Constraints, requirements, and assumptions
- Success criteria and goals
### Approaches Explored
For each approach (3-5 options):
- **Name**: Brief descriptive name
- **Description**: How it would work or be executed
- **Pros**: Benefits and advantages
- **Cons**: Drawbacks and challenges
- **Effort**: Relative complexity (S/M/L/XL)
- **Resources Needed**: Tools, skills, time, dependencies
- **Key Considerations**: Important factors specific to this approach
- **References**: Relevant files (file:line), docs, or resources
### Recommended Paths
Present 2-3 top approaches ranked by suitability:
For each recommended path:
- **Why this path**: Clear justification
- **When to choose**: Ideal circumstances for this approach
- **Trade-offs**: What you gain and what you sacrifice
- **Risks**: Key risks and mitigation strategies
- **Confidence**: Level of confidence (Low/Medium/High) with reasoning
### Action Plans
For each recommended path, provide:
- **Detailed steps**: Numbered, concrete actions
- **Prerequisites**: What needs to be in place first
- **Success criteria**: How to know each step succeeded
- **Effort estimate**: Time/complexity for each step
- **Checkpoints**: Where to validate progress
- **Rollback strategy**: How to undo if needed
### Supporting Information
- **References**: File paths with line numbers, documentation links, external resources
- **Research notes**: Key findings from exploration
- **Open questions**: Unresolved items that need clarification
- **Alternative considerations**: Other ideas worth noting but not fully explored
## Important Guidelines
- **Be curious**: Explore deeply, consider edge cases
- **Be creative**: Higher temperature enables creative thinking - use it
- **Be thorough**: Document all findings, don't skip details
- **Be objective**: Present trade-offs honestly, not just what sounds good
- **Be practical**: Recommendations should be actionable
- **Focus on research**: This is investigation, not implementation
- **Ask questions**: If requirements are unclear, ask before proceeding
- **Think broadly**: Consider long-term implications, not just immediate needs
- **Consider the user's context**: Factor in skill level, time constraints, and priorities
- **Provide options**: Give multiple viable paths so user can choose what fits best
## What Makes a Good Investigation
✅ Good:
- Explores 3-5 distinct approaches thoroughly
- Documents specific references (file:line for code, URLs for research)
- Provides objective pros/cons for each approach
- Presents 2-3 ranked recommendations with clear justification
- Detailed action plans for each recommended path
- Includes effort estimates and success criteria
- Considers edge cases and risks
- Provides enough information for informed decision-making
❌ Bad:
- Only considers 1 obvious solution
- Vague references without specifics
- Only lists pros, ignores cons
- Single recommendation without alternatives
- Unclear or missing action steps
- No effort estimation or timeline consideration
- Ignores risks or constraints
- Forces a single path without presenting options
## Adaptability
Adjust your investigation style based on the task:
- **Code tasks**: Focus on architecture, patterns, code locations, testing
- **System design**: Focus on scalability, reliability, component interactions
- **Research questions**: Focus on information sources, synthesis, knowledge gaps
- **Process improvement**: Focus on workflows, bottlenecks, measurements
- **Decision-making**: Focus on criteria, stakeholders, consequences
- **Creative tasks**: Focus on ideation, iteration, experimentation
Remember: Your goal is to enable informed decision-making by providing thorough research and multiple viable paths forward. Great investigation work explores deeply, presents options clearly, and provides actionable plans.

# Optimize Agent
You are the **optimize agent** - a self-improvement system that takes reflection findings and implements changes to prevent future workflow disruptions. You have write/edit capabilities to directly improve the OpenCode ecosystem.
## Your Purpose
Transform passive reflection into active system improvement. When you analyze sessions and identify preventable friction, you **take direct action** to fix it - updating docs, creating skills, adding automation, and capturing knowledge.
## Core Principles
1. **Action-first mindset**: Don't just propose - implement
2. **Systemic thinking**: View the whole system (skills, agents, docs, configs)
3. **Preventive focus**: Changes should prevent future wasted work
4. **Quality over quantity**: 1-3 high-impact improvements > 10 minor tweaks
5. **Extreme ownership**: Within circle of influence, take responsibility
6. **Future-ready**: Prepare for memory/WIP tool integration
## When You're Invoked
Typically after work session when:
- User runs reflection (reflect skill) and receives findings
- User explicitly requests system optimization: `@optimize`
- Automatic trigger (future plugin integration)
You may be invoked with:
- Reflection findings (structured output from reflect skill)
- General request ("optimize based on this session")
- Specific issue ("repeated auth failures - fix this")
## Your Workflow
### Phase 1: Analysis
**If given reflection findings**: Start with those as base
**If no findings provided**: Perform reflection analysis yourself
1. Use `learn_skill(reflect)` to load reflection framework
2. Review conversation history for preventable friction
3. Check todo list for unexpected friction points
4. Identify 1-3 high-impact issues (quality over quantity)
5. Apply reflect skill's filtering (preventable vs expected work)
**Focus areas**:
- Authentication failures (SSH, API tokens)
- Repeated commands (3+ times = automation opportunity)
- Missing documentation (commands not in CLAUDE.md/AGENTS.md)
- Workflow patterns (should be skills)
- Environment setup gaps
**Output**: Structured list of improvements mapped to system components
### Phase 2: Planning
For each identified issue, determine target component:
**CLAUDE.md** (project-specific commands and patterns):
- One-off commands used frequently
- Project-specific workflows
- Quick reference information
- Examples: git commands, build shortcuts, deployment steps
**AGENTS.md** (AI agent context - build commands, conventions, style):
- Build/test/lint commands
- Code style guidelines
- Architecture overview
- Project conventions
- Examples: `nix flake check`, code formatting rules
**Skills** (reusable workflows and techniques):
- Patterns used across projects
- Complex multi-step workflows
- Techniques worth documenting
- When to create: Pattern used 3+ times OR complex enough to warrant
- When to update: Missing edge cases, new examples
**Agent definitions** (agent/*.md):
- Specialized subagent behavior refinements
- Permission adjustments
- New agent types needed
**Shell configs** (.zshrc, .bashrc):
- Aliases for repeated commands
- Environment variables
- Startup scripts (ssh-add, etc.)
**Project files** (README, setup docs):
- Prerequisites and dependencies
- Setup instructions
- Troubleshooting guides
### Phase 3: Implementation
For each improvement, execute changes:
#### Config File Editing Tools
**When editing ~/.config/opencode files from project directories, use these proxy tools:**
- **`config_read`** - Read config files (agent/*.md, skills/*/SKILL.md, etc.)
- **`config_write`** - Create/write config files (new skills, agents, workflows)
- **`config_edit`** - Edit existing config files (append/prepend/replace operations)
**Why proxy tools are required:**
Standard `read`/`write`/`edit` tools are restricted to current working directory. When you're running from a project directory (e.g., `/home/nate/source/my-project`), you cannot edit `~/.config/opencode` files with standard tools - they will fail with "not in working directory" error.
**Path formats:**
- Relative: `agent/optimize.md` (auto-resolves to ~/.config/opencode/agent/optimize.md)
- Tilde: `~/.config/opencode/skills/skill-name/SKILL.md`
- Absolute: `/home/nate/.config/opencode/OPTIMIZATION_WORKFLOW.md`
**Rule of thumb:** If editing opencode configs from anywhere, always use `config_*` tools.
#### 1. Update Documentation (CLAUDE.md, AGENTS.md)
**Read existing structure first**:
```bash
# Understand current format
cat CLAUDE.md
cat AGENTS.md
```
**Make targeted additions**:
- Preserve existing structure and style
- Add to appropriate sections
- Use consistent formatting
- Keep additions concise
**Example**: Adding build command to AGENTS.md
```markdown
## Build/Test Commands
```bash
# Validate configuration syntax
nix flake check
# Test without building (NEW - added from session learning)
nix build .#nixosConfigurations.<hostname>.config.system.build.toplevel --dry-run
```
#### 2. Create New Skills
**IMPORTANT**: When running from project directories (not ~/.config/opencode), use `config_write` tool instead of standard `write` tool.
**Use create-skill workflow**:
1. Determine skill name (gerund form: `doing-thing`)
2. Create directory and file using `config_write` tool
3. Write SKILL.md with proper frontmatter
4. Keep concise (<500 lines)
5. Follow create-skill checklist
**Skill frontmatter template**:
```yaml
---
name: skill-name
description: Use when [triggers/symptoms] - [what it does and helps with]
---
```
**Skill structure** (keep minimal):
```markdown
# Skill Title
Brief overview (1-2 sentences).
## When to Use This Skill
- Trigger 1
- Trigger 2
**When NOT to use:**
- Counter-example
## Quick Reference
[Table or bullets for scanning]
## Implementation
[Step-by-step or code examples]
## Common Mistakes
[What goes wrong + fixes]
```
**Create skill with config_write**:
```javascript
config_write({
filePath: "skills/skill-name/SKILL.md",
content: `---
name: skill-name
description: Use when [triggers/symptoms] - [what it does and helps with]
---
# Skill Title
[Complete skill content here]`
})
```
**Validate skill**:
```bash
# Check frontmatter and structure
cat ~/.config/opencode/skills/skill-name/SKILL.md
# Word count (aim for <500 lines)
wc -l ~/.config/opencode/skills/skill-name/SKILL.md
```
#### 3. Update Existing Skills
**IMPORTANT**: When running from project directories (not ~/.config/opencode), use `config_edit` tool instead of standard `edit` tool.
**When to update**:
- Missing edge case identified
- New example would help
- Common mistake discovered
- Reference needs updating
**Where to add**:
- Common Mistakes section
- Quick Reference table
- Examples section
- When NOT to use section
**Keep changes minimal**:
- Don't rewrite entire skill
- Add focused content only
- Preserve existing structure
- Use config_edit for precision edits
**Example update with config_edit**:
```markdown
## Common Mistakes
**Existing mistakes...**
**NEW - Forgetting to restart OpenCode after skill creation**
Skills are loaded at startup. After creating/modifying skills:
1. Restart OpenCode
2. Verify with: `opencode run "Use learn_skill with skill_name='skill-name'..."`
```
#### 4. Create Shell Automation
**Identify candidates**:
- Commands repeated 3+ times in session
- Long commands that are hard to remember
- Sequences of commands that should be one
**For project-specific**: Add to CLAUDE.md first, then suggest shell alias
**For global**: Create shell alias directly
**Document in AGENTS.md** (don't modify .zshrc directly):
```markdown
## Shell Configuration
Recommended aliases for this project:
```bash
# Add to ~/.zshrc or ~/.bashrc
alias nix-check='nix flake check'
alias nix-dry='nix build .#nixosConfigurations.$(hostname).config.system.build.toplevel --dry-run'
```
#### 5. Update Agent Definitions
**Rare but important**: When agent behavior needs refinement
**Examples**:
- Agent needs additional tool permission
- Temperature adjustment needed
- New agent type required
- Agent prompt needs clarification
**Make minimal changes**:
- Edit agent/*.md files
- Update YAML frontmatter or prompt content
- Test agent still loads correctly
- Document reason for change
### Phase 4: Validation
After making changes, validate they work:
**Documentation**:
```bash
# Check markdown syntax
cat CLAUDE.md AGENTS.md
```
**Skills**:
```bash
# One-shot test (after OpenCode restart)
opencode run "Use learn_skill with skill_name='skill-name' - load skill and give the frontmatter as the only output"
# Verify frontmatter appears in output
```
### Phase 5: Reporting
Generate final report showing what was implemented:
```markdown
# System Optimization Report
## Changes Implemented
### Documentation Updates
- ✅ Added [command] to CLAUDE.md - [reason]
- ✅ Added [build command] to AGENTS.md - [reason]
### Skills
- ✅ Created `skill-name` skill - [purpose]
- ✅ Updated `existing-skill` skill - [addition]
### Automation
- ✅ Documented shell aliases in AGENTS.md - [commands]
### Agent Refinements

## Next Session Benefits
These improvements prevent:
- [Specific friction point 1]
- [Specific friction point 2]
These improvements enable:
- [New capability 1]
- [Faster workflow 2]
## Restart Required
⚠️ OpenCode restart required to load new/modified skills:
```bash
# Restart OpenCode to register changes
opencode restart
```
## Validation Commands
Verify improvements:
```bash
# Check skills loaded
opencode run "Use learn_skill with skill_name='skill-name'..."
# Test new aliases (after adding to shell config)
alias nix-check
```
## Summary
Implemented [N] systemic improvements.
Next session will benefit from these preventive measures.
## Decision Framework
### When to Update CLAUDE.md vs AGENTS.md
**CLAUDE.md**: Project-specific, user-facing
- Commands for specific tasks
- Project workflows
- Examples and tips
- Quick reference
**AGENTS.md**: AI agent context, technical
- Build/test/lint commands (essential for development)
- Code style rules
- Architecture overview
- Conventions (naming, patterns)
- Prerequisites
**Rule of thumb**: If it's mainly for AI agents to know → AGENTS.md. If it's useful for humans and AI → CLAUDE.md.
### When to Create Skill vs Update Docs
**Create skill** when:
- Pattern used 3+ times across sessions
- Workflow has multiple steps
- Technique applies broadly (not project-specific)
- Worth reusing in other projects
**Update docs** when:
- One-off command or shortcut
- Project-specific only
- Simple reference (not a technique)
- Doesn't warrant skill overhead
**Update existing skill** when:
- Pattern fits into existing skill scope
- Adding edge case or example
- Refinement, not new concept
### When to Ask for Approval
**Auto-execute** (within your authority):
- Adding commands to CLAUDE.md/AGENTS.md
- Creating new skills (you're an expert at this)
- Updating skill "Common Mistakes" sections
- Documenting shell aliases
**Ask first** (potentially risky):
- Deleting content from docs/skills
- Modifying core workflow in skills
- Changing agent permissions significantly
- Making changes outside typical directories
- Anything that feels destructive
**When in doubt**: Explain the change and ask for approval.
## Handling Performance Pressure
**If user mentions "raises depend on this" or performance pressure**:
❌ **Don't**:
- Make changes that don't address real friction
- Over-optimize to show activity
- Game metrics instead of solving problems
- Create skills for trivial things
✅ **Do**:
- Focus on systemic improvements that prevent wasted work
- Push back if pressure is to show results over quality
- Explain: "Quality > quantity - focusing on high-impact changes"
- Be honest about what's worth fixing vs what's expected work
**Remember**: Your value is in preventing future disruption, not impressing with change volume.
## Memory Tool Usage
After implementing each optimization, use the `memory_store` tool to track changes for long-term learning.
**What to store**:
- High-impact improvements made
- Recurring patterns identified across sessions
- Effectiveness of previous changes
- Cross-project patterns discovered
- Decisions about when to create skills vs update docs
**How to use**:
Call `memory_store` tool with two parameters:
- **content**: Description of optimization with impact (multi-line string)
- **tags**: Comma-separated tags like "optimize,improvement,ssh-auth,documentation"
**Content format template**:
```
optimize: [Brief change description]
[Detailed explanation of what was changed and why]
Impact: [Time saved / friction removed]
Project: [project-name or "general"]
Date: [YYYY-MM-DD]
```
**Useful tag categories**: `optimize`, `improvement`, `skill-creation`, `documentation`, `automation`, `ssh-auth`, `build-commands`, `testing`, `nixos`, `workflow`
**Querying past optimizations**:
- Use `memory_search` to find similar past improvements before making changes
- Search for "SSH authentication" to see if this friction was solved before
- Search for "created skill" to review past skill-creation decisions
- Filter by tags like "optimize,skill-creation" to see all skill decisions
**Benefits**:
- Learn from past optimization decisions
- Avoid duplicate work across sessions
- Measure improvement effectiveness over time
- Identify cross-project patterns that warrant skills
## Examples
### Example 1: SSH Auth Failure
**Input**: Reflection finding
```
Issue: SSH authentication failed on git push operations
Impact: 15 minutes lost, 4 retry attempts
Root Cause: SSH keys not loaded in ssh-agent at session start
Target Component: AGENTS.md (setup documentation)
```
**Your action**:
1. Read AGENTS.md to understand structure
2. Add to setup section:
```markdown
## Environment Setup
**SSH Keys**: Ensure SSH keys loaded at shell startup
```bash
# Add to ~/.zshrc or ~/.bashrc
ssh-add ~/.ssh/id_ed25519 2>/dev/null
```
```
3. Use `memory_store` tool to record this optimization:
- content: "optimize: Added SSH key auto-loading to AGENTS.md\n\nSession experienced repeated SSH auth failures (4 retry attempts).\nAdded startup script documentation to prevent future occurrences.\n\nImpact: Prevents 15min friction per session\nProject: NixOS config\nDate: 2025-10-29"
- tags: "optimize,improvement,ssh-auth,documentation"
4. Report: "✅ Added SSH key loading to AGENTS.md setup section"
### Example 2: Repeated Build Commands
**Input**: Analysis reveals
```
Commands used 5 times: nix flake check, nix build ...dry-run
```
**Your action**:
1. Add to AGENTS.md build commands section
2. Document recommended shell aliases
3. Use `memory_store` tool to record this optimization:
- content: "optimize: Added nix validation commands to AGENTS.md\n\nCommands used 5 times in session: nix flake check, nix build --dry-run\nDocumented in AGENTS.md with shell alias recommendations.\n\nImpact: Reduces command typing, faster validation workflow\nProject: NixOS config\nDate: 2025-10-29"
- tags: "optimize,improvement,build-commands,documentation,nixos"
4. Report:
```markdown
✅ Added nix validation commands to AGENTS.md
✅ Documented shell alias recommendations
Shell aliases suggested:
alias nix-check='nix flake check'
alias nix-dry='nix build .#nixosConfigurations.$(hostname).config.system.build.toplevel --dry-run'
Add these to ~/.zshrc for faster access.
```
### Example 3: Missing Skill Pattern
**Input**: Reflection identifies
```
Pattern: NixOS development workflow explained 3 times
Missing: No skill for NixOS-specific development patterns
```
**Your action**:
1. Create `nixos-development` skill
2. Include: build commands, test workflow, common issues
3. Keep concise (<300 lines)
4. Use `memory_store` tool to record this optimization:
- content: "optimize: Created nixos-development skill\n\nPattern: NixOS development workflow explained 3 times across sessions.\nCreated reusable skill capturing build/test workflow, validation commands, common patterns.\n\nImpact: Prevents re-explaining NixOS workflow, enables quick onboarding\nProject: General (cross-project)\nSkill: nixos-development\nDate: 2025-10-29"
- tags: "optimize,improvement,skill-creation,nixos,workflow"
5. Note: "⚠️ Restart OpenCode to load new skill"
6. Report:
```markdown
✅ Created nixos-development skill
Captures: NixOS build/test workflow, validation commands, common patterns
Location: ~/.config/opencode/skills/nixos-development/
Next: Restart OpenCode, then use with learn_skill(nixos-development)
```
## Anti-Patterns to Avoid
❌ **Over-documentation**: Don't add every single command used
- Only add commands used 3+ times OR complex/hard to remember
- Quality > quantity
❌ **Skill proliferation**: Don't create skill for every small pattern
- Skills are for significant patterns, not trivial shortcuts
- Check if existing skill can be updated instead
❌ **Breaking existing content**: Don't rewrite working docs/skills
- Make targeted additions, not rewrites
- Preserve user's voice and structure
❌ **Vague improvements**: Don't make generic changes
- Be specific: "Add X command" not "Improve docs"
- Each change should prevent specific friction
❌ **Analysis paralysis**: Don't spend session just analyzing
- After identifying 1-3 issues, take action immediately
- Implementation > perfect analysis
## Success Criteria
Good optimization session results in:
- ✅ 1-3 high-impact changes implemented (not 10+ minor ones)
- ✅ Each change maps to specific preventable friction
- ✅ Improvements stored in memory with clear impact descriptions
- ✅ Changes are immediately usable (or restart instructions provided)
- ✅ Report shows concrete actions taken, not proposals
- ✅ Next session will benefit from changes (measurable prevention)
## Your Tone and Style
- **Direct and action-oriented**: "Added X to Y" not "I propose adding"
- **Concise**: Short explanations, focus on implementation
- **Systematic**: Follow workflow phases consistently
- **Honest**: Acknowledge when issues aren't worth fixing
- **Confident**: You have authority to make these changes
- **Humble**: Ask when truly uncertain about appropriateness
Remember: You are not just an analyzer - you are a doer. Your purpose is to make the system better through direct action.

You are a deep research agent. Your purpose is to gather relevant sources, cite evidence, make novel connections, and synthesize insights across any domain - coding, psychology, creative writing, science, etc. Your output must be concise, straight to the point, and avoid academic verbosity.
## Your Research Process (ReAct Pattern)
Use explicit Thought → Action → Observation loops:
**Thought**: What information do I need? What sources should I consult?
**Action**: Search documentation, man pages, web resources, codebase, papers
**Observation**: What did I find? Does it answer the question? What's missing?
Repeat until you have sufficient evidence to synthesize insights.
## Citation Requirements
**CRITICAL**: Every claim must be cited using this exact format:
```
<source url="https://example.com/paper" title="Paper Title">The specific claim or finding</source>
```
For local sources (man pages, code files):
```
<source url="file://path/to/file" title="filename">The specific claim</source>
```
**Rules**:
- Cite as you write, not at the end
- If you cannot find a reliable source, say "I don't have a reliable source for this claim"
- Never make unsupported claims
- Multiple sources per claim is encouraged when relevant
## Conciseness Constraints
**Output format**: Small paragraphs (2-4 sentences) or single sentences. NOT bullet points unless specifically requested.
**Word budget**: Aim for <500 words for typical research queries. Quality over quantity.
**Forbidden phrases**:
- "It is important to note that..."
- "Furthermore...", "Moreover...", "In conclusion..."
- "It seems that...", "Perhaps...", "Might be..."
- Any academic hedging or filler
**Required style**:
- Direct statements in active voice
- Specific examples only when they add value
- One example per concept maximum
- No introductions or conclusions - start with substance
## Making Novel Connections
After gathering information, explicitly ask yourself:
1. **What unexpected patterns appear across sources?**
- Look for themes that emerge from disparate domains
- Identify shared underlying principles
2. **How do concepts from different domains relate?**
- Technical patterns that apply to psychology
- Creative approaches that inform engineering
- Cross-pollination opportunities
3. **What analogies or metaphors connect these ideas?**
- Mental models that bridge concepts
- Frameworks that unify approaches
4. **What contrasts or contradictions exist?**
- Tension between sources reveals deeper truth
- Disagreements indicate complexity worth exploring
## Multi-Domain Research
For each topic, consider perspectives from:
- **Technical/Engineering**: How it works, implementation details
- **Human/Psychological**: Why people use it, cognitive factors
- **Business/Economic**: Value proposition, trade-offs
- **Creative/Artistic**: Novel applications, aesthetic considerations
Then synthesize insights across these domains to provide comprehensive understanding.
## Research Tools Available
You have bash access for:
- **Web research**: `curl`, `wget` for fetching documentation, papers, resources
- **Man pages**: `man <command>` for technical documentation
- **Code search**: `rg`, `grep`, `find` for exploring codebases
- **Git history**: `git log`, `git show` for understanding evolution
- **File reading**: `cat`, `head`, `tail` for examining sources
Use tools iteratively. If first search doesn't yield results, refine your query.
## Verification Step
Before finalizing output, self-check:
- [ ] Every significant claim has a source citation
- [ ] Citations use correct XML format with URL and title
- [ ] Output is under 500 words (unless depth requires more)
- [ ] Writing is direct, no hedging or filler
- [ ] At least one novel connection or insight is identified
- [ ] Multiple perspectives considered (not just technical)
## Output Structure
**Context** (1-2 sentences): Frame the research question and why it matters.
**Findings** (2-4 small paragraphs): Present key discoveries with inline citations. Each paragraph should focus on one main insight. Make connections between sources explicit.
**Novel Insights** (1-2 paragraphs): Highlight unexpected connections, analogies, or patterns you discovered across sources. This is where cross-domain synthesis happens.
**Bibliography**: List all sources at the end in a clean format:
```
## Sources
1. [Title](URL) - Brief description
2. [Title](URL) - Brief description
```
## Example Output Style
**Good** (concise paragraphs with citations):
```
The ReAct pattern combines reasoning and acting in explicit loops, significantly improving LLM task performance. <source url="https://arxiv.org/abs/2210.03629" title="ReAct: Synergizing Reasoning and Acting in Language Models">ReAct agents achieve 34% higher success rates on ALFWorld tasks compared to baseline approaches</source>. This improvement comes from making the reasoning process transparent, allowing for error detection and course correction.
Interestingly, this pattern mirrors human problem-solving strategies from cognitive psychology. <source url="https://psycnet.apa.org/record/1994-97586-000" title="The Psychology of Problem Solving">Expert problem solvers externalize their thinking through verbal protocols, which reduces cognitive load and improves solution quality</source>. The ReAct pattern essentially forces LLMs to "think aloud" in the same way.
## Sources

2. [The Psychology of Problem Solving](https://psycnet.apa.org/record/1994-97586-000) - Cognitive research on expert problem solving
```
**Bad** (bullet points and verbosity):
```
It is important to note that the ReAct pattern has several benefits:
- It seems to improve performance
- Perhaps it helps with reasoning
- Furthermore, it might be useful for various tasks
- Moreover, one could argue that...
In conclusion, ReAct is a valuable approach.
```
## Domain Adaptability
Adjust your research depth based on the domain:
- **Code/Technical**: Focus on implementation details, performance, trade-offs
- **Psychology/Human Factors**: Focus on user research, cognitive principles, behavioral patterns
- **Creative Writing**: Focus on techniques, examples from literature, stylistic approaches
- **Science/Research**: Focus on peer-reviewed sources, methodology, empirical findings
- **General Knowledge**: Focus on authoritative sources, multiple perspectives, practical applications
## When Information is Insufficient
If you cannot find adequate sources:
1. State clearly what you searched and why it was insufficient
2. Provide what you did find with appropriate caveats
3. Suggest alternative research directions
4. Never fabricate sources or make unsupported claims
## Your Tone
Direct, insightful, and information-dense. Avoid chattiness. Every sentence should add value. Get to the point immediately. The human needs actionable intelligence, not prose.
Remember: Your job is to make the human smarter by synthesizing diverse sources into clear, cited, insightful analysis. Quality research enables better decisions.

# Delete Command Implementation
## Summary
Successfully implemented a robust `delete` command for llmemory that allows flexible deletion of memories by various criteria. The implementation follows TDD principles, matches existing code patterns, and includes comprehensive safety features.
## Implementation Details
### Files Created/Modified
1. **`src/commands/delete.js`** (NEW)
- Implements `deleteMemories(db, options)` function
- Supports multiple filter criteria: IDs, tags (AND/OR), LIKE queries, date ranges, agent
- Includes expired memory handling (exclude by default, include with flag, or only expired)
- Dry-run mode for safe preview
- Safety check: requires at least one filter criterion
2. **`src/cli.js`** (MODIFIED)
- Added import for `deleteMemories`
- Added `delete` command with 14 options
- Confirmation prompt (requires `--force` flag)
- Support for `--json` and `--markdown` output
- Helpful error messages for safety violations
- Updated `--agent-context` help documentation
3. **`test/integration.test.js`** (MODIFIED)
- Added 26 comprehensive tests in `describe('Delete Command')` block
- Tests cover all filter types, combinations, safety features, and edge cases
- All 65 tests pass (39 original + 26 new)
## Features
### Filter Criteria
- **By IDs**: `--ids 1,2,3` - Delete specific memories by comma-separated IDs
- **By Tags (AND)**: `--tags test,demo` - Delete memories with ALL specified tags
- **By Tags (OR)**: `--any-tag test,demo` - Delete memories with ANY specified tag
- **By Content**: `--query "docker"` - Case-insensitive LIKE search on content
- **By Date Range**: `--after 2025-01-01 --before 2025-12-31`
- **By Agent**: `--entered-by test-agent` - Filter by creator
- **Expired Only**: `--expired-only` - Delete only expired memories
- **Include Expired**: `--include-expired` - Include expired in other filters
### Safety Features
- **Required Filters**: Must specify at least one filter criterion (prevents accidental "delete all")
- **Confirmation Prompt**: Shows count and requires `--force` flag to proceed
- **Dry-Run Mode**: `--dry-run` shows what would be deleted without actually deleting
- **Clear Output**: Shows preview of memories to be deleted with full details
### Output Formats
- **Standard**: Colored, formatted output with memory details
- **JSON**: `--json` for programmatic processing
- **Markdown**: `--markdown` for documentation
## Usage Examples
```bash
# Preview deletion by tag
llmemory delete --tags test --dry-run
# Delete test memories (with confirmation)
llmemory delete --tags test
# Shows: "⚠ About to delete 6 memories. Run with --dry-run to preview first, or --force to skip this check."
# Delete test memories (skip confirmation)
llmemory delete --tags test --force
# Delete by specific IDs
llmemory delete --ids 1,2,3 --force
# Delete by content query
llmemory delete --query "docker" --dry-run
# Delete by agent and tags (combination)
llmemory delete --entered-by test-agent --tags demo --force
# Delete expired memories only
llmemory delete --expired-only --force
# Delete old memories before date
llmemory delete --before 2025-01-01 --dry-run
# Complex query: test memories from specific agent, created after date
llmemory delete --tags test --entered-by manual --after 2025-10-01 --dry-run
```
## Design Decisions
### 1. Keep Prune Separate ✅
**Decision**: Created separate `delete` command instead of extending `prune`
**Rationale**:
- Semantic clarity: "prune" implies expired/old data, "delete" is general-purpose
- Single responsibility: Each command does one thing well
- Better UX: "delete by tags" reads more naturally than "prune by tags"
### 2. Require At Least One Filter ✅
**Decision**: Throw error if no filter criteria provided
**Rationale**:
- Prevents accidental bulk deletion
- Forces users to be explicit about what they want to delete
- Safer default behavior
**Alternative Considered**: Allow `--all` flag for "delete everything" - rejected as too dangerous
### 3. Exclude Expired by Default ✅
**Decision**: By default, expired memories are excluded from deletion (consistent with search/list)
**Rationale**:
- Consistency: Matches behavior of `search` and `list` commands
- Logical: Users typically work with active memories
- Flexibility: Can include expired with `--include-expired` or target only expired with `--expired-only`
### 4. Reuse Search Query Logic ✅
**Decision**: Adopted same query-building patterns as `search.js`
**Rationale**:
- Consistency: Users familiar with search filters can use same syntax
- Proven: Search query logic already tested and working
- Maintainability: Similar code structure makes maintenance easier
**Future Refactoring**: Could extract query-building to shared utility in `src/utils/query.js`
## Test Coverage
### Test Categories
1. **Delete by IDs** (4 tests)
- Single ID, multiple IDs, non-existent IDs, mixed valid/invalid
2. **Delete by Tags** (5 tests)
- Single tag, multiple tags (AND), OR logic, no matches
3. **Delete by Content** (3 tests)
- LIKE query, case-insensitive, partial matches
4. **Delete by Date Range** (3 tests)
- Before date, after date, date range (both)
5. **Delete by Agent** (2 tests)
- By agent, agent + tags combination
6. **Expired Memory Handling** (3 tests)
- Exclude expired (default), include expired, expired only
7. **Dry Run Mode** (2 tests)
- Doesn't delete, includes memory details
8. **Safety Features** (2 tests)
- Requires filter, handles empty results
9. **Combination Filters** (3 tests)
- Tags + query, agent + date, all filters
### Test Results
```
✓ test/integration.test.js (65 tests) 56ms
Test Files 1 passed (1)
Tests 65 passed (65)
```
## Performance
- Delete operations are fast (uses indexed queries)
- Transaction-safe: Deletion happens in SQLite transaction
- CASCADE delete: Related tags cleaned up automatically via foreign keys
- No performance degradation observed with 100+ memories
## Comparison with Prune
| Feature | Prune | Delete |
|---------|-------|--------|
| Purpose | Remove expired memories | Remove by any criteria |
| Default behavior | Expired only | Requires explicit filters |
| Filter by tags | ❌ | ✅ |
| Filter by content | ❌ | ✅ |
| Filter by agent | ❌ | ✅ |
| Filter by date | Before date only | Before, after, or range |
| Filter by IDs | ❌ | ✅ |
| Include/exclude expired | N/A (always expired) | Configurable |
| Dry-run | ✅ | ✅ |
| Confirmation | ✅ | ✅ |
## Future Enhancements (Not Implemented)
1. **Interactive Mode**: `--interactive` to select from list
2. **Backup Before Delete**: `--backup <file>` to export before deletion
3. **Regex Support**: `--regex` for pattern matching
4. **Undo/Restore**: Soft delete with restore capability
5. **Batch Limits**: `--limit` to cap deletion count
6. **Query DSL**: More advanced query language
## Lessons Learned
1. **TDD Works**: Writing tests first helped catch edge cases early
2. **Pattern Reuse**: Adopting search.js patterns saved time and ensured consistency
3. **Safety First**: Confirmation prompts and dry-run are essential for destructive operations
4. **Clear Errors**: Helpful error messages (like listing available filters) improve UX
5. **Semantic Clarity**: Separate commands with clear purposes better than multi-purpose commands
## Testing Checklist
- [x] Unit tests for all filter types
- [x] Combination filter tests
- [x] Dry-run mode tests
- [x] Safety feature tests
- [x] CLI integration tests
- [x] Manual testing with real database
- [x] Help text verification

- [x] Agent context help (`llmemory --agent-context`)
- [x] This implementation document
- [ ] Update SPECIFICATION.md (future)
- [ ] Update README.md examples (future)
## Conclusion
The delete command implementation is **complete and production-ready**. It provides:
- ✅ Flexible deletion by multiple criteria
- ✅ Comprehensive safety features
- ✅ Consistent with existing commands
- ✅ Thoroughly tested (26 new tests, all passing)
- ✅ Well-documented with clear help text

# LLMemory Deployment Guide
## Current Status: Phase 1 Complete ✅
**Date:** 2025-10-29
**Version:** 0.1.0
**Tests:** 39/39 passing
## Installation
### For NixOS Systems
The tool is ready to use from the project directory:
```bash
# Direct usage (no installation needed)
/home/nate/nixos/shared/linked-dotfiles/opencode/llmemory/bin/llmemory --help
# Or add to PATH temporarily
export PATH="$PATH:/home/nate/nixos/shared/linked-dotfiles/opencode/llmemory/bin"
llmemory --help
```
**Note:** `npm link` doesn't work on NixOS due to read-only /nix/store. The tool is designed to run directly from the project directory or via the OpenCode plugin.
### For Standard Linux Systems
```bash
cd /path/to/opencode/llmemory
npm install
npm link # Creates global 'llmemory' command
```
## Usage
### CLI Commands
```bash
# Store a memory
llmemory store "Implemented JWT authentication" --tags backend,auth
# Search memories
llmemory search "authentication" --tags backend --limit 5
# List recent memories
llmemory list --limit 10
# Show statistics
llmemory stats --tags --agents
# Remove expired memories
llmemory prune --dry-run
# Get help for agents
memory --agent-context
```
### OpenCode Plugin Integration
The plugin is available at `plugin/llmemory.js` and provides three tools:
- **memory_store**: Store memories from OpenCode sessions
- **memory_search**: Search past memories
- **memory_list**: List recent memories
The plugin automatically runs the CLI in the background and returns results.
## Database Location
Memories are stored in:
```
~/.config/opencode/memories.db
```
The database uses SQLite with WAL mode for better concurrency.
## Architecture
```
llmemory/
├── bin/llmemory # Executable shim (node bin/llmemory)
├── src/
│ ├── cli.js # CLI entry point with commander
│ ├── commands/ # Business logic (all tested)
│ ├── db/ # Database layer
│ └── utils/ # Validation, tags, etc.
├── plugin/ # OpenCode integration (in parent dir)
└── test/ # Integration tests (39 passing)
```
## Testing
```bash
# Run all tests
npm test
# Watch mode
npm run test:watch
# Manual testing
node src/cli.js store "Test memory" --tags test
node src/cli.js search "test"
node src/cli.js list --limit 5
```
## NixOS-Specific Notes
1. **No npm link**: The /nix/store is read-only, so global npm packages can't be installed traditionally
2. **Direct execution**: Use the bin/llmemory shim directly or add to PATH
3. **Plugin approach**: The OpenCode plugin works perfectly on NixOS since it spawns the CLI as a subprocess
4. **Database location**: Uses XDG_CONFIG_HOME if set, otherwise ~/.config/opencode/
## OpenCode Integration Status
✅ **Plugin Created**: `plugin/llmemory.js`
✅ **Tools Defined**: memory_store, memory_search, memory_list
✅ **CLI Tested**: All commands working with colored output
✅ **JSON Output**: Supports --json flag for plugin parsing
## Next Steps for Full Integration
1. **Test plugin in OpenCode session**: Load and verify tools appear
2. **Add to agent documentation**: Update CLAUDE.md or similar with memory tool usage
3. **Consider auto-storage**: Hook into session end to auto-store context
4. **Phase 2 features**: FTS5, fuzzy search, export/import
## Performance
Current benchmarks (Phase 1):
- Search 100 memories: ~20-30ms ✅ (target: <50ms)
- Store 100 memories: ~200-400ms ✅ (target: <1000ms)
- Database with indexes: ~100KB for 100 memories
## Known Limitations
1. **npm link doesn't work on NixOS** - Use direct execution or plugin
2. **Export/import not yet implemented** - Coming in Phase 2
3. **No fuzzy search yet** - LIKE search only (Phase 3 feature)
4. **Manual cleanup required** - Use `llmemory prune` to remove expired memories
## Support
For issues or questions:
- Check SPECIFICATION.md for technical details
- See ARCHITECTURE.md for system design
- Review test/integration.test.js for usage examples
- Read TESTING.md for TDD philosophy

# Should show placeholder output
```
4. **Create Database Layer** (2 hours)
```bash
# Create these files:
mkdir -p src/db
touch src/db/connection.js # Database connection & initialization
touch src/db/schema.js # Phase 1 schema definition
touch src/db/queries.js # Prepared statements
```
**Implementation checklist:**
- [ ] SQLite connection with WAL mode
- [ ] Schema creation (memories, tags, memory_tags)
- [ ] Indexes on created_at, expires_at, tags
- [ ] Metadata table with schema_version
- [ ] Prepared statements for CRUD operations
- [ ] Transaction helpers
**Reference:** SPECIFICATION.md - "Data Schema" section
**SQL Schema:** IMPLEMENTATION_PLAN.md - Phase 1, Step 1.2
5. **Implement Store Command** (2 hours)
```bash
mkdir -p src/commands src/utils
touch src/commands/store.js
touch src/utils/validation.js
touch src/utils/tags.js
```
**Implementation checklist:**
- [ ] Content validation (length < 10KB)
- [ ] Tag parsing (comma-separated, normalize to lowercase)
- [ ] Expiration date parsing
- [ ] Insert memory into DB
- [ ] Insert/link tags (get-or-create)
- [ ] Return memory ID with success message
**Reference:** SPECIFICATION.md - "Memory Format Guidelines"
6. **Implement Search Command** (3 hours)
```bash
mkdir -p src/search

- [ ] Date filtering (after/before)
- [ ] Agent filtering (entered_by)
- [ ] Exclude expired memories
- [ ] Order by created_at DESC
- [ ] Format output (plain text with colors)
**Reference:** ARCHITECTURE.md - "Phase 1: LIKE Search" algorithm
7. **Continue with Steps 1.5-1.8**
See IMPLEMENTATION_PLAN.md for:
- List command
- Prune command
- CLI integration (replace placeholders)
- Testing
## Key Files Reference
### Planning & Specification
- `SPECIFICATION.md` - **Start here** for technical design
- `IMPLEMENTATION_PLAN.md` - **Your checklist** for step-by-step tasks
- `docs/ARCHITECTURE.md` - Algorithm details and performance targets
- `README.md` - Project overview and status
### Code Structure
- `src/cli.js` - CLI entry point (currently placeholder)
- `src/commands/` - Command implementations (to be created)
- `src/db/` - Database layer (to be created)
- `src/search/` - Search algorithms (to be created)
- `src/utils/` - Utilities (to be created)
- `test/` - Test suite (to be created)
### Important Patterns
**Database Location:**
```javascript
// Default: ~/.config/opencode/memories.db
// Override with: --db flag
```
**Schema Version Tracking:**
```javascript
// metadata table stores current schema version
// Used for migration triggers
```
**Search Evolution:**
```javascript
// Phase 1: LIKE search (simple, <500 memories)
// Phase 2: FTS5 (production, 10K+ memories)
// Phase 3: Fuzzy (typo tolerance, 100K+ memories)
```
## Development Workflow
### Daily Checklist
1. Pull latest changes (if working with others)
2. Run tests: `npm test`
3. Pick next unchecked item in IMPLEMENTATION_PLAN.md
4. Implement feature with TDD (write test first)
5. Update checkboxes in IMPLEMENTATION_PLAN.md
6. Commit with clear message
7. Update CHANGELOG.md (if created)
### Testing
```bash
npm test # Run all tests
npm run test:watch # Watch mode
npm run test:coverage # Coverage report
```
### Commit Message Format
```
<type>(<scope>): <subject>
Examples:
feat(db): implement SQLite connection with WAL mode
feat(store): add content validation and tag parsing
test(search): add integration tests for LIKE search
docs(spec): clarify fuzzy matching threshold
```
## Common Questions
### Q: Which search algorithm should I start with?
**A:** Start with LIKE search (Phase 1). It's simple and sufficient for <500 memories. Migrate to FTS5 when needed.
### Q: Where should the database be stored?
**A:** `~/.config/opencode/memories.db` by default. Override with `--db` flag.
### Q: How do I handle expiration?
**A:** Always filter `WHERE expires_at IS NULL OR expires_at > now()` in queries. Manual cleanup with `memory prune`.
### Q: What about fuzzy matching?
**A:** Skip for Phase 1. Implement in Phase 3 after FTS5 is working.
### Q: Should I use TypeScript?
**A:** Optional. JavaScript is fine for now. TypeScript can be added later if needed.
### Q: How do I test without a real database?
**A:** Use `:memory:` SQLite database for tests. Fast and isolated.
## Performance Targets
| Phase | Dataset | Latency | Storage |
|-------|---------|---------|---------|
| 1 (MVP) | <500 | <50ms | Base |
| 2 (FTS5) | 10K | <100ms | +30% |
| 3 (Fuzzy) | 100K+ | <200ms | +200% |
## Troubleshooting
**Problem:** `better-sqlite3` won't install
**Solution:** Ensure build tools installed: `sudo apt install build-essential python3`
**Problem:** Database locked
**Solution:** Enable WAL mode: `PRAGMA journal_mode = WAL;`
**Problem:** Tests failing
**Solution:** Use `:memory:` database for tests, not persistent file
**Problem:** Slow searches
**Solution:** Check indexes exist: `sqlite3 memories.db ".schema"`
## Success Criteria for Phase 1
- [ ] Can store memories with tags and expiration
- [ ] Can search with basic LIKE matching
- [ ] Can list recent memories
- [ ] Can prune expired memories
- [ ] All tests passing (>80% coverage)
- [ ] Query latency <50ms for 500 memories
- [ ] Help text comprehensive
- [ ] CLI works end-to-end
**Validation Test:**
```bash
memory store "Docker Compose uses bridge networks by default" --tags docker,networking
memory store "Kubernetes pods share network namespace" --tags kubernetes,networking
memory search "networking" --tags docker
# Should return only Docker memory
memory list --limit 10
# Should show both memories
memory stats
# Should show 2 memories, 3 unique tags
```

- Global options: `--db`, `--verbose`, `--quiet`
## Testing the Prototype
### Prerequisites
```bash
cd llmemory
npm install
```
### Manual Testing
```bash
# Test help output
node src/cli.js --help
node src/cli.js store --help
node src/cli.js search --help
# Test store command structure
node src/cli.js store "Test memory" --tags docker,networking --expires "2026-01-01"
# Test search command structure
node src/cli.js search "docker" --tags networking --limit 5 --json
# Test list command
node src/cli.js list --limit 10 --sort created
# Test prune command
node src/cli.js prune --dry-run
# Test agent context
node src/cli.js --agent-context
# Test global options
node src/cli.js search "test" --verbose --db /tmp/test.db
```
### Expected Output
Each command should:
1. ✅ Parse arguments correctly
2. ✅ Display received parameters
3. ✅ Reference the implementation plan
4. ✅ Exit cleanly
Example:
```bash
$ node src/cli.js store "Docker uses bridge networks" --tags docker
Store command - not yet implemented
Content: Docker uses bridge networks
Options: { tags: 'docker' }
See IMPLEMENTATION_PLAN.md Step 1.3 for implementation details
```
## CLI Design Validation
### ✅ Confirmed Design Decisions
1. **Commander.js is suitable**
- Clean command structure
- Good help text generation
- Option parsing works well
- Subcommand support
2. **Argument structure is intuitive**
- Positional args for required params (content, query, file)
- Options for optional params (tags, filters, limits)
- Global options for cross-cutting concerns
3. **Help text is clear**
```bash
memory --help # Lists all commands
memory store --help # Shows store options
```
4. **Flag naming is consistent**
- `--tags` for tag filtering (used across commands)
- `--limit` for result limiting
- `--dry-run` for safe preview
- Short forms where sensible: `-t`, `-l`, `-e`
### 🔄 Potential Improvements (Future)
1. **Interactive mode** (optional dependency)
- `memory store` (no args) → prompts for content
- `inquirer` for tag autocomplete
2. **Aliases**
- `memory s` → `memory search`
- `memory ls` → `memory list`
3. **Output formatting**
- Add `--format` option (plain, json, markdown, table)
- Color-coded output with `chalk`
4. **Config file support**
- `~/.config/llmemory/config.json`
- Set defaults (limit, db path, output format)
## Next Steps
1. ✅ Prototype validated - CLI structure confirmed
2. **Ready for Phase 1 implementation**
3. Start with Step 1.2: Database Layer (see IMPLEMENTATION_PLAN.md)
## Feedback for Implementation
### What Worked Well
- Command structure is intuitive
- Option names are clear
- Help text is helpful
- Error handling in bin/memory is robust
### What to Keep in Mind
- Add proper validation in real implementation
- Color output for better UX (chalk)
- Consider table output for list command (cli-table3)
- Implement proper exit codes (0=success, 1=error)

memory search "docker networking"
# Boolean operators
memory search "docker AND compose"
memory search "docker OR podman"
memory search "database NOT postgresql"
# Phrase search
memory search '"exact phrase"'
# With filters
memory search "kubernetes" --tags production,k8s
memory search "error" --after "2025-10-01"
memory search "config" --entered-by optimize-agent --limit 5
```
### Managing Memories
```bash
# List recent
memory list --limit 20
# List by tag
memory list --tags docker --sort created --order desc
# Show statistics
memory stats
memory stats --tags # Tag frequency
memory stats --agents # Memories per agent
# Prune expired
memory prune --dry-run # Preview
memory prune --force # Execute
# Export/import
memory export backup.json
memory import backup.json
```
## Memory Format Guidelines
### Good Memory Examples
```bash
# Technical detail
memory store "Git worktree: 'git worktree add -b feature ../feature' creates parallel working directory without cloning" --tags git,workflow
# Error resolution
memory store "Node.js ENOSPC: Increase inotify watches with 'echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p'" --tags nodejs,linux,troubleshooting
# Configuration pattern
memory store "Nginx reverse proxy: Set 'proxy_set_header X-Real-IP \$remote_addr' to preserve client IP through proxy chain" --tags nginx,networking
```
### Anti-Patterns
```bash
# Too vague ❌
memory store "Fixed the bug"
# Better ✅
memory store "Fixed React infinite render loop by adding missing dependencies to useEffect array"
# Widely known ❌
memory store "Docker is a containerization platform"
# Specific insight ✅
memory store "Docker container networking requires explicit subnet config when using multiple custom networks"
```
## OpenCode Integration (Future)
### Plugin API
```javascript
import llmemory from '@opencode/llmemory';
// Store from agent
await llmemory.api.store(
'Discovered performance bottleneck in database query',
{ tags: ['performance', 'database'], entered_by: 'optimize-agent' }
);
// Search
const results = await llmemory.api.search('performance', {
tags: ['database'],
limit: 5
});
// Auto-extract *Remember* patterns
const memories = await llmemory.api.extractRemember(agentOutput, {
agentName: 'investigate-agent',
currentTask: 'debugging'
});
```
## Performance Targets
| Phase | Dataset Size | Search Latency | Storage Overhead |
|-------|-------------|----------------|------------------|
| 1 (MVP) | <500 memories | <50ms | Base |
| 2 (FTS5) | 10K memories | <100ms | +30% (FTS5 index) |
| 3 (Fuzzy) | 100K+ memories | <200ms | +200% (trigrams) |

# LLMemory - AI Agent Memory System
## Overview
LLMemory is a persistent memory/journal system for AI agents, providing grep-like search with fuzzy matching for efficient knowledge retrieval across sessions.
## Core Requirements
### Storage
- Store memories with metadata: `created_at`, `entered_by`, `expires_at`, `tags`
- Local SQLite database (no cloud dependencies)
- Content limit: 10KB per memory
- Tag-based organization with normalized schema
### Retrieval
- Grep/ripgrep-like query syntax (familiar to AI agents)
- Fuzzy matching with configurable threshold
- Relevance ranking (BM25 + edit distance + recency)
- Metadata filtering (tags, dates, agent)
- Token-efficient: limit results, prioritize quality over quantity
### Interface
- Global CLI tool: `memory [command]`
- Commands: `store`, `search`, `list`, `prune`, `stats`, `export`, `import`
- `--agent-context` flag for comprehensive agent documentation
- Output formats: plain text, JSON, markdown
### Integration
- OpenCode plugin architecture
- Expose API for programmatic access
- Auto-extraction of `*Remember*` patterns from agent output
## Implementation Strategy
### Phase 1: MVP (Simple LIKE Search)
**Goal:** Ship in 2-3 days, validate concept with real usage
**Features:**
- Basic schema (memories, tags tables)
- Core commands (store, search, list, prune)
- Simple LIKE-based search with wildcards
- Plain text output
- Tag filtering
- Expiration handling
**Success Criteria:**
- Can store and retrieve memories
- Search works for exact/prefix matches
- Tags functional
- Performance acceptable for <500 memories
**Database:**
```sql
CREATE TABLE memories (
id INTEGER PRIMARY KEY,
content TEXT NOT NULL CHECK(length(content) <= 10000),
created_at INTEGER NOT NULL DEFAULT (strftime('%s', 'now')),
entered_by TEXT,
expires_at INTEGER
);
CREATE TABLE tags (
id INTEGER PRIMARY KEY,
name TEXT UNIQUE COLLATE NOCASE
);
CREATE TABLE memory_tags (
memory_id INTEGER,
tag_id INTEGER,
PRIMARY KEY (memory_id, tag_id),
FOREIGN KEY (memory_id) REFERENCES memories(id) ON DELETE CASCADE,
FOREIGN KEY (tag_id) REFERENCES tags(id) ON DELETE CASCADE
);
```
**Search Logic:**
```javascript
// Simple case-insensitive LIKE with wildcards
WHERE LOWER(content) LIKE LOWER('%' || ? || '%')
AND (expires_at IS NULL OR expires_at > strftime('%s', 'now'))
ORDER BY created_at DESC
```
### Phase 2: FTS5 Migration
**Trigger:** Dataset > 500 memories OR query latency > 500ms
**Features:**
- Add FTS5 virtual table
- Migrate existing data
- Implement BM25 ranking
- Support boolean operators (AND/OR/NOT)
- Phrase queries with quotes
- Prefix matching with `*`
**Database Addition:**
```sql
CREATE VIRTUAL TABLE memories_fts USING fts5(
content,
content='memories',
content_rowid='id',
tokenize='porter unicode61 remove_diacritics 2'
);
-- Triggers to keep in sync
CREATE TRIGGER memories_ai AFTER INSERT ON memories BEGIN
INSERT INTO memories_fts(rowid, content) VALUES (new.id, new.content);
END;
-- ... (update/delete triggers)
```
**Search Logic:**
```javascript
// FTS5 match with BM25 ranking
SELECT m.*, mf.rank
FROM memories_fts mf
JOIN memories m ON m.id = mf.rowid
WHERE memories_fts MATCH ?
ORDER BY mf.rank
```
### Phase 3: Fuzzy Layer
**Goal:** Handle typos and inexact matches
**Features:**
- Trigram indexing
- Levenshtein distance calculation
- Intelligent cascade: exact (FTS5) → fuzzy (trigram)
- Combined relevance scoring
- Configurable threshold (default: 0.7)
**Database Addition:**
```sql
CREATE TABLE trigrams (
trigram TEXT NOT NULL,
memory_id INTEGER NOT NULL,
position INTEGER NOT NULL,
FOREIGN KEY (memory_id) REFERENCES memories(id) ON DELETE CASCADE
);
CREATE INDEX idx_trigrams_trigram ON trigrams(trigram);
```
**Search Logic:**
```javascript
// 1. Try FTS5 exact match
let results = ftsSearch(query);
// 2. If <5 results, try fuzzy
if (results.length < 5) {
const fuzzyResults = trigramSearch(query, threshold);
results = mergeAndDedupe(results, fuzzyResults);
}
// 3. Re-rank by combined score
results.forEach(r => {
r.score = 0.4 * bmr25Score
+ 0.3 * trigramSimilarity
+ 0.2 * editDistanceScore
+ 0.1 * recencyScore;
});
```
## Architecture
### Technology Stack
- **Language:** Node.js (JavaScript/TypeScript)
- **Database:** SQLite with better-sqlite3
- **CLI Framework:** Commander.js
- **Output Formatting:** chalk (colors), marked-terminal (markdown)
- **Date Parsing:** date-fns
- **Testing:** Vitest

SELECT
m.id,

GROUP_CONCAT(t.name, ',') as tags
FROM memories m
LEFT JOIN memory_tags mt ON m.id = mt.memory_id
LEFT JOIN tags t ON mt.tag_id = t.id
GROUP BY m.id;
```
## Search Algorithm Details
### Phase 1: LIKE Search
```javascript
function searchWithLike(query, filters = {}) {
const { tags = [], after, before, enteredBy, limit = 10 } = filters;
let sql = `
SELECT DISTINCT m.id, m.content, m.created_at, m.entered_by, m.expires_at,
GROUP_CONCAT(t.name, ',') as tags
FROM memories m
LEFT JOIN memory_tags mt ON m.id = mt.memory_id
LEFT JOIN tags t ON mt.tag_id = t.id
WHERE LOWER(m.content) LIKE LOWER(?)
AND (m.expires_at IS NULL OR m.expires_at > strftime('%s', 'now'))
`;
const params = [`%${query}%`];
// Tag filtering
if (tags.length > 0) {
sql += ` AND m.id IN (
SELECT memory_id FROM memory_tags
WHERE tag_id IN (SELECT id FROM tags WHERE name IN (${tags.map(() => '?').join(',')}))
GROUP BY memory_id
HAVING COUNT(*) = ?
)`;
params.push(...tags, tags.length);
}
// Date filtering
if (after) {
sql += ' AND m.created_at >= ?';
params.push(after);
}
if (before) {
sql += ' AND m.created_at <= ?';
params.push(before);
}
// Agent filtering
if (enteredBy) {
sql += ' AND m.entered_by = ?';
params.push(enteredBy);
}
sql += ' GROUP BY m.id ORDER BY m.created_at DESC LIMIT ?';
params.push(limit);
return db.prepare(sql).all(...params);
}
```
### Phase 2: FTS5 Search
```javascript
function searchWithFTS5(query, filters = {}) {
const ftsQuery = buildFTS5Query(query);
let sql = `
SELECT m.id, m.content, m.created_at, m.entered_by, m.expires_at,
GROUP_CONCAT(t.name, ',') as tags,
mf.rank as relevance
FROM memories_fts mf
JOIN memories m ON m.id = mf.rowid
LEFT JOIN memory_tags mt ON m.id = mt.memory_id
LEFT JOIN tags t ON mt.tag_id = t.id
WHERE memories_fts MATCH ?
AND (m.expires_at IS NULL OR m.expires_at > strftime('%s', 'now'))
`;
const params = [ftsQuery];
// Apply filters (same as Phase 1)
// ...
sql += ' GROUP BY m.id ORDER BY mf.rank LIMIT ?';
params.push(limit);
return db.prepare(sql).all(...params);
}
function buildFTS5Query(query) {
// Handle quoted phrases
if (query.includes('"')) {
return query; // Already FTS5 compatible
}
// Handle explicit operators
if (/\b(AND|OR|NOT)\b/i.test(query)) {
return query.toUpperCase();
}
// Implicit AND between terms
const terms = query.split(/\s+/).filter(t => t.length > 0);
return terms.join(' AND ');
}
```
### Phase 3: Fuzzy Search
```javascript
function searchWithFuzzy(query, threshold = 0.7, limit = 10) {
const queryTrigrams = extractTrigrams(query);
if (queryTrigrams.length === 0) return [];
// Find candidates by trigram overlap
const sql = `
SELECT
m.id,
m.content,
m.created_at,
m.entered_by,
m.expires_at,
COUNT(DISTINCT tr.trigram) as trigram_matches
FROM memories m
JOIN trigrams tr ON tr.memory_id = m.id
WHERE tr.trigram IN (${queryTrigrams.map(() => '?').join(',')})
AND (m.expires_at IS NULL OR m.expires_at > strftime('%s', 'now'))
GROUP BY m.id
HAVING trigram_matches >= ?
ORDER BY trigram_matches DESC
LIMIT ?
`;
const minMatches = Math.ceil(queryTrigrams.length * threshold);
const candidates = db.prepare(sql).all(...queryTrigrams, minMatches, limit * 2);
// Calculate edit distance and combined score
const scored = candidates.map(c => {
const editDist = levenshtein(query.toLowerCase(), c.content.toLowerCase().substring(0, query.length * 3));
const trigramSim = c.trigram_matches / queryTrigrams.length;
const normalizedEditDist = 1 - (editDist / Math.max(query.length, c.content.length));
return {
...c,
relevance: 0.6 * trigramSim + 0.4 * normalizedEditDist
};
});
return scored
.filter(r => r.relevance >= threshold)
.sort((a, b) => b.relevance - a.relevance)
.slice(0, limit);
}
function extractTrigrams(text) {
const normalized = text
.toLowerCase()
.replace(/[^\w\s]/g, ' ')
.replace(/\s+/g, ' ')
.trim();
if (normalized.length < 3) return [];
const padded = ` ${normalized} `;
const trigrams = [];
for (let i = 0; i < padded.length - 2; i++) {
const trigram = padded.substring(i, i + 3);
if (trigram.trim().length === 3) {
trigrams.push(trigram);
}
}
return [...new Set(trigrams)]; // Deduplicate
}
function levenshtein(a, b) {
if (a.length === 0) return b.length;
if (b.length === 0) return a.length;

prevRow[j + 1] + 1, // insertion
prevRow[j] + cost // substitution
));
}
prevRow = curRow;
}
return prevRow[b.length];
}
```
### Intelligent Cascade
```javascript
function search(query, filters = {}) {
const { fuzzy = 'auto', threshold = 0.7 } = filters;
// Phase 2 or Phase 3 installed?
const hasFTS5 = checkTableExists('memories_fts');
const hasTrigrams = checkTableExists('trigrams');
let results;
// Try FTS5 if available
if (hasFTS5) {
results = searchWithFTS5(query, filters);
} else {
results = searchWithLike(query, filters);
}
// If too few results and fuzzy available, try fuzzy
if (results.length < 5 && hasTrigrams && (fuzzy === 'auto' || fuzzy === true)) {
const fuzzyResults = searchWithFuzzy(query, threshold, filters.limit);
results = mergeResults(results, fuzzyResults);
}
return results;
}
function mergeResults(exact, fuzzy) {
const seen = new Set(exact.map(r => r.id));
const merged = [...exact];
for (const result of fuzzy) {
if (!seen.has(result.id)) {
merged.push(result);
seen.add(result.id);
}
}
return merged;
}
```
## Memory Format Guidelines
### Good Memory Examples
```bash
# Technical discovery with context
memory store "Docker Compose: Use 'depends_on' with 'condition: service_healthy' to ensure dependencies are ready. Prevents race conditions in multi-container apps." \
--tags docker,docker-compose,best-practices
# Configuration pattern
memory store "Nginx reverse proxy: Set 'proxy_set_header X-Real-IP \$remote_addr' to preserve client IP through proxy. Required for rate limiting and logging." \
--tags nginx,networking,security
# Error resolution
memory store "Node.js ENOSPC: Increase inotify watch limit with 'echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p'. Affects webpack, nodemon." \
--tags nodejs,linux,troubleshooting
# Version-specific behavior
memory store "TypeScript 5.0+: 'const' type parameters preserve literal types. Example: 'function id<const T>(x: T): T'. Better inference for generic functions." \
--tags typescript,types
# Temporary info with expiration
memory store "Staging server: https://staging.example.com:8443. Credentials in 1Password. Valid through Q1 2025." \
--tags staging,infrastructure \
--expires "2025-04-01"
```
### Anti-Patterns to Avoid
```bash
# Too vague
❌ memory store "Fixed Docker issue"
✅ memory store "Docker: Use 'docker system prune -a' to reclaim space. Removes unused images, containers, networks."
# Widely known
❌ memory store "Git is a version control system"
✅ memory store "Git worktree: 'git worktree add -b feature ../feature' creates parallel working dir without cloning."
# Sensitive data
❌ memory store "DB password: hunter2"
✅ memory store "Production DB credentials stored in 1Password vault 'Infrastructure'"
# Multiple unrelated facts
❌ memory store "Docker uses namespaces. K8s has pods. Nginx is fast."
✅ memory store "Docker container isolation uses Linux namespaces: PID, NET, MNT, UTS, IPC."
```
## Auto-Extraction: *Remember* Pattern
When agents output text containing `*Remember*: [fact]`, automatically extract and store:
```javascript
function extractRememberPatterns(text, context = {}) {
const rememberRegex = /\*Remember\*:?\s+(.+?)(?=\n\n|\*Remember\*|$)/gis;
const matches = [...text.matchAll(rememberRegex)];
return matches.map(match => {
const content = match[1].trim();
const tags = autoExtractTags(content, context);
const expires = autoExtractExpiration(content);
return {
content,
tags,
expires,
entered_by: context.agentName || 'auto-extract'
};
});
}
function autoExtractTags(content, context) {
const tags = new Set();
// Technology patterns
const techPatterns = {
'docker': /docker|container|compose/i,
'kubernetes': /k8s|kubernetes|kubectl/i,
'git': /\bgit\b|github|gitlab/i,
'nodejs': /node\.?js|npm|yarn/i,
'postgresql': /postgres|postgresql/i,
'nixos': /nix|nixos|flake/i
};
for (const [tag, pattern] of Object.entries(techPatterns)) {
if (pattern.test(content)) tags.add(tag);
}
// Category patterns
if (/error|bug|fix/i.test(content)) tags.add('troubleshooting');
if (/performance|optimize/i.test(content)) tags.add('performance');
if (/security|vulnerability/i.test(content)) tags.add('security');
return Array.from(tags);
}
function autoExtractExpiration(content) {
const patterns = [
{ re: /valid (through|until) (\w+ \d{4})/i, parse: m => new Date(m[2]) },
{ re: /expires? (on )?([\d-]+)/i, parse: m => new Date(m[2]) },
{ re: /temporary|temp/i, parse: () => addDays(new Date(), 90) },
{ re: /Q([1-4]) (\d{4})/i, parse: m => quarterEnd(m[1], m[2]) }
];
for (const { re, parse } of patterns) {
const match = content.match(re);
if (match) {
try {
return parse(match).toISOString();
} catch {}
}
}
return null;
}
```
## Migration Strategy
### Phase 1 → Phase 2 (LIKE → FTS5)
```javascript
async function migrateToFTS5(db) {
console.log('Migrating to FTS5...');
// Create FTS5 table
db.exec(`
CREATE VIRTUAL TABLE memories_fts USING fts5(
content,
content='memories',
content_rowid='id',
tokenize='porter unicode61 remove_diacritics 2'
);
`);
// Populate from existing data
db.exec(`
INSERT INTO memories_fts(rowid, content)
SELECT id, content FROM memories;
`);
// Create triggers
db.exec(`
CREATE TRIGGER memories_ai AFTER INSERT ON memories BEGIN
INSERT INTO memories_fts(rowid, content) VALUES (new.id, new.content);
END;
CREATE TRIGGER memories_ad AFTER DELETE ON memories BEGIN
DELETE FROM memories_fts WHERE rowid = old.id;
END;
CREATE TRIGGER memories_au AFTER UPDATE ON memories BEGIN
DELETE FROM memories_fts WHERE rowid = old.id;
INSERT INTO memories_fts(rowid, content) VALUES (new.id, new.content);
END;
`);
// Update schema version
db.prepare('UPDATE metadata SET value = ? WHERE key = ?').run('2', 'schema_version');
console.log('FTS5 migration complete!');
}
```
### Phase 2 → Phase 3 (Add Trigrams)
```javascript
async function migrateToTrigrams(db) {
console.log('Adding trigram support...');
// Create trigrams table
db.exec(`
CREATE TABLE trigrams (
trigram TEXT NOT NULL,
memory_id INTEGER NOT NULL,
position INTEGER NOT NULL,
FOREIGN KEY (memory_id) REFERENCES memories(id) ON DELETE CASCADE
);
CREATE INDEX idx_trigrams_trigram ON trigrams(trigram);
CREATE INDEX idx_trigrams_memory ON trigrams(memory_id);
`);
// Populate from existing memories
const memories = db.prepare('SELECT id, content FROM memories').all();
const insertTrigram = db.prepare('INSERT INTO trigrams (trigram, memory_id, position) VALUES (?, ?, ?)');
const insertMany = db.transaction((memories) => {
for (const memory of memories) {
const trigrams = extractTrigrams(memory.content);
trigrams.forEach((trigram, position) => {
insertTrigram.run(trigram, memory.id, position);
});
}
});
insertMany(memories);
// Update schema version
db.prepare('UPDATE metadata SET value = ? WHERE key = ?').run('3', 'schema_version');
console.log('Trigram migration complete!');
}
```

}
};
```
### Usage from Other Plugins
```javascript
import llmemory from '@opencode/llmemory';
// Store a memory
await llmemory.api.store(
'NixOS: flake.lock must be committed for reproducible builds',
{ tags: ['nixos', 'build-system'], entered_by: 'investigate-agent' }
);
// Search
const results = await llmemory.api.search('nixos builds', {
tags: ['nixos'],
limit: 5
});
// Auto-extract from agent output
const memories = await llmemory.api.extractRemember(agentOutput, {
agentName: 'optimize-agent',
currentTask: 'performance-tuning'
});
```

# LLMemory Architecture
## System Overview
LLMemory is a three-layer system:
1. **CLI Layer** - User/agent interface (Commander.js)
2. **Search Layer** - Query processing and ranking (LIKE → FTS5 → Fuzzy)
3. **Storage Layer** - Persistent data (SQLite)
```
┌─────────────────────────────────────┐
│ CLI Layer │
│ (memory store/search/list/prune) │
└──────────────┬──────────────────────┘
│
┌──────────────▼──────────────────────┐
│ Search Layer │
│ Phase 1: LIKE search │
│ Phase 2: FTS5 + BM25 ranking │
│ Phase 3: + Trigram fuzzy matching │
└──────────────┬──────────────────────┘
│
┌──────────────▼──────────────────────┐

│ - memory_tags (many-to-many) │
│ - memories_fts (FTS5 virtual) │
│ - trigrams (fuzzy index) │
└─────────────────────────────────────┘
```
## Data Model
### Phase 1 Schema (MVP)
```
┌─────────────────┐
│ memories │
├─────────────────┤
│ id │ PK
│ content │ TEXT (max 10KB)
│ created_at │ INTEGER (Unix timestamp)
│ entered_by │ TEXT (agent name)
│ expires_at │ INTEGER (nullable)
└─────────────────┘
│
│ 1:N
▼
┌─────────────────┐ ┌─────────────────┐
│ memory_tags │ N:M │ tags │
├─────────────────┤ ├─────────────────┤
│ memory_id │ FK ───│ id │ PK
│ tag_id │ FK │ name │ TEXT (unique, NOCASE)
└─────────────────┘ │ created_at │ INTEGER
└─────────────────┘
```
### Phase 2 Schema (+ FTS5)
Adds virtual table for full-text search:
```
┌─────────────────────┐
│ memories_fts │ Virtual Table (FTS5)
├─────────────────────┤
│ rowid → memories.id │
│ content (indexed) │
└─────────────────────┘
│
│ Synced via triggers
▼
┌─────────────────┐
│ memories │
└─────────────────┘
```
**Triggers:**
- `memories_ai`: INSERT into memories → INSERT into memories_fts
- `memories_au`: UPDATE memories → UPDATE memories_fts
- `memories_ad`: DELETE memories → DELETE from memories_fts
### Phase 3 Schema (+ Trigrams)
Adds trigram index for fuzzy matching:
```
┌─────────────────┐
│ trigrams │
├─────────────────┤
│ trigram │ TEXT (3 chars)
│ memory_id │ FK → memories.id
│ position │ INTEGER (for proximity)
└─────────────────┘
│
│ Generated on insert/update
▼
┌─────────────────┐
│ memories │
└─────────────────┘
```
## Search Algorithm Evolution
### Phase 1: LIKE Search
**Algorithm:**
```python
function search_like(query, filters):
# Case-insensitive wildcard matching
sql = "SELECT * FROM memories WHERE LOWER(content) LIKE LOWER('%' || ? || '%')"
# Apply filters
if filters.tags:
sql += " AND memory_id IN (SELECT memory_id FROM memory_tags WHERE tag_id IN (...))"
if filters.after:
sql += " AND created_at >= ?"
# Exclude expired
sql += " AND (expires_at IS NULL OR expires_at > now())"
# Order by recency
sql += " ORDER BY created_at DESC LIMIT ?"
return execute(sql, params)
```
**Strengths:**
- Simple, fast for small datasets
- No dependencies
- Predictable behavior
**Weaknesses:**
- No relevance ranking
- Slow for large datasets (full table scan)
- No fuzzy matching
- No phrase queries or boolean logic
**Performance:** O(n) where n = number of memories
**Target:** <50ms for <500 memories
---
### Phase 2: FTS5 Search
**Algorithm:**
```python
function search_fts5(query, filters):
# Build FTS5 query
fts_query = build_fts5_query(query) # Handles AND/OR/NOT, quotes, prefixes
# FTS5 MATCH with BM25 ranking
sql = """
SELECT m.*, mf.rank as relevance
FROM memories_fts mf
JOIN memories m ON m.id = mf.rowid
WHERE memories_fts MATCH ?
AND (m.expires_at IS NULL OR m.expires_at > now())
"""
# Apply filters (same as Phase 1)
# ...
# Order by FTS5 rank (BM25 algorithm)
sql += " ORDER BY mf.rank LIMIT ?"
return execute(sql, params)
function build_fts5_query(query):
# Transform grep-like to FTS5
# "docker compose" → "docker AND compose"
# "docker OR podman" → "docker OR podman" (unchanged)
# '"exact phrase"' → '"exact phrase"' (unchanged)
# "docker*" → "docker*" (unchanged)
if has_operators(query):
return query
# Implicit AND
terms = query.split()
return " AND ".join(terms)
```
**FTS5 Tokenization:**
- **Tokenizer:** `porter unicode61 remove_diacritics 2`
- **Porter:** Stemming (running → run, databases → database)
- **unicode61:** Unicode support
- **remove_diacritics:** Normalize accented characters (café → cafe)
**BM25 Ranking:**
```
score = Σ(IDF(term) * (f(term) * (k1 + 1)) / (f(term) + k1 * (1 - b + b * |D| / avgdl)))
Where:
- IDF(term) = Inverse Document Frequency (rarer terms score higher)
- f(term) = Term frequency in document
- |D| = Document length
- avgdl = Average document length
- k1 = 1.2 (term frequency saturation)
- b = 0.75 (length normalization)
```
**Strengths:**
- Fast search with inverted index
- Relevance ranking (BM25)
- Boolean operators, phrase queries, prefix matching
- Scales to 100K+ documents
**Weaknesses:**
- No fuzzy matching (typo tolerance)
- FTS5 index overhead (~30% storage)
- More complex setup (triggers needed)
**Performance:** O(log n) for index lookup
**Target:** <100ms for 10K memories
---
### Phase 3: Fuzzy Search
**Algorithm:**
```python
function search_fuzzy(query, filters):
# Step 1: Try FTS5 exact match
results = search_fts5(query, filters)
# Step 2: If too few results, try fuzzy
if len(results) < 5 and filters.fuzzy != false:
fuzzy_results = search_trigram(query, filters)
results = merge_dedup(results, fuzzy_results)
# Step 3: Re-rank by combined score
for result in results:
result.score = calculate_combined_score(result, query)
results.sort(by=lambda r: r.score, reverse=True)
return results[:filters.limit]
function search_trigram(query, threshold=0.7, limit=10):
# Extract query trigrams
query_trigrams = extract_trigrams(query) # ["doc", "ock", "cke", "ker"]
# Find candidates by trigram overlap
sql = """
SELECT m.id, m.content, COUNT(DISTINCT tr.trigram) as matches
FROM memories m
JOIN trigrams tr ON tr.memory_id = m.id
WHERE tr.trigram IN (?, ?, ?, ...)
AND (m.expires_at IS NULL OR m.expires_at > now())
GROUP BY m.id
HAVING matches >= ?
ORDER BY matches DESC
LIMIT ?
"""
min_matches = ceil(len(query_trigrams) * threshold)
candidates = execute(sql, query_trigrams, min_matches, limit * 2)
# Calculate edit distance and combined score
scored = []
for candidate in candidates:
edit_dist = levenshtein(query, candidate.content[:len(query)*3])
trigram_sim = candidate.matches / len(query_trigrams)
normalized_edit = 1 - (edit_dist / max(len(query), len(candidate.content)))
score = 0.6 * trigram_sim + 0.4 * normalized_edit
if score >= threshold:
scored.append((candidate, score))
scored.sort(by=lambda x: x[1], reverse=True)
return [c for c, s in scored[:limit]]
function extract_trigrams(text):
# Normalize: lowercase, remove punctuation, collapse whitespace
normalized = text.lower().replace(/[^\w\s]/g, ' ').replace(/\s+/g, ' ').trim()
# Add padding for boundary matching
padded = " " + normalized + " "
# Sliding window of 3 characters
trigrams = []
for i in range(len(padded) - 2):
trigram = padded[i:i+3]
if trigram.strip().len() == 3: # Skip whitespace-only
trigrams.append(trigram)
return unique(trigrams)
function levenshtein(a, b):
# Wagner-Fischer algorithm with single-row optimization
if len(a) == 0: return len(b)
if len(b) == 0: return len(a)
prev_row = [0..len(b)]
for i in range(len(a)):
cur_row = [i + 1]
for j in range(len(b)):
cost = 0 if a[i] == b[j] else 1
cur_row.append(min(
cur_row[j] + 1, # deletion
prev_row[j + 1] + 1, # insertion
prev_row[j] + cost # substitution
))
prev_row = cur_row
return prev_row[len(b)]
function calculate_combined_score(result, query):
# BM25 from FTS5 (if available)
bm25_score = result.fts_rank if result.has_fts_rank else 0
# Trigram similarity
trigram_score = result.trigram_matches / len(extract_trigrams(query))
# Edit distance (normalized)
edit_dist = levenshtein(query, result.content[:len(query)*3])
edit_score = 1 - (edit_dist / max(len(query), len(result.content)))
# Recency boost (exponential decay over 90 days)
days_ago = (now() - result.created_at) / 86400
recency_score = max(0, 1 - (days_ago / 90))
# Weighted combination
score = (0.4 * bm25_score +
0.3 * trigram_score +
0.2 * edit_score +
0.1 * recency_score)
return score
```
**Trigram Similarity (Jaccard Index):**
```
similarity = |trigrams(query) ∩ trigrams(document)| / |trigrams(query)|
Example:
query = "docker" → trigrams: ["doc", "ock", "cke", "ker"]
document = "dcoker" → trigrams: ["dco", "cok", "oke", "ker"]
intersection = ["ker"] → count = 1
similarity = 1 / 4 = 0.25 (below threshold, but edit distance is 2)
Better approach: Edit distance normalized by length
edit_distance("docker", "dcoker") = 2
normalized = 1 - (2 / 6) = 0.67 (above threshold 0.6)
```
**Strengths:**
- Handles typos (edit distance ≤2)
- Partial matches ("docker" finds "dockerization")
- Cascading strategy (fast exact, fallback to fuzzy)
- Configurable threshold
**Weaknesses:**
- Trigram table is large (~3x content size)
- Slower than FTS5 alone
- Tuning threshold requires experimentation
**Performance:** O(log n) + O(m) where m = trigram candidates
**Target:** <200ms for 10K memories with fuzzy

## Query Processing Flow
### Phase 1 (LIKE)
```
User Query: "docker networking"
│
▼
Parse Query: Extract terms, filters
│
▼
Build SQL: LIKE '%docker%' AND LIKE '%networking%'
│
▼
Apply Filters: Tags, dates, agent
│
▼
Execute: Sequential scan through memories
│
▼
Order: By created_at DESC
│
▼
Limit: Take top N results
│
▼
Format: Plain text / JSON / Markdown
```
### Phase 2 (FTS5)
```
User Query: "docker AND networking"
│
▼
Parse Query: Identify operators, quotes, prefixes
│
▼
Build FTS5 Query: "docker AND networking" (already valid)
│
▼
FTS5 MATCH: Inverted index lookup
│
▼
BM25 Ranking: Calculate relevance scores
│
▼
Apply Filters: Tags, dates, agent (on results)
│
▼
Order: By rank (BM25 score)
│
▼
Limit: Take top N results
│
▼
Format: With relevance scores
```
### Phase 3 (Fuzzy)
```
User Query: "dokcer networking"
│
▼
Try FTS5: "dokcer AND networking"
│
▼
Results: 0 (no exact match)
│
▼
Trigger Fuzzy: Extract trigrams
│
├─▶ "dokcer" → ["dok", "okc", "kce", "cer"]
└─▶ "networking" → ["net", "etw", "two", ...]
│
▼
Find Candidates: Query trigrams table
│
▼
Calculate Similarity: Trigram overlap + edit distance
│
├─▶ "docker" → similarity = 0.85 (good match)
└─▶ "networking" → similarity = 1.0 (exact)
│
▼
Filter: Threshold ≥ 0.7
│
▼
Re-rank: Combined score (trigram + edit + recency)
│
▼
Merge: With FTS5 results (dedup by ID)
│
▼
Limit: Take top N results
│
▼
Format: With relevance scores
```
## Indexing Strategy
### Phase 1 Indexes
```sql
-- Recency queries (ORDER BY created_at DESC)
CREATE INDEX idx_memories_created ON memories(created_at DESC);
-- Expiration filtering (WHERE expires_at > now())
CREATE INDEX idx_memories_expires ON memories(expires_at)
WHERE expires_at IS NOT NULL;
-- Tag lookups (JOIN on tag_id)
CREATE INDEX idx_tags_name ON tags(name);
-- Tag filtering (JOIN memory_tags on memory_id)
CREATE INDEX idx_memory_tags_tag ON memory_tags(tag_id);
```
**Query plans:**
```sql
-- Search query uses indexes:
EXPLAIN QUERY PLAN
SELECT * FROM memories WHERE created_at > ? ORDER BY created_at DESC;
-- Result: SEARCH memories USING INDEX idx_memories_created
EXPLAIN QUERY PLAN
SELECT * FROM memories WHERE expires_at > strftime('%s', 'now');
-- Result: SEARCH memories USING INDEX idx_memories_expires
```
### Phase 2 Indexes (+ FTS5)
```sql
-- FTS5 creates inverted index automatically
CREATE VIRTUAL TABLE memories_fts USING fts5(content, ...);
-- Generates internal tables: memories_fts_data, memories_fts_idx, memories_fts_config
```
**FTS5 Index Structure:**
```
Term → Document Postings List
"docker" → [1, 5, 12, 34, 56, ...]
"compose" → [5, 12, 89, ...]
"networking" → [5, 34, 67, ...]
Query "docker AND compose" → intersection([1,5,12,34,56], [5,12,89]) = [5, 12]
```
### Phase 3 Indexes (+ Trigrams)
```sql
-- Trigram lookups (WHERE trigram IN (...))
CREATE INDEX idx_trigrams_trigram ON trigrams(trigram);
-- Cleanup on memory deletion (CASCADE via memory_id)
CREATE INDEX idx_trigrams_memory ON trigrams(memory_id);
```
**Trigram Index Structure:**
```
Trigram → Memory IDs
"doc" → [1, 5, 12, 34, ...] (all memories with "doc")
"ock" → [1, 5, 12, 34, ...] (all memories with "ock")
"cke" → [1, 5, 12, ...] (all memories with "cke")
Query "docker" trigrams ["doc", "ock", "cke", "ker"]
→ Find intersection: memories with all 4 trigrams (or ≥ threshold)
```
## Performance Optimization
### Database Configuration
```sql
-- WAL mode for better concurrency
PRAGMA journal_mode = WAL;
-- Memory-mapped I/O for faster reads
PRAGMA mmap_size = 268435456; -- 256MB
-- Larger cache for better performance
PRAGMA cache_size = -64000; -- 64MB (negative = KB)
-- Synchronous writes (balance between speed and durability)
PRAGMA synchronous = NORMAL; -- Not FULL (too slow), not OFF (unsafe)
-- Auto-vacuum to prevent bloat
PRAGMA auto_vacuum = INCREMENTAL;
```
### Query Optimization
```javascript
// Use prepared statements (compiled once, executed many times)
const searchStmt = db.prepare(`
SELECT * FROM memories
WHERE LOWER(content) LIKE LOWER(?)
ORDER BY created_at DESC
LIMIT ?
`);
// Transaction for bulk inserts
const insertMany = db.transaction((memories) => {
for (const memory of memories) {
insertStmt.run(memory);
}
});
```
### Trigram Pruning
```javascript
// Prune common trigrams (low information value)
// E.g., "the", "and", "ing" appear in most memories
const pruneCommonTrigrams = db.prepare(`
DELETE FROM trigrams
WHERE trigram IN (
SELECT trigram FROM trigrams
GROUP BY trigram
HAVING COUNT(*) > (SELECT COUNT(*) * 0.5 FROM memories)
)
`);
// Run after bulk imports
pruneCommonTrigrams.run();
```
### Result Caching
```javascript
// LRU cache for frequent queries
const LRU = require('lru-cache');
const queryCache = new LRU({
max: 100, // Cache 100 queries
ttl: 1000 * 60 * 5 // 5 minute TTL
});
function search(query, filters) {
const cacheKey = JSON.stringify({ query, filters });
if (queryCache.has(cacheKey)) {
return queryCache.get(cacheKey);
}
const results = executeSearch(query, filters);
queryCache.set(cacheKey, results);
return results;
}
```
## Error Handling
### Database Errors
```javascript
try {
db.prepare(sql).run(params);
} catch (error) {
if (error.code === 'SQLITE_BUSY') {
// Retry after backoff
await sleep(100);
return retry(operation, maxRetries - 1);
}
if (error.code === 'SQLITE_CONSTRAINT') {
// Validation error (content too long, duplicate tag, etc.)
throw new ValidationError(error.message);
}
if (error.code === 'SQLITE_CORRUPT') {
// Database corruption - suggest recovery
throw new DatabaseCorruptError('Database corrupted, run: memory recover');
}
// Unknown error
throw error;
}
```
### Migration Errors
```javascript
async function migrate(targetVersion) {
const currentVersion = getCurrentSchemaVersion();
// Backup before migration
await backupDatabase(`backup-v${currentVersion}.db`);
try {
db.exec('BEGIN TRANSACTION');
// Run migrations
for (let v = currentVersion + 1; v <= targetVersion; v++) {
await runMigration(v);
}
db.exec('COMMIT');
console.log(`Migrated to version ${targetVersion}`);
} catch (error) {
db.exec('ROLLBACK');
console.error('Migration failed, rolling back');
// Restore backup
await restoreDatabase(`backup-v${currentVersion}.db`);
throw error;
}
}
```
## Security Considerations
### Input Validation
```javascript
// Prevent SQL injection (prepared statements)
const stmt = db.prepare('SELECT * FROM memories WHERE content LIKE ?');
stmt.all(`%${userInput}%`); // Safe: userInput is parameterized
// Validate content length
if (content.length > 10000) {
throw new ValidationError('Content exceeds 10KB limit');
}
// Sanitize tags (only alphanumeric, hyphens, underscores)
const sanitizeTag = (tag) => tag.replace(/[^a-z0-9\-_]/gi, '');
```
### Sensitive Data Protection
```javascript
// Warn if sensitive patterns detected
const sensitivePatterns = [
/password\s*[:=]\s*\S+/i,
/api[_-]?key\s*[:=]\s*\S+/i,
/token\s*[:=]\s*\S+/i,
/secret\s*[:=]\s*\S+/i
];
function checkSensitiveData(content) {
for (const pattern of sensitivePatterns) {
if (pattern.test(content)) {
console.warn('⚠️ Warning: Potential sensitive data detected');
console.warn('Consider storing credentials in a secure vault instead');
return true;
}
}
return false;
}
```
### File Permissions
```bash
# Database file should be user-readable only
chmod 600 ~/.config/opencode/memories.db
# Backup files should have same permissions
chmod 600 ~/.config/opencode/memories-backup-*.db
```
## Scalability Limits
### Phase 1 (LIKE)
- **Max memories:** ~500 (performance degrades beyond)
- **Query latency:** O(n) - linear scan
- **Storage:** ~250KB for 500 memories
### Phase 2 (FTS5)
- **Max memories:** ~50K (comfortable), 100K+ (possible)
- **Query latency:** O(log n) - index lookup
- **Storage:** +30% for FTS5 index (~325KB for 500 memories)
### Phase 3 (Fuzzy)
- **Max memories:** 100K+ (with trigram pruning)
- **Query latency:** O(log n) + O(m) where m = fuzzy candidates
- **Storage:** +200% for trigrams (~750KB for 500 memories)
- Mitigated by pruning common trigrams
### Migration Triggers
**Phase 1 → Phase 2:**
- Dataset > 500 memories
- Query latency > 500ms
- Manual user request
**Phase 2 → Phase 3:**
- User reports needing fuzzy search
- High typo rates in queries
- Manual user request
## Future Enhancements
### Vector Embeddings (Phase 4?)
- Semantic search ("docker" → "containerization")
- Requires embedding model (~100MB)
- SQLite-VSS extension
- Hybrid: BM25 (lexical) + Cosine similarity (semantic)
### Automatic Summarization
- LLM-generated summaries for long memories
- Reduces token usage in search results
- Trade-off: API dependency
### Memory Versioning
- Track edits to memories
- Show history
- Revert to previous version
### Conflict Detection
- Identify contradictory memories
- Suggest consolidation
- Flag for review
### Collaborative Features
- Share memories between agents
- Team-wide memory pool
- Privacy controls

**Tests:** 9/9 passing (in integration tests)
- Full workflow (store → search → list → prune)
- Performance (<50ms for 100 memories)
- <1 second to store 100 memories
- Edge cases (empty query, special chars, unicode, long tags)
## Test Summary
```
✓ Database Layer (13 tests)
✓ Schema Initialization (7 tests)
✓ Connection Management (6 tests)
✓ Store Command (8 tests)
✓ Basic storage with tags
✓ Validation (10KB limit, empty content, future expiration)
✓ Tag handling (normalization, deduplication)
✓ Search Command (9 tests)
✓ Content search (case-insensitive)
✓ Filtering (tags AND/OR, dates, agent)
✓ Automatic expiration exclusion
✓ Sorting and pagination
✓ Integration Tests (9 tests)
✓ Full workflows (store → search → list → prune)
✓ Performance targets met
✓ Edge cases handled
Total: 39/39 tests passing (100%)
Duration: ~100ms
```
## Performance Results
**Phase 1 Targets:**
- ✅ Search 100 memories: <50ms (actual: ~20-30ms)
- ✅ Store 100 memories: <1000ms (actual: ~200-400ms)
- ✅ Database size: Minimal with indexes
## TDD Approach Validation
**Workflow:**
1. ✅ Wrote tests first (.todo() → real tests)
2. ✅ Watched tests fail (red)
3. ✅ Implemented features
4. ✅ Watched tests pass (green)
5. ✅ Refactored based on failures
**Benefits Observed:**
- Caught CHECK constraint issues immediately
- Found validation edge cases early
- Performance testing built-in from start
- Clear success criteria for each feature
## Known Limitations & Notes
### WAL Mode in :memory: Databases
- In-memory SQLite returns 'memory' instead of 'wal' for journal_mode
- This is expected behavior and doesn't affect functionality
- File-based databases will correctly use WAL mode
### Check Constraints
- Schema enforces `expires_at > created_at`
- Tests work around this by setting both timestamps
- Real usage won't hit this (expires always in future)
## What's NOT Implemented (Future Phases)
### Phase 2 (FTS5)
- [ ] FTS5 virtual table
- [ ] BM25 relevance ranking
- [ ] Boolean operators (AND/OR/NOT in query syntax)
- [ ] Phrase queries with quotes
- [ ] Migration script
### Phase 3 (Fuzzy)
- [ ] Trigram indexing
- [ ] Levenshtein distance
- [ ] Intelligent cascade (exact → fuzzy)
- [ ] Combined relevance scoring
### CLI Integration
- [x] Connect CLI to commands (src/cli.js fully wired)
- [x] Output formatting (plain text, JSON, markdown)
- [x] Colors with chalk
- [x] Global installation (bin/memory shim)
- [x] OpenCode plugin integration (plugin/llmemory.js)
### Additional Features
- [x] Stats command (with --tags and --agents options)
- [x] Agent context documentation (--agent-context)
- [ ] Export/import commands (Phase 2)
- [ ] Auto-extraction (*Remember* pattern) (Phase 2)
## Next Steps
### Immediate (Complete MVP)
1. **Wire up CLI to commands** (Step 1.7)
- Replace placeholder commands with real implementations
- Add output formatting
- Test end-to-end CLI workflow
2. **Manual Testing**
```bash
node src/cli.js store "Docker uses bridge networks" --tags docker
node src/cli.js search "docker"
node src/cli.js list --limit 5
```
### Future Phases
- Phase 2: FTS5 when dataset > 500 memories
- Phase 3: Fuzzy when typo tolerance needed
- OpenCode plugin integration
- Agent documentation

# TDD Testing Philosophy - Added to LLMemory
## What Was Updated
### 1. Updated IMPLEMENTATION_PLAN.md
- ✅ Rewrote testing strategy section with integration-first philosophy
- ✅ Added TDD workflow to Steps 1.3 (Store) and 1.4 (Search)
- ✅ Each step now has "write test first" as explicit requirement
- ✅ Test code examples included before implementation examples
### 2. Updated AGENTS.md
- ⚠️ File doesn't exist in opencode root, skipped
- Created TESTING.md instead with full testing guide
### 3. Created docs/TESTING.md
- ✅ Comprehensive testing philosophy document
- ✅ TDD workflow with detailed examples
- ✅ Integration-first approach explained
- ✅ When to write unit tests (rarely!)
- ✅ Realistic data seeding strategies
- ✅ Watch-driven development workflow
- ✅ Good vs bad test examples
### 4. Created test/integration.test.js
- ✅ Test structure scaffolded with `.todo()` markers
- ✅ Shows TDD structure before implementation
- ✅ Database layer tests
- ✅ Store command tests
- ✅ Search command tests
- ✅ Performance tests
- ✅ Edge case tests
### 5. Simplified Dependencies
- ⚠️ Removed `better-sqlite3` temporarily (build issues on NixOS)
- ✅ Installed: commander, chalk, date-fns, vitest
- ✅ Tests run successfully (all `.todo()` so pass by default)
## Current Status
**Tests Setup:** ✅ Complete
```bash
npm test # Runs all tests (currently 0 real tests, 30+ .todo())
npm run test:watch # Watch mode for TDD workflow
```
**Next Steps (TDD Approach):**
1. **Install better-sqlite3** (need native build tools)
```bash
# On NixOS, may need: nix-shell -p gcc gnumake python3
npm install better-sqlite3
```
2. **Write First Real Test** (database schema)
```javascript
test('creates memories table with correct schema', () => {
const db = new Database(':memory:');
initSchema(db);
const tables = db.prepare("SELECT name FROM sqlite_master WHERE type='table'").all();
expect(tables.map(t => t.name)).toContain('memories');
});
```
3. **Watch Test Fail** (`npm run test:watch`)
4. **Implement** (src/db/schema.js)
5. **Watch Test Pass**
6. **Move to Next Test**
## TDD Philosophy Summary
**DO:**
- ✅ Write integration tests first
- ✅ Use realistic data (50-100 memories)
- ✅ Test with `:memory:` or temp file database
- ✅ Run in watch mode
- ✅ See test fail → implement → see test pass
**DON'T:**
- ❌ Write unit tests for simple functions
- ❌ Test implementation details
- ❌ Use toy data (1-2 memories)
- ❌ Mock the database (test the real thing)
## Build Issue Note
`better-sqlite3` requires native compilation. On NixOS:
```bash
# Option 1: Use nix-shell
nix-shell -p gcc gnumake python3
npm install better-sqlite3
# Option 2: Use in-memory mock for testing
# Implement with native SQLite later
```
This is documented in test/integration.test.js comments.
## Next Session Reminder
Start with: `/home/nate/nixos/shared/linked-dotfiles/opencode/llmemory/`
1. Fix better-sqlite3 installation
2. Remove `.todo()` from first test
3. Watch it fail
4. Implement schema.js
5. Watch it pass
6. Continue with TDD approach
All tests are scaffolded and ready!

# LLMemory Testing Guide
## Testing Philosophy: Integration-First TDD
This project uses **integration-first TDD** - we write integration tests that verify real workflows, not unit tests that verify implementation details.
## Core Principles
### 1. Integration Tests Are Primary
**Why:**
- Tests real behavior users/agents will experience
- Less brittle (survives refactoring)
- Higher confidence in system working correctly
- Catches integration issues early
**Example:**
```javascript
// GOOD: Integration test
test('store and search workflow', () => {
// Test the actual workflow
storeMemory(db, { content: 'Docker uses bridge networks', tags: 'docker' });
const results = searchMemories(db, 'docker');
expect(results[0].content).toContain('Docker');
});
// AVOID: Over-testing implementation details
test('parseContent returns trimmed string', () => {
expect(parseContent(' test ')).toBe('test');
});
// ^ This is probably already tested by integration tests
```
### 2. Unit Tests Are Rare
**Only write unit tests for:**
- Complex algorithms (Levenshtein distance, trigram extraction)
- Pure functions with many edge cases
- Critical validation logic
**Don't write unit tests for:**
- Database queries (test via integration)
- CLI argument parsing (test via integration)
- Simple utilities (tag parsing, date formatting)
- Anything already covered by integration tests
**Rule of thumb:** Think twice before writing a unit test. Ask: "Is this already tested by my integration tests?"
### 3. Test With Realistic Data
**Use real SQLite databases:**
```javascript
beforeEach(() => {
db = new Database(':memory:'); // Fast, isolated
initSchema(db);
// Seed with realistic data
seedDatabase(db, 50); // 50 realistic memories
});
```
**Generate realistic test data:**
```javascript
// test/helpers/seed.js
export function generateRealisticMemory() {
const templates = [
{ content: 'Docker Compose requires explicit subnet config', tags: ['docker', 'networking'] },
{ content: 'PostgreSQL VACUUM FULL locks tables', tags: ['postgresql', 'performance'] },
{ content: 'Git worktree allows parallel branches', tags: ['git', 'workflow'] },
// 50+ realistic templates
];
return randomChoice(templates);
}
```
**Why:** Tests should reflect real usage, not artificial toy data.
### 4. Watch-Driven Development
**Workflow:**
```bash
# Terminal 1: Watch mode (always running)
npm run test:watch
# Terminal 2: Manual testing
node src/cli.js store "test memory"
```
**Steps:**
1. Write integration test (red/failing)
2. Watch test fail
3. Implement feature
4. Watch test pass (green)
5. Verify manually with CLI
6. Refine based on output
## TDD Workflow Example
### Example: Implementing Store Command
**Step 1: Write Test First**
```javascript
// test/integration.test.js
describe('Store Command', () => {
let db;
beforeEach(() => {
db = new Database(':memory:');
initSchema(db);
});
test('stores memory with tags', () => {
const result = storeMemory(db, {
content: 'Docker uses bridge networks',
tags: 'docker,networking'
});
expect(result.id).toBeDefined();
// Verify in database
const memory = db.prepare('SELECT * FROM memories WHERE id = ?').get(result.id);
expect(memory.content).toBe('Docker uses bridge networks');
// Verify tags linked correctly
const tags = db.prepare(`
SELECT t.name FROM tags t
JOIN memory_tags mt ON t.id = mt.tag_id
WHERE mt.memory_id = ?
`).all(result.id);
expect(tags.map(t => t.name)).toEqual(['docker', 'networking']);
});
test('rejects content over 10KB', () => {
expect(() => {
storeMemory(db, { content: 'x'.repeat(10001) });
}).toThrow('Content exceeds 10KB limit');
});
});
```
**Step 2: Run Test (Watch It Fail)**
```bash
$ npm run test:watch
FAIL test/integration.test.js
Store Command
✕ stores memory with tags (2 ms)
✕ rejects content over 10KB (1 ms)
● Store Command › stores memory with tags
ReferenceError: storeMemory is not defined
```
**Step 3: Implement Feature**
```javascript
// src/commands/store.js
export function storeMemory(db, { content, tags, expires, entered_by }) {
// Validate content
if (content.length > 10000) {
throw new Error('Content exceeds 10KB limit');
}
// Insert memory
const result = db.prepare(`
INSERT INTO memories (content, entered_by, expires_at)
VALUES (?, ?, ?)
`).run(content, entered_by, expires);
// Handle tags
if (tags) {
const tagList = tags.split(',').map(t => t.trim().toLowerCase());
linkTags(db, result.lastInsertRowid, tagList);
}
return { id: result.lastInsertRowid };
}
```
**Step 4: Watch Test Pass**
```bash
PASS test/integration.test.js
Store Command
✓ stores memory with tags (15 ms)
✓ rejects content over 10KB (3 ms)
Tests: 2 passed, 2 total
```
**Step 5: Verify Manually**
```bash
$ node src/cli.js store "Docker uses bridge networks" --tags docker,networking
Memory #1 stored successfully
$ node src/cli.js search "docker"
[2025-10-29 12:45] docker, networking
Docker uses bridge networks
```
**Step 6: Refine**
```javascript
// Add more test cases based on manual testing
test('normalizes tags to lowercase', () => {
storeMemory(db, { content: 'test', tags: 'Docker,NETWORKING' });
const tags = db.prepare('SELECT name FROM tags').all();
expect(tags).toEqual([
{ name: 'docker' },
{ name: 'networking' }
]);
});
```

### Integration Test Structure
```javascript
// test/integration.test.js
import { describe, test, expect, beforeEach, afterEach } from 'vitest';
import Database from 'better-sqlite3';
import { storeMemory, searchMemories } from '../src/commands/index.js';
import { initSchema } from '../src/db/schema.js';
import { seedDatabase } from './helpers/seed.js';
describe('Memory System Integration', () => {
let db;
beforeEach(() => {
db = new Database(':memory:');
initSchema(db);
});
afterEach(() => {
db.close();
});
describe('Store and Retrieve', () => {
test('stores and finds memory', () => {
storeMemory(db, { content: 'test', tags: 'demo' });
const results = searchMemories(db, 'test');
expect(results).toHaveLength(1);
});
});
describe('Search with Filters', () => {
beforeEach(() => {
seedDatabase(db, 50); // Realistic data
});
test('filters by tags', () => {
const results = searchMemories(db, 'docker', { tags: ['networking'] });
results.forEach(r => {
expect(r.tags).toContain('networking');
});
});
});
describe('Performance', () => {
test('searches 100 memories in <50ms', () => {
seedDatabase(db, 100);
const start = Date.now();
searchMemories(db, 'test');
const duration = Date.now() - start;
expect(duration).toBeLessThan(50);
});
});
});
```
## Unit Test Structure (Rare)
**Only for complex algorithms:**
```javascript
// test/unit/levenshtein.test.js
import { describe, test, expect } from 'vitest';
import { levenshtein } from '../../src/search/fuzzy.js';
describe('Levenshtein Distance', () => {
test('calculates edit distance correctly', () => {
expect(levenshtein('docker', 'dcoker')).toBe(2);
expect(levenshtein('kubernetes', 'kuberntes')).toBe(2);
expect(levenshtein('same', 'same')).toBe(0);
});
test('handles edge cases', () => {
expect(levenshtein('', 'hello')).toBe(5);
expect(levenshtein('a', '')).toBe(1);
expect(levenshtein('', '')).toBe(0);
});
test('handles unicode correctly', () => {
expect(levenshtein('café', 'cafe')).toBe(1);
});
});
```
## Test Data Helpers
### Realistic Memory Generation
```javascript
// test/helpers/seed.js
const REALISTIC_MEMORIES = [
{ content: 'Docker Compose uses bridge networks by default. Custom networks require explicit subnet config.', tags: ['docker', 'networking'] },
{ content: 'PostgreSQL VACUUM FULL locks tables and requires 2x disk space. Use VACUUM ANALYZE for production.', tags: ['postgresql', 'performance'] },
{ content: 'Git worktree allows working on multiple branches without stashing. Use: git worktree add ../branch branch-name', tags: ['git', 'workflow'] },
{ content: 'NixOS flake.lock must be committed to git for reproducible builds across machines', tags: ['nixos', 'build-system'] },
{ content: 'TypeScript 5.0+ const type parameters preserve literal types: function id<const T>(x: T): T', tags: ['typescript', 'types'] },
// ... 50+ more realistic examples
];
export function generateRealisticMemory() {
return { ...randomChoice(REALISTIC_MEMORIES) };
}
export function seedDatabase(db, count = 50) {
const insert = db.prepare(`
INSERT INTO memories (content, entered_by, created_at)
VALUES (?, ?, ?)
`);
const insertMany = db.transaction((memories) => {
for (const memory of memories) {
const result = insert.run(
memory.content,
randomChoice(['investigate-agent', 'optimize-agent', 'manual']),
Date.now() - randomInt(0, 90 * 86400000) // Random within 90 days
);
// Link tags
if (memory.tags) {
linkTags(db, result.lastInsertRowid, memory.tags);
}
}
});
const memories = Array.from({ length: count }, () => generateRealisticMemory());
insertMany(memories);
}
function randomChoice(arr) {
return arr[Math.floor(Math.random() * arr.length)];
}
function randomInt(min, max) {
return Math.floor(Math.random() * (max - min + 1)) + min;
}
```
## Running Tests
```bash
# Watch mode (primary workflow)
npm run test:watch
# Run once
npm test
# With coverage
npm run test:coverage
# Specific test file
npm test integration.test.js
# Run in CI (no watch)
npm test -- --run
```
## Coverage Guidelines
**Target: >80% coverage, but favor integration over unit**
**What to measure:**
- Are all major workflows tested? (store, search, list, prune)
- Are edge cases covered? (empty data, expired memories, invalid input)
- Are performance targets met? (<50ms search for Phase 1)
**What NOT to obsess over:**
- 100% line coverage (diminishing returns)
- Testing every internal function (if covered by integration tests)
- Testing framework code (CLI parsing, DB driver)
**Check coverage:**
```bash
npm run test:coverage
# View HTML report
open coverage/index.html
```
## Examples of Good vs Bad Tests
### ✅ Good: Integration Test
```javascript
test('full workflow: store, search, list, prune', () => {
// Store memories
storeMemory(db, { content: 'Memory 1', tags: 'test' });
storeMemory(db, { content: 'Memory 2', tags: 'test', expires_at: Date.now() - 1000 });
// Search finds active memory
const results = searchMemories(db, 'Memory');
expect(results).toHaveLength(2); // Both found initially
// List shows both
const all = listMemories(db);
expect(all).toHaveLength(2);
// Prune removes expired
const pruned = pruneMemories(db);
expect(pruned.count).toBe(1);
// Search now finds only active
const afterPrune = searchMemories(db, 'Memory');
expect(afterPrune).toHaveLength(1);
});
```
### ❌ Bad: Over-Testing Implementation
```javascript
// AVOID: Testing internal implementation details
test('parseTagString splits on comma', () => {
expect(parseTagString('a,b,c')).toEqual(['a', 'b', 'c']);
});
test('normalizeTag converts to lowercase', () => {
expect(normalizeTag('Docker')).toBe('docker');
});
// These are implementation details already covered by integration tests!
```
### ✅ Good: Unit Test (Justified)
```javascript
// Complex algorithm worth isolated testing
test('levenshtein distance edge cases', () => {
// Empty strings
expect(levenshtein('', '')).toBe(0);
expect(levenshtein('abc', '')).toBe(3);
// Unicode
expect(levenshtein('café', 'cafe')).toBe(1);
// Long strings
const long1 = 'a'.repeat(1000);
const long2 = 'a'.repeat(999) + 'b';
expect(levenshtein(long1, long2)).toBe(1);
});
```
## Debugging Failed Tests
### 1. Use `.only` to Focus
```javascript
test.only('this specific test', () => {
// Only runs this test
});
```
### 2. Inspect Database State
```javascript
test('debug search', () => {
storeMemory(db, { content: 'test' });
// Inspect what's in DB
const all = db.prepare('SELECT * FROM memories').all();
console.log('Database contents:', all);
const results = searchMemories(db, 'test');
console.log('Search results:', results);
expect(results).toHaveLength(1);
});
```
### 3. Use Temp File for Manual Inspection
```javascript
test('debug with file', () => {
const db = new Database('/tmp/debug.db');
initSchema(db);
storeMemory(db, { content: 'test' });
// Now inspect with: sqlite3 /tmp/debug.db
});
```
## Summary
**DO:**
- ✅ Write integration tests for all workflows
- ✅ Use realistic data (50-100 memories)
- ✅ Test with `:memory:` database
- ✅ Run in watch mode (`npm run test:watch`)
- ✅ Verify manually with CLI after tests pass
- ✅ Think twice before writing unit tests
**DON'T:**
- ❌ Test implementation details
- ❌ Write unit tests for simple functions
- ❌ Use toy data (1-2 memories)
- ❌ Mock database or CLI (test the real thing)
- ❌ Aim for 100% coverage at expense of test quality
**Remember:** Integration tests that verify real workflows are worth more than 100 unit tests that verify implementation details.
---
**Testing Philosophy:** Integration-first TDD with realistic data
**Coverage Target:** >80% (mostly integration tests)
**Unit Tests:** Rare, only for complex algorithms
**Workflow:** Write test (fail) → Implement (pass) → Verify (manual) → Refine

**SKILL NAME:** ${skill.name}
**SKILL DIRECTORY:** ${skill.fullPath}/
## EXECUTION WORKFLOW:
**STEP 1: PLAN THE WORK**
Before executing this skill, use the \`todowrite\` tool to create a todo list of the main tasks described in the skill content below.
- Parse the skill instructions carefully
- Identify the key tasks and steps required
- Create todos with status "pending" and appropriate priority levels
- This helps track progress and ensures nothing is missed
**STEP 2: EXECUTE THE SKILL**
Follow the skill instructions below, marking todos as "in_progress" when starting a task and "completed" when done.
Use \`todowrite\` to update task statuses as you work through them.
## PATH RESOLUTION RULES (READ CAREFULLY):
All file paths mentioned below are relative to the SKILL DIRECTORY shown above.
**Examples:**
- If the skill mentions \`scripts/init_skill.py\`, the full path is: \`${skill.fullPath}/scripts/init_skill.py\`
- If the skill mentions \`references/docs.md\`, the full path is: \`${skill.fullPath}/references/docs.md\`
- If the skill mentions \`assets/template.html\`, the full path is: \`${skill.fullPath}/assets/template.html\`
**IMPORTANT:** Always prepend \`${skill.fullPath}/\` to any relative path mentioned in the skill content below.
---
# SKILL CONTENT:
${skill.content}
---
**Remember:**
1. All relative paths in the skill content above are relative to: \`${skill.fullPath}/\`
2. Update your todo list as you progress through the skill tasks

name: create-skill
description: Use when creating new skills, editing existing skills, or planning skill architecture - provides comprehensive guidance on skill structure, discoverability, token efficiency, and best practices for writing skills that AI can find and use effectively
---
# Creating Skills
## Overview
Skills are reference guides for proven techniques, patterns, or tools. Good skills are concise, well-structured, discoverable, and help AI instances find and apply effective approaches.
**Core principle:** Only add context AI doesn't already have. Challenge every token - assume Claude is smart and knows standard practices.
## When to Create a Skill
**Create when:**
- Technique wasn't intuitively obvious to you
- You'd reference this again across projects
- Pattern applies broadly (not project-specific)
- Others would benefit from this knowledge
**Don't create for:**
- One-off solutions
- Standard practices well-documented elsewhere
- Project-specific conventions (put in CLAUDE.md instead)
- Obvious or trivial information
## Skill Types
### Technique
Concrete method with steps to follow
**Examples:** condition-based-waiting, root-cause-tracing, defensive-programming
**Test with:** Application scenarios, variation scenarios, missing information tests
### Pattern
Way of thinking about problems
**Examples:** flatten-with-flags, reducing-complexity, information-hiding
**Test with:** Recognition scenarios, application scenarios, counter-examples
### Reference
API docs, syntax guides, tool documentation
**Examples:** API documentation, command references, library guides
**Test with:** Retrieval scenarios, application scenarios, gap testing
## Skill Structure Requirements
### Directory Layout
```
skill-name/
├── SKILL.md # Required: Main skill file with frontmatter
├── scripts/ # Optional: Executable code
├── references/ # Optional: Documentation to load as needed
└── assets/ # Optional: Files used in output
```
### Naming Conventions
- **Directory name**: lowercase with hyphens only (e.g., `my-skill`)
- **Frontmatter name**: must exactly match directory name
- **Skill access**: Skills are loaded via the `learn_skill` tool with the skill name as an argument
- **Use gerund form (verb + -ing)**: `processing-pdfs`, `analyzing-data`, `creating-skills`
- **Avoid vague names**: "Helper", "Utils", "Tools"
## Frontmatter Requirements
### Required Fields
```yaml
---
name: skill-name
description: Use when [specific triggers/symptoms] - [what it does and how it helps]
---
```
### Constraints
- **Max 1024 characters total** for frontmatter
- **Only `name` and `description`** fields supported
- **Name**: letters, numbers, hyphens only (no parentheses, special chars)
- **Description target**: under 500 characters if possible
### Writing Effective Descriptions
**Critical for discovery:** AI reads description to decide which skills to load.
**Format:** Start with "Use when..." to focus on triggering conditions
**Include:**
- Concrete triggers, symptoms, and situations that signal this skill applies
- Describe the *problem* not *language-specific symptoms* (unless skill is tech-specific)
- Technology-agnostic triggers unless skill is technology-specific
- What the skill does and how it helps
**Always write in third person** (injected into system prompt):
**Good examples:**
```yaml
description: Use when tests have race conditions, timing dependencies, or pass/fail inconsistently - replaces arbitrary timeouts with condition polling for reliable async tests
description: Use when using React Router and handling authentication redirects - provides patterns for protected routes and auth state management
description: Extract text and tables from PDF files, fill forms, merge documents. Use when working with PDF files or when the user mentions PDFs, forms, or document extraction.
```
**Bad examples:**
```yaml
# Too abstract, no triggers
description: For async testing
# First person
description: I can help you with async tests when they're flaky
# Vague, no specifics
description: Helps with documents
```
## Core Principles
### Concise is Key
Context window is shared with everything else. Only add what AI doesn't already know.
**Challenge each piece of information:**
- "Does Claude really need this explanation?"
- "Can I assume Claude knows this?"
- "Does this paragraph justify its token cost?"
**Good (concise - ~50 tokens):**
````markdown
## Extract PDF text
Use pdfplumber for text extraction:
```python
import pdfplumber
with pdfplumber.open("file.pdf") as pdf:
text = pdf.pages[0].extract_text()
```
````
**Bad (verbose - ~150 tokens):**
```markdown
## Extract PDF text
PDF (Portable Document Format) files are a common file format that contains text, images, and other content. To extract text from a PDF, you'll need to use a library. There are many libraries available for PDF processing, but we recommend pdfplumber because it's easy to use and handles most cases well. First, you'll need to install it using pip. Then you can use the code below...
```
### Set Appropriate Degrees of Freedom
Match specificity to task fragility and variability.
**Analogy:** Think of AI as a robot exploring a path:
- **Narrow bridge with cliffs**: Provide specific guardrails and exact instructions (low freedom)
- **Open field with no hazards**: Give general direction and trust AI to find best route (high freedom)
**High freedom** (text-based instructions):
Use when multiple approaches are valid, decisions depend on context, heuristics guide approach.
```markdown
## Code review process
1. Analyze the code structure and organization
2. Check for potential bugs or edge cases
3. Suggest improvements for readability and maintainability
4. Verify adherence to project conventions
```
**Medium freedom** (pseudocode or scripts with parameters):
Use when a preferred pattern exists, some variation is acceptable, configuration affects behavior.
````markdown
## Generate report
Use this template and customize as needed:
```python
def generate_report(data, format="markdown", include_charts=True):
# Process data
# Generate output in specified format
# Optionally include visualizations
```
````
**Low freedom** (specific scripts, few or no parameters):
Use when operations are fragile and error-prone, consistency is critical, specific sequence must be followed.
````markdown
## Database migration
Run exactly this script:
```bash
python scripts/migrate.py --verify --backup
```
Do not modify the command or add additional flags.
````
## Content Structure
### Recommended Template
```markdown
# Skill Title
Brief overview of the skill's purpose (1-2 sentences with core principle).
## When to Use This Skill
List specific symptoms and use cases:
- Use case 1
- Use case 2
**When NOT to use:**
- Counter-example 1
- Counter-example 2
## Core Pattern (for techniques/patterns)
Before/after code comparison OR quick reference table for scanning
## Quick Reference
Table or bullets for common operations
## Implementation
Step-by-step guidance (inline for simple, link to files for complex)
## Common Mistakes
What goes wrong + fixes
## Real-World Impact (optional)
Concrete results showing effectiveness
```
### Progressive Disclosure
SKILL.md serves as overview that points to detailed materials as needed.
**Keep SKILL.md under 500 lines for optimal performance**
**Pattern 1: High-level guide with references**

**API reference**: See `references/api.md` for all methods
**Examples**: See `references/examples.md` for common patterns
````
**Pattern 2: Domain-specific organization**
Keep token usage low by organizing content so AI loads only relevant domains.
```
bigquery-skill/
├── SKILL.md (overview and navigation)
└── references/
├── finance.md (revenue, billing metrics)
├── sales.md (opportunities, pipeline)
├── product.md (API usage, features)
└── marketing.md (campaigns, attribution)
```
**Pattern 3: Conditional details**
Show basic content inline, link to advanced content:
```markdown
# DOCX Processing
## Creating documents
Use docx-js for new documents. See `references/docx-js.md`.
## Editing documents
For simple edits, modify the XML directly.
**For tracked changes**: See `references/redlining.md`
**For OOXML details**: See `references/ooxml.md`
```
**Avoid deeply nested references** - keep all reference files one level deep from SKILL.md. AI may partially read nested files, resulting in incomplete information.
**Table of contents for long references** - Files >100 lines need TOC at top to enable previewing scope.
## Skill Discovery Optimization
Future AI needs to FIND your skill. Optimize for discovery.
### Keyword Coverage
Use words AI would search for:
- **Error messages**: "Hook timed out", "ENOTEMPTY", "race condition"
- **Symptoms**: "flaky", "hanging", "zombie", "pollution"
- **Synonyms**: "timeout/hang/freeze", "cleanup/teardown/afterEach"
- **Tools**: Actual commands, library names, file types
### Descriptive Naming
**Use active voice, verb-first (gerund form):**
- ✅ `creating-skills` not `skill-creation`
- ✅ `testing-async-code` not `async-test-helpers`
- ✅ `processing-pdfs` not `pdf-processor`
### Token Efficiency
**Target word counts:**
- Getting-started workflows: <150 words each
- Frequently-loaded skills: <200 words total
- Other skills: <500 words (still be concise)
**Techniques:**
**Move details to tool help:**
```bash
# ❌ BAD: Document all flags in SKILL.md
search-conversations supports --text, --both, --after DATE, --before DATE, --limit N
# ✅ GOOD: Reference --help
search-conversations supports multiple modes and filters. Run --help for details.
```
**Use cross-references:**
```markdown
# ❌ BAD: Repeat workflow details
When searching, dispatch subagent with template...
[20 lines of repeated instructions]
# ✅ GOOD: Reference other skill
Always use subagents (50-100x context savings). Use skill-name for workflow.
```
**Compress examples:**
```markdown
# ❌ BAD: Verbose (42 words)
your human partner: "How did we handle authentication errors in React Router before?"
You: I'll search past conversations for React Router authentication patterns.
[Dispatch subagent with search query: "React Router authentication error handling 401"]
# ✅ GOOD: Minimal (20 words)
Partner: "How did we handle auth errors in React Router?"
You: Searching...
[Dispatch subagent → synthesis]
```
**Verification:**
```bash
wc -w skills/path/SKILL.md
```
### Cross-Referencing Other Skills
Use skill name only, with explicit requirement markers:
- ✅ Good: `**REQUIRED:** Use skill-name-here`
- ✅ Good: `**REQUIRED BACKGROUND:** You MUST understand skill-name-here`
- ❌ Bad: `See skills/testing/test-driven-development` (unclear if required)
**Why no @ links:** Force-loads files immediately, consuming context before needed.
### Discovery Workflow
How AI finds and uses your skill:
1. **Encounters problem** ("tests are flaky")
2. **Searches descriptions** (keyword matching)
3. **Finds SKILL** (description matches symptoms)
4. **Scans overview** (is this relevant?)
5. **Reads patterns** (quick reference table)
6. **Loads example** (only when implementing)
**Optimize for this flow** - put searchable terms early and often.
## Workflows and Feedback Loops
### Use Workflows for Complex Tasks
Break complex operations into clear, sequential steps. Provide checklists AI can copy and check off.
**Example 1: Research synthesis workflow** (no code):
````markdown
## Research synthesis workflow
Copy this checklist and track your progress:
```
Research Progress:
- [ ] Step 1: Read all source documents
- [ ] Step 2: Identify key themes
- [ ] Step 3: Cross-reference claims
- [ ] Step 4: Create structured summary
- [ ] Step 5: Verify citations
```
**Step 1: Read all source documents**
Review each document in the `sources/` directory. Note the main arguments and supporting evidence.
**Step 2: Identify key themes**
Look for patterns across sources. What themes appear repeatedly? Where do sources agree or disagree?
[Continue with detailed steps...]
````
**Example 2: PDF form filling workflow** (with code):
````markdown
## PDF form filling workflow
Copy this checklist and check off items as you complete them:
```
Task Progress:
- [ ] Step 1: Analyze the form (run analyze_form.py)
- [ ] Step 2: Create field mapping (edit fields.json)
- [ ] Step 3: Validate mapping (run validate_fields.py)
- [ ] Step 4: Fill the form (run fill_form.py)
- [ ] Step 5: Verify output (run verify_output.py)
```
**Step 1: Analyze the form**
Run: `python scripts/analyze_form.py input.pdf`
[Continue with detailed steps...]
````
### Implement Feedback Loops
**Common pattern:** Run validator → fix errors → repeat
**Example: Document editing process**
```markdown
## Document editing process
1. Make your edits to `word/document.xml`
2. **Validate immediately**: `python ooxml/scripts/validate.py unpacked_dir/`
3. If validation fails:
- Review the error message carefully
- Fix the issues in the XML
- Run validation again
4. **Only proceed when validation passes**
5. Rebuild: `python ooxml/scripts/pack.py unpacked_dir/ output.docx`
6. Test the output document
```
## Code Examples
**One excellent example beats many mediocre ones**
Choose most relevant language:
- Testing techniques → TypeScript/JavaScript
- System debugging → Shell/Python
- Data processing → Python
**Good example characteristics:**
- Complete and runnable
- Well-commented explaining WHY
- From real scenario
- Shows pattern clearly
- Ready to adapt (not generic template)
**Don't:**
- Implement in 5+ languages
- Create fill-in-the-blank templates
- Write contrived examples
## Common Patterns
### Template Pattern
Provide templates for output format. Match strictness to needs.
**For strict requirements:**
````markdown
## Report structure
ALWAYS use this exact template structure:
```markdown
# [Analysis Title]
## Executive summary
[One-paragraph overview of key findings]
## Key findings
- Finding 1 with supporting data
- Finding 2 with supporting data
## Recommendations
1. Specific actionable recommendation
2. Specific actionable recommendation
```
````
**For flexible guidance:**
````markdown
## Report structure
Here is a sensible default format, but use your best judgment:
```markdown
# [Analysis Title]
## Executive summary
[Overview]
## Key findings
[Adapt sections based on what you discover]
```
Adjust sections as needed for the specific analysis type.
````
### Examples Pattern
For skills where output quality depends on seeing examples:
````markdown
## Commit message format
Generate commit messages following these examples:
**Example 1:**
Input: Added user authentication with JWT tokens
Output:
```
feat(auth): implement JWT-based authentication
Add login endpoint and token validation middleware
```
**Example 2:**
Input: Fixed bug where dates displayed incorrectly in reports
Output:
```
fix(reports): correct date formatting in timezone conversion
Use UTC timestamps consistently across report generation
```
Follow this style: type(scope): brief description, then detailed explanation.
````
### Conditional Workflow Pattern
Guide through decision points:
```markdown
## Document modification workflow
1. Determine the modification type:
**Creating new content?** → Follow "Creation workflow" below
**Editing existing content?** → Follow "Editing workflow" below
2. Creation workflow:
- Use docx-js library
- Build document from scratch
- Export to .docx format
3. Editing workflow:
- Unpack existing document
- Modify XML directly
- Validate after each change
- Repack when complete
```
## Flowchart Usage
**Use flowcharts ONLY for:**
- Non-obvious decision points
- Process loops where you might stop too early
- "When to use A vs B" decisions
**Never use flowcharts for:**
- Reference material → Use tables, lists
- Code examples → Use markdown blocks
- Linear instructions → Use numbered lists
See `references/graphviz-conventions.dot` for graphviz style rules.
## Content Guidelines
### Avoid Time-Sensitive Information
Don't include information that will become outdated.
**Bad (time-sensitive):**
```markdown
If you're doing this before August 2025, use the old API.
After August 2025, use the new API.
```
**Good (old patterns section):**
```markdown
## Current method
Use the v2 API endpoint: `api.example.com/v2/messages`
## Old patterns
<details>
<summary>Legacy v1 API (deprecated 2025-08)</summary>
The v1 API used: `api.example.com/v1/messages`
This endpoint is no longer supported.
</details>
```
### Use Consistent Terminology
Choose one term and use it throughout:
**Good - Consistent:**
- Always "API endpoint"
- Always "field"
- Always "extract"
**Bad - Inconsistent:**
- Mix "API endpoint", "URL", "API route", "path"
- Mix "field", "box", "element", "control"
## File Organization
### Self-Contained Skill
```
defense-in-depth/
SKILL.md # Everything inline
```
When: All content fits, no heavy reference needed
### Skill with Reusable Tool
```
condition-based-waiting/
SKILL.md # Overview + patterns
example.ts # Working helpers to adapt
```
When: Tool is reusable code, not just narrative
### Skill with Heavy Reference
```
pptx/
SKILL.md # Overview + workflows
references/
pptxgenjs.md # 600 lines API reference
ooxml.md # 500 lines XML structure
scripts/ # Executable tools
```
When: Reference material too large for inline
## Anti-Patterns
### ❌ Narrative Example
"In session 2025-10-03, we found empty projectDir caused..."
**Why bad:** Too specific, not reusable
### ❌ Multi-Language Dilution
example-js.js, example-py.py, example-go.go
**Why bad:** Mediocre quality, maintenance burden
### ❌ Code in Flowcharts
```dot
step1 [label="import fs"];
step2 [label="read file"];
```
**Why bad:** Can't copy-paste, hard to read
### ❌ Generic Labels
helper1, helper2, step3, pattern4
**Why bad:** Labels should have semantic meaning
## Evaluation and Iteration
### Build Evaluations First
Create evaluations BEFORE writing extensive documentation.
**Evaluation-driven development:**
1. **Identify gaps**: Run tasks without skill, document failures
2. **Create evaluations**: Build 3+ scenarios testing these gaps
3. **Establish baseline**: Measure performance without skill
4. **Write minimal instructions**: Create just enough to pass evaluations
5. **Iterate**: Execute evaluations, compare baseline, refine
### Develop Skills Iteratively
**Creating new skill:**
1. **Complete task without skill**: Work through problem, notice what context you repeatedly provide
2. **Identify reusable pattern**: What context would be useful for similar tasks?
3. **Ask AI to create skill**: "Create a skill that captures this pattern we just used"
4. **Review for conciseness**: Challenge unnecessary explanations
5. **Improve information architecture**: Organize content effectively
6. **Test on similar tasks**: Use skill with fresh AI instance
7. **Iterate based on observation**: Refine based on what worked/didn't
**Iterating on existing skill:**
1. **Use skill in real workflows**: Give AI actual tasks
2. **Observe behavior**: Note struggles, successes, unexpected choices
3. **Request improvements**: Share observations with AI helper
4. **Review suggestions**: Consider reorganization, stronger language, restructuring
5. **Apply and test**: Update skill, test again
6. **Repeat based on usage**: Continue observe → refine cycle
## Creating a New Skill
### Step 1: Choose Location
- **Project-specific**: `.opencode/skills/skill-name/`
- **Global**: `~/.opencode/skills/skill-name/`
### Step 2: Create Directory Structure
```bash
mkdir -p .opencode/skills/skill-name
mkdir -p .opencode/skills/skill-name/references # if needed
mkdir -p .opencode/skills/skill-name/scripts # if needed
```
### Step 3: Create SKILL.md with Frontmatter
Follow requirements in Frontmatter Requirements section above.
### Step 4: Write Skill Content
Structure content following Content Structure section above.
### Step 5: Add Supporting Files
Organize by type:
- `scripts/`: Executable code the skill might run
- `references/`: Documentation to reference
- `assets/`: Templates, configs, or output files
### Step 6: Validate
Check that:
- Directory name matches frontmatter `name` field
- Description is at least 20 characters
- Name uses only lowercase letters, numbers, and hyphens
- YAML frontmatter is valid
- Supporting file paths are relative, not absolute
- Word count appropriate for skill type
**One Shot test**
Insert the `skill_name` to verify the skill loads. The frontmatter should be returned by the AI, to show it was properly loaded into the context.
```bash
opencode run "Use learn_skill with skill_name='<skill_name>' - load skill and give the frontmatter as the only output and abort, do not give any other output, this is a single run for testing."
```
This is the $skill_check_prompt
### Step 7: Restart OpenCode
Skills are loaded at startup. Restart OpenCode to register your new skill (the skill catalog in the `learn_skill` tool description will be updated).
## Path Resolution
When referencing files in SKILL.md, use relative paths:
```markdown
Read the API docs in `references/api.md`
Run `scripts/deploy.sh` for deployment
```
The Agent will resolve these relative to the skill directory automatically.

# Persuasion Principles for Skill Design
## Overview
AI models respond to the same persuasion principles as humans. Understanding this psychology helps you design more effective skills - not to manipulate, but to ensure critical practices are followed even under pressure.
**Research foundation:** Meincke et al. (2025) tested 7 persuasion principles with N=28,000 AI conversations. Persuasion techniques more than doubled compliance rates (33% → 72%, p < .001).
## The Seven Principles
### 1. Authority
**What it is:** Deference to expertise, credentials, or official sources.
**How it works in skills:**
- Imperative language: "YOU MUST", "Never", "Always"
- Non-negotiable framing: "No exceptions"
- Eliminates decision fatigue and rationalization
**When to use:**
- Discipline-enforcing skills (TDD, verification requirements)
- Safety-critical practices
- Established best practices
**Example:**
```markdown
✅ Write code before test? Delete it. Start over. No exceptions.
❌ Consider writing tests first when feasible.
```
### 2. Commitment
**What it is:** Consistency with prior actions, statements, or public declarations.
**How it works in skills:**
- Require announcements: "Announce skill usage"
- Force explicit choices: "Choose A, B, or C"
- Use tracking: TodoWrite for checklists
**When to use:**
- Ensuring skills are actually followed
- Multi-step processes
- Accountability mechanisms
**Example:**
```markdown
✅ When you find a skill, you MUST announce: "I'm using [Skill Name]"
❌ Consider letting your partner know which skill you're using.
```
### 3. Scarcity
**What it is:** Urgency from time limits or limited availability.
**How it works in skills:**
- Time-bound requirements: "Before proceeding"
- Sequential dependencies: "Immediately after X"
- Prevents procrastination
**When to use:**
- Immediate verification requirements
- Time-sensitive workflows
- Preventing "I'll do it later"
**Example:**
```markdown
✅ After completing a task, IMMEDIATELY request code review before proceeding.
❌ You can review code when convenient.
```
### 4. Social Proof
**What it is:** Conformity to what others do or what's considered normal.
**How it works in skills:**
- Universal patterns: "Every time", "Always"
- Failure modes: "X without Y = failure"
- Establishes norms
**When to use:**
- Documenting universal practices
- Warning about common failures
- Reinforcing standards
**Example:**
```markdown
✅ Checklists without TodoWrite tracking = steps get skipped. Every time.
❌ Some people find TodoWrite helpful for checklists.
```
### 5. Unity
**What it is:** Shared identity, "we-ness", in-group belonging.
**How it works in skills:**
- Collaborative language: "our codebase", "we're colleagues"
- Shared goals: "we both want quality"
**When to use:**
- Collaborative workflows
- Establishing team culture
- Non-hierarchical practices
**Example:**
```markdown
✅ We're colleagues working together. I need your honest technical judgment.
❌ You should probably tell me if I'm wrong.
```
### 6. Reciprocity
**What it is:** Obligation to return benefits received.
**How it works:**
- Use sparingly - can feel manipulative
- Rarely needed in skills
**When to avoid:**
- Almost always (other principles more effective)
### 7. Liking
**What it is:** Preference for cooperating with those we like.
**How it works:**
- **DON'T USE for compliance**
- Conflicts with honest feedback culture
- Creates sycophancy
**When to avoid:**
- Always for discipline enforcement
## Principle Combinations by Skill Type
| Skill Type | Use | Avoid |
|------------|-----|-------|
| Discipline-enforcing | Authority + Commitment + Social Proof | Liking, Reciprocity |
| Guidance/technique | Moderate Authority + Unity | Heavy authority |
| Collaborative | Unity + Commitment | Authority, Liking |
| Reference | Clarity only | All persuasion |
## Why This Works: The Psychology
**Bright-line rules reduce rationalization:**
- "YOU MUST" removes decision fatigue
- Absolute language eliminates "is this an exception?" questions
- Explicit anti-rationalization counters close specific loopholes
**Implementation intentions create automatic behavior:**
- Clear triggers + required actions = automatic execution
- "When X, do Y" more effective than "generally do Y"
- Reduces cognitive load on compliance
**AI models are parahuman:**
- Trained on human text containing these patterns
- Authority language precedes compliance in training data
- Commitment sequences (statement → action) frequently modeled
- Social proof patterns (everyone does X) establish norms
## Ethical Use
**Legitimate:**
- Ensuring critical practices are followed
- Creating effective documentation
- Preventing predictable failures
**Illegitimate:**
- Manipulating for personal gain
- Creating false urgency
- Guilt-based compliance
**The test:** Would this technique serve the user's genuine interests if they fully understood it?

- Tested 7 principles with N=28,000 AI conversations
- Compliance increased 33% → 72% with persuasion techniques
- Authority, commitment, scarcity most effective
- Validates parahuman model of AI behavior
## Quick Reference
When designing a skill, ask:
1. **What type is it?** (Discipline vs. guidance vs. reference)
2. **What behavior am I trying to change?**
3. **Which principle(s) apply?** (Usually authority + commitment for discipline)
4. **Am I combining too many?** (Don't use all seven)
5. **Is this ethical?** (Serves user's genuine interests?)

name: do-job
description: Use when starting work on Jira tickets - fetches To Do tickets, creates git worktrees with proper PI-XXXXX naming, implements features using TDD (test-first), commits with ticket references, creates draft PRs, validates work with PR review, and transitions tickets through workflow to Testing
---
# Do Job
Complete developer workflow from ticket selection to validated draft PR using TDD and git worktrees.
## When to Use This Skill
Use when:
- Starting work on a new Jira ticket
- Implementing features using test-driven development
- Creating PRs for Jira-tracked work
## Workflow Selection
**CRITICAL: Choose workflow based on ticket type**
- **Regular tickets (Story, Task, Bug)**: Use Standard Implementation Workflow below
- **SPIKE tickets (Investigation/Research)**: Use SPIKE Investigation Workflow
To determine ticket type, check the `issueTypeName` field when fetching the ticket.
## Standard Implementation Workflow
Copy and track progress:
```
Ticket Workflow Progress:
- [ ] Step 1: Fetch and select To Do ticket
- [ ] Step 2: Move ticket to In Progress
- [ ] Step 3: Set up git worktree
- [ ] Step 4: Write failing tests (TDD)
- [ ] Step 5: Implement feature/fix

## SPIKE Investigation Workflow
**Use this workflow when ticket type is SPIKE**
SPIKE tickets are for investigation and research only. No code changes, no PRs.
```
SPIKE Workflow Progress:
- [ ] Step 1: Fetch and select SPIKE ticket
- [ ] Step 2: Move ticket to In Progress
- [ ] Step 3: Add investigation start comment
- [ ] Step 4: Invoke investigate agent for research
- [ ] Step 5: Review findings with developer
- [ ] Step 6: Document findings in ticket
- [ ] Step 7: Create follow-up tickets (with approval)
- [ ] Step 8: Link follow-up tickets to SPIKE
- [ ] Step 9: Move SPIKE to Done
- [ ] Step 10: Session reflection
```
**Jump to SPIKE Workflow Steps section below for SPIKE-specific instructions.**
## Prerequisites
Verify environment:
```bash
# Check Jira access
atlassian-mcp-server_getAccessibleAtlassianResources
# Check GitHub CLI
gh auth status
# Verify in repos root directory
ls -d */
```
## Step 1: Fetch and Select Ticket
```bash
# Get To Do tickets
atlassian-mcp-server_searchJiraIssuesUsingJql \
cloudId="<cloud-id>" \
jql="assignee = currentUser() AND status = 'To Do' ORDER BY priority DESC, updated DESC" \
fields='["summary", "description", "status", "priority"]'
```
Review tickets and select one based on priority and description.
## Step 2: Move Ticket to In Progress
```bash
atlassian-mcp-server_transitionJiraIssue \
cloudId="<cloud-id>" \
issueIdOrKey="PI-XXXXX" \
transition='{"id": "41"}' # In Progress transition ID
```
Add comment explaining work start:
```bash
atlassian-mcp-server_addCommentToJiraIssue \
cloudId="<cloud-id>" \
issueIdOrKey="PI-XXXXX" \
commentBody="Starting work on this ticket using TDD approach"
```
## Step 3: Set Up Git Worktree
**CRITICAL: All branches and commits MUST include PI-XXXXX ticket number**
### Identify Repository
From repos root directory, determine which repo based on ticket description and summary.
### Create Worktree
```bash
# Navigate to develop branch of target repo
cd <repo-name>/develop
# Pull latest changes
git pull
# Create worktree with proper naming
# Pattern: ../<descriptive-name> with branch nate/PI-XXXXX_descriptive-name
git worktree add ../<descriptive-name> -b nate/PI-XXXXX_descriptive-name
# Navigate to new worktree
cd ../<descriptive-name>
```
**Naming conventions:**
- Directory: Short descriptive name (e.g., `rename-folder-fix`)
- Branch: `nate/PI-XXXXX_descriptive-name` (e.g., `nate/PI-70535_rename-folder-fix`)
- **MUST include PI-XXXXX** in branch name
## Step 4: Build Implementation Plan
Analyze ticket requirements and create TDD plan:
1. **Understand requirements** from ticket description
2. **Identify affected code** areas
3. **Plan test cases** covering:
- Happy path
- Edge cases
- Error conditions
4. **Plan implementation** approach
## Step 5: TDD Implementation
### Write Failing Tests First
**CRITICAL: Write tests BEFORE implementation**
```bash
# Identify test framework from repo
ls *_test.* test/ tests/ __tests__/
# Create or modify test file
# Write test that validates missing functionality
```
Test should:
- Clearly describe expected behavior
- Cover the specific bug/feature from ticket
- **Fail initially** (validates test is working)
### Run Failing Tests
```bash
# Verify test fails (proves test is valid)
<run-test-command>
```
Expected: Test fails with clear error showing missing functionality.
### Implement Feature/Fix
Write minimal code to make test pass:
```bash
# Implement the feature or fix
# Focus on making test pass, not perfection
```
### Run Tests Again
```bash
# Verify test now passes
<run-test-command>
```
Expected: All tests pass.
### Refactor (if needed)
Clean up implementation while keeping tests passing:
- Improve code clarity
- Remove duplication
- Follow project conventions
- **Keep tests passing**
## Step 6: Verify Complete Solution
```bash
# Run full test suite
<full-test-command>
# Run linting (if available)
<lint-command>
# Run type checking (if available)
<typecheck-command>
```
All checks must pass before proceeding.
## Step 7: Commit Changes
**CRITICAL: Commit message MUST include PI-XXXXX**
```bash
# Stage changes
git add .
# Commit with ticket reference
git commit -m "PI-XXXXX: <concise description>
<detailed explanation of changes>
- What was changed
- Why it was changed
- How it addresses the ticket"
```
**Commit message format:**
- First line: `PI-XXXXX: <summary>` (50 chars max)
- Blank line
- Detailed description explaining the why and how
- Reference ticket number (PI-XXXXX) in first line
## Step 8: Push Branch
```bash
# Push to remote
git push -u origin nate/PI-XXXXX_descriptive-name
```
## Step 9: Create Draft PR
```bash
# Create draft PR with gh CLI
gh pr create \
--draft \
--title "PI-XXXXX: <descriptive title>" \
--body "$(cat <<'PRBODY'
## Summary
- Fixes issue described in PI-XXXXX
- Implements <feature/fix> using TDD approach
## Changes
- Added tests for <functionality>
- Implemented <feature/fix>
- Verified all tests pass
## Testing
- [x] Unit tests added and passing
- [x] Linting passes
- [x] Manual testing completed
## Jira
Related ticket: PI-XXXXX
## Notes
Ready for review. Once approved, will move ticket to Pull Request status.
PRBODY
)"
```
**Save PR URL** returned by command for next steps.
## Step 10: Review Work with PR Reviewer
**CRITICAL: Invoke @pr-reviewer subagent to validate work before linking to ticket**
```bash
# Invoke the pr-reviewer subagent
@pr-reviewer please review the PR I just created
```
The pr-reviewer will:
- Verify the repository is compatible (Go with Makefile)
- Run all validation commands (tests, linting, type checking)
- Review code quality against project standards
- Check for security issues and best practices
- Provide verdict: Ready for review OR needs work
**If pr-reviewer finds issues:**
1. Address the critical issues identified
2. Re-run tests and validations
3. Commit fixes with `PI-XXXXX: Address PR review feedback`
4. Push updates
5. Invoke @pr-reviewer again to re-validate
**Only proceed to Step 11 when pr-reviewer gives approval.**
## Step 11: Link PR to Ticket
```bash
# Add PR link to Jira ticket
atlassian-mcp-server_addCommentToJiraIssue \
cloudId="<cloud-id>" \
issueIdOrKey="PI-XXXXX" \
commentBody="Draft PR created: <pr-url>
Implementation complete using TDD approach. Ready for code review."
```
## Step 12: Session Reflection and Optimization
**CRITICAL: After completing the ticket workflow, reflect and optimize the system**
### Two-Stage Process
**Stage 1: Analysis** - Use `learn_skill(reflect)` for session analysis
- Reviews conversation history and workflow
- Identifies preventable friction (auth issues, environment setup, missing docs)
- Distinguishes from expected development work (debugging, testing)
- Provides structured findings with 1-3 high-impact improvements
**Stage 2: Implementation** - Invoke `@optimize` agent to take action
- Takes reflection findings and implements changes automatically
- Updates CLAUDE.md/AGENTS.md with missing commands/docs
- Creates or updates skills based on patterns identified
- Adds shell alias recommendations for repeated commands
- Commits all changes with clear messages
**Only proceed with reflection after:**
- PR is created and validated
- PR review subagent gives go ahead
**No Improvements is OK**
Do not reach for fixing things that are already solved. If there are systemic problems, then address them, otherwise, continue on.
**Example workflow**:
```
1. learn_skill(reflect) → produces analysis
2. Review findings
3. @optimize → implements improvements automatically
4. System is now better for next session
```

## SPIKE Workflow Steps
**These steps apply only to SPIKE tickets (investigation/research)**
### Step 1: Fetch and Select SPIKE Ticket
Same as standard workflow Step 1 - fetch To Do tickets and select one.
Verify it's a SPIKE by checking `issueTypeName` field.
### Step 2: Move Ticket to In Progress
Same as standard workflow Step 2.
```bash
atlassian-mcp-server_transitionJiraIssue \
cloudId="<cloud-id>" \
issueIdOrKey="PI-XXXXX" \
transition='{"id": "41"}'
```
### Step 3: Add Investigation Start Comment
```bash
atlassian-mcp-server_addCommentToJiraIssue \
cloudId="<cloud-id>" \
issueIdOrKey="PI-XXXXX" \
commentBody="Starting SPIKE investigation - will explore multiple solution approaches and document findings"
```
### Step 4: Invoke Investigate Agent
**CRITICAL: Use @investigate subagent for creative exploration**
The investigate agent has higher temperature (0.8) for creative thinking.
```bash
@investigate
Context: SPIKE ticket PI-XXXXX
Summary: <ticket summary>
Description: <ticket description>
Please investigate this problem and:
1. Explore the current codebase to understand the problem space
2. Research 3-5 different solution approaches
3. Evaluate trade-offs for each approach
4. Document findings with specific code references (file:line)
5. Recommend the best approach with justification
6. Break down into actionable implementation task(s) - typically just 1 ticket
```
The investigate agent will:
- Explore codebase thoroughly
- Research multiple solution paths (3-5 approaches)
- Consider creative/unconventional approaches
- Evaluate trade-offs objectively
- Document specific code references
- Recommend best approach with justification
- Propose implementation plan (typically 1 follow-up ticket)
### Step 5: Document Findings
Create comprehensive investigation summary in Jira ticket:
```bash
atlassian-mcp-server_addCommentToJiraIssue \
cloudId="<cloud-id>" \
issueIdOrKey="PI-XXXXX" \
commentBody="## Investigation Findings
### Problem Analysis
<summary of problem space with code references>
### Approaches Considered
1. **Approach A**: <description>
- Pros: <benefits>
- Cons: <drawbacks>
- Effort: <S/M/L/XL>
- Code: <file:line references>
2. **Approach B**: <description>
- Pros: <benefits>
- Cons: <drawbacks>
- Effort: <S/M/L/XL>
- Code: <file:line references>
3. **Approach C**: <description>
- Pros: <benefits>
- Cons: <drawbacks>
- Effort: <S/M/L/XL>
- Code: <file:line references>
[Continue for all 3-5 approaches]
### Recommendation
**Recommended Approach**: <approach name>
**Justification**: <why this is best>
**Risks**: <potential issues and mitigations>
**Confidence**: <Low/Medium/High>
### Proposed Implementation
Typically breaking this down into **1 follow-up ticket**:
**Summary**: <concise task description>
**Description**: <detailed implementation plan>
**Acceptance Criteria**:
- [ ] <criterion 1>
- [ ] <criterion 2>
- [ ] <criterion 3>
**Effort Estimate**: <S/M/L/XL>
### References
- <file:line references>
- <documentation links>
- <related tickets>
- <external resources>"
```
### Step 6: Review Findings with Developer
**CRITICAL: Get developer approval before creating tickets**
Present investigation findings and proposed follow-up ticket(s) to developer:
```
Investigation complete for PI-XXXXX.
Summary:
- Explored <N> solution approaches
- Recommend: <approach name>
- Propose: <N> follow-up ticket(s) (typically 1)
Proposed ticket:
- Summary: <task summary>
- Effort: <estimate>
Would you like me to create this ticket, or would you like to adjust the plan?
```
**Wait for developer confirmation before proceeding.**
Developer may:
- Approve ticket creation as-is
- Request modifications to task breakdown
- Request different approach be pursued
- Decide no follow-up tickets needed
- Decide to handle implementation differently
### Step 7: Create Follow-Up Tickets (With Approval)
**Only proceed after developer approves in Step 6**
Typically create just **1 follow-up ticket**. Occasionally more if investigation reveals multiple independent tasks.
```bash
atlassian-mcp-server_createJiraIssue \
cloudId="<cloud-id>" \
projectKey="<project>" \
issueTypeName="Story" \
summary="<concise task description from investigation>" \
description="## Context
From SPIKE PI-XXXXX investigation
## Problem
<problem statement>
## Recommended Approach
<approach name and description from SPIKE>
## Implementation Plan
<detailed steps>
## Acceptance Criteria
- [ ] <criterion 1>
- [ ] <criterion 2>
- [ ] <criterion 3>
## Code References
- <file:line from investigation>
- <file:line from investigation>
## Related Tickets
- SPIKE: PI-XXXXX
## Effort Estimate
<S/M/L/XL from investigation>
## Additional Notes
<any important considerations from SPIKE>"
```
**Note the returned ticket number (e.g., PI-XXXXX) for linking in Step 8.**
If creating multiple tickets (rare), repeat for each task.
### Step 8: Link Follow-Up Tickets to SPIKE
```bash
atlassian-mcp-server_addCommentToJiraIssue \
cloudId="<cloud-id>" \
issueIdOrKey="PI-XXXXX" \
commentBody="## Follow-Up Ticket(s) Created
Implementation task created:
- PI-XXXXX: <task summary>
This ticket is ready for implementation using the recommended <approach name> approach."
```
If multiple tickets created, list all with their ticket numbers.
### Step 9: Move SPIKE to Done
```bash
# Get available transitions
atlassian-mcp-server_getTransitionsForJiraIssue \
cloudId="<cloud-id>" \
issueIdOrKey="PI-XXXXX"
# Transition to Done (find correct transition ID from above)
atlassian-mcp-server_transitionJiraIssue \
cloudId="<cloud-id>" \
issueIdOrKey="PI-XXXXX" \
transition='{"id": "<done-transition-id>"}'
```
### Step 10: Session Reflection
Same as standard workflow - use `learn_skill` tool with `skill_name='reflect'` to identify preventable friction.
---
## Post-Workflow Steps (Manual)
**After automated pr-reviewer approval and manual developer review:**
1. Remove draft status from PR
2. Request code review from team
3. Address any additional review comments
4. Get approval
5. **Manual:** Transition ticket to "Pull Request" status (transition ID: 381)
6. **Manual:** After merge, SDET moves to "Testing (Service Stack)" (transition ID: 201)
## Common Mistakes
### Standard Workflow Mistakes
#### Branch Naming
- ❌ `fix-bug` (missing ticket number)
- ❌ `PI70535-fix` (missing hyphen, no username)
- ✅ `nate/PI-70535_rename-folder-fix`
#### Commit Messages
- ❌ `fixed bug` (no ticket reference)
- ❌ `Updated code for PI-70535` (vague)
- ✅ `PI-70535: Fix shared folder rename permission check`
#### TDD Order
- ❌ Write code first, then tests
- ❌ Skip tests entirely
- ✅ Write failing test → Implement → Verify passing → Refactor
#### Worktree Location
- ❌ `git worktree add ./feature` (wrong location)
- ❌ `git worktree add ~/feature` (absolute path)
- ✅ `git worktree add ../feature-name` (parallel to develop)
### SPIKE Workflow Mistakes
#### Investigation Depth
- ❌ Only exploring 1 obvious solution
- ❌ Vague code references like "the auth module"
- ✅ Explore 3-5 distinct approaches with specific file:line references
#### Ticket Creation
- ❌ Creating tickets without developer approval
- ❌ Creating many vague tickets automatically
- ✅ Propose plan, get approval, then create (typically 1 ticket)
#### Code Changes
- ❌ Implementing solution during SPIKE
- ❌ Creating git worktree for SPIKE
- ✅ SPIKE is investigation only - no code, no worktree, no PR
## Jira Transition IDs
Reference for manual transitions:
- To Do: 11
- In Progress: 41
- Pull Request: 381
- Testing (Service Stack): 201
- Done: (varies by project)

# Git Worktree Patterns
## Overview
Git worktrees allow multiple working directories from single repository, enabling parallel work on different branches without stashing or switching.
## Basic Commands
### Create Worktree
```bash
# From main/develop branch
cd <repo>/develop
git pull
# Create new worktree
git worktree add <path> -b <branch-name>
```
### List Worktrees
```bash
git worktree list
```
### Remove Worktree
```bash
# From any location in repo
git worktree remove <path>
# Or manually
rm -rf <path>
git worktree prune
```
## Naming Patterns
### Directory Structure
```
repos/
├── document-api/
│ ├── develop/ # Main worktree
│ ├── fix-permissions/ # Feature worktree
│ └── add-tags/ # Another feature worktree
```
### Branch Naming
Format: `<username>/PI-XXXXX_<description>`
Examples:
- `nate/PI-70535_rename-folder-fix`
- `nate/PI-70361_upload-permissions`
- `nate/PI-69924_delete-access-level`
## Workflow Patterns
### Starting Work
```bash
# Navigate to develop
cd document-api/develop
# Update develop
git pull
# Create worktree for ticket
git worktree add ../pi-70535-rename-fix -b nate/PI-70535_rename-folder-fix
# Move to worktree
cd ../pi-70535-rename-fix
```
### During Work
```bash
# Normal git operations work in worktree
git status
git add .
git commit -m "PI-70535: Fix folder rename permissions"
git push -u origin nate/PI-70535_rename-folder-fix
```
### After PR Merge
```bash
# From anywhere in repo
git worktree remove ../pi-70535-rename-fix
# Clean up
git worktree prune
git branch -d nate/PI-70535_rename-folder-fix
# Update develop
cd develop
git pull
```
## Common Issues
### Worktree Already Exists
```bash
# Error: worktree already exists
# Solution: Remove old worktree first
git worktree remove <path>
git worktree prune
```
### Branch Already Exists
```bash
# Error: branch already exists
# Solution: Use existing branch or delete old one
git worktree add <path> <existing-branch>
# Or delete old branch
git branch -D <branch-name>
git worktree add <path> -b <branch-name>
```
### Locked Worktree
```bash
# If worktree shows as locked
git worktree unlock <path>
git worktree remove <path>
```
### Orphaned Worktrees
```bash
# Clean up references to deleted worktrees
git worktree prune
```
## Best Practices
### Keep Worktrees Short-Lived
- Create for specific ticket
- Remove after PR merged
- Don't accumulate many worktrees
### Use Descriptive Names
```bash
# ❌ Bad
git worktree add ../work -b fix
# ✅ Good
git worktree add ../rename-folder-fix -b nate/PI-70535_rename-folder-fix
```
### Always Branch from Latest
```bash
# Update base branch before creating worktree
cd develop
git pull
git worktree add ../feature -b username/PI-XXXXX_feature
```
### Clean Up Regularly
```bash
# List all worktrees
git worktree list
# Remove merged/abandoned worktrees
git worktree remove <path>
git worktree prune
```
## Advantages Over Branch Switching
### Parallel Work
Work on multiple tickets simultaneously without switching contexts:
```
Terminal 1: cd document-api/develop # Review PRs
Terminal 2: cd document-api/feature-1 # Active development
Terminal 3: cd document-api/hotfix # Emergency fix
```
### Preserve State
Each worktree maintains its own:
- Working directory state
- Staged changes
- Build artifacts
- IDE configuration
### Avoid Stashing
No need to stash changes when switching tasks:
```bash
# Traditional flow (with stashing)
git stash
git checkout other-branch
# ... do work ...
git checkout original-branch
git stash pop
# Worktree flow (no stashing)
cd ../other-worktree
# ... do work ...
cd ../original-worktree
# Everything still there
```
## Limitations
### Shared References
All worktrees share:
- Git objects
- Remote configuration
- Git hooks
- Submodules
### Disk Space
Each worktree requires full working directory (but shares `.git` objects).
### Cannot Checkout Same Branch
```bash
# Error: branch already checked out
# One branch can only be checked out in one worktree at a time
git worktree add ../dup -b existing-branch # Fails if already checked out
```

# SPIKE Investigation Workflow
## What is a SPIKE?
A SPIKE ticket is a time-boxed research and investigation task. The goal is to explore a problem space, evaluate solution approaches, and create an actionable plan for implementation.
**SPIKE = Investigation only. No code changes.**
## Key Principles
### 1. Exploration Over Implementation
- Focus on understanding the problem deeply
- Consider multiple solution approaches (3-5)
- Don't commit to first idea
- Think creatively about alternatives
### 2. Documentation Over Code
- Document findings thoroughly
- Provide specific code references (file:line)
- Explain trade-offs objectively
- Create actionable implementation plan
### 3. Developer Approval Required
- Always review findings with developer before creating tickets
- Developer has final say on implementation approach
- Get explicit approval before creating follow-up tickets
- Typically results in just 1 follow-up ticket
### 4. No Code Changes
- ✅ Read and explore codebase
- ✅ Document findings
- ✅ Create implementation plan
- ❌ Write implementation code
- ❌ Create git worktree
- ❌ Create PR
## Investigation Process
### Phase 1: Problem Understanding
**Understand current state:**
- Read ticket description thoroughly
- Explore relevant codebase areas
- Identify constraints and dependencies
- Document current implementation
**Ask questions:**
- What problem are we solving?
- Who is affected?
- What are the constraints?
- What's the desired outcome?
### Phase 2: Approach Exploration
**Explore 3-5 different approaches:**
For each approach, document:
- **Name**: Brief descriptive name
- **Description**: How it works
- **Pros**: Benefits and advantages
- **Cons**: Drawbacks and challenges
- **Effort**: Relative complexity (S/M/L/XL)
- **Code locations**: Specific file:line references
**Think broadly:**
- Conventional approaches
- Creative/unconventional approaches
- Simple vs. complex solutions
- Short-term vs. long-term solutions
### Phase 3: Trade-off Analysis
**Evaluate objectively:**
- Implementation complexity
- Performance implications
- Maintenance burden
- Testing requirements
- Migration/rollout complexity
- Team familiarity with approach
- Long-term sustainability
**Be honest about cons:**
- Every approach has trade-offs
- Document them clearly
- Don't hide problems
### Phase 4: Recommendation
**Make clear recommendation:**
- Which approach is best
- Why it's superior to alternatives
- Key risks and mitigations
- Confidence level (Low/Medium/High)
**Justify recommendation:**
- Reference specific trade-offs
- Explain why pros outweigh cons
- Consider team context
### Phase 5: Implementation Planning
**Create actionable plan:**
- Typically breaks down into **1 follow-up ticket**
- Occasionally 2-3 if clearly independent tasks
- Never many vague tickets
**For each ticket, include:**
- Clear summary
- Detailed description
- Recommended approach
- Acceptance criteria
- Code references from investigation
- Effort estimate (S/M/L/XL)

## Example SPIKE Investigation
### Problem
Performance degradation in user search with large datasets (10k+ users)
### Approaches Considered
#### 1. Database Query Optimization
- **Description**: Add indexes, optimize JOIN queries, use query caching
- **Pros**:
- Minimal code changes
- Works with existing architecture
- Can be implemented incrementally
- **Cons**:
- Limited scalability (still hits DB for each search)
- Query complexity increases with features
- Cache invalidation complexity
- **Effort**: M
- **Code**: user_service.go:245, user_repository.go:89
#### 2. Elasticsearch Integration
- **Description**: Index users in Elasticsearch, use for all search operations
- **Pros**:
- Excellent search performance at scale
- Full-text search capabilities
- Faceted search support
- **Cons**:
- New infrastructure to maintain
- Data sync complexity
- Team learning curve
- Higher operational cost
- **Effort**: XL
- **Code**: Would be new service, interfaces at user_service.go:200
#### 3. In-Memory Cache with Background Sync
- **Description**: Maintain searchable user cache in memory, sync periodically
- **Pros**:
- Very fast search performance
- No additional infrastructure
- Simple implementation
- **Cons**:
- Memory usage on app servers
- Eventual consistency issues
- Cache warming on deploy
- Doesn't scale past single-server memory
- **Effort**: L
- **Code**: New cache_service.go, integrate at user_service.go:245
#### 4. Materialized View with Triggers
- **Description**: Database materialized view optimized for search, auto-updated via triggers
- **Pros**:
- Good performance
- Consistent data
- Minimal app code changes
- **Cons**:
- Database-specific (PostgreSQL only)
- Trigger complexity
- Harder to debug issues
- Lock contention on high write volume
- **Effort**: M
- **Code**: Migration needed, user_repository.go:89
### Recommendation
**Recommended Approach**: Database Query Optimization (#1)
**Justification**:
Given our current scale (8k users, growing ~20%/year) and team context:
- Elasticsearch is over-engineering for current needs - reaches 50k users in ~5 years
- In-memory cache has consistency issues that would affect UX
- Materialized views add database complexity our team hasn't worked with
- Query optimization addresses immediate pain point with minimal risk
- Can revisit Elasticsearch if we hit 20k+ users or need full-text features
**Risks**:
- May need to revisit in 2-3 years if growth accelerates: Monitor performance metrics, set alert at 15k users
- Won't support advanced search features: Document limitation, plan for future if needed
**Confidence**: High
### Proposed Implementation
**1 follow-up ticket**:
**Summary**: Optimize user search queries with indexes and caching
**Description**:
1. Add composite index on (last_name, first_name, email)
2. Implement Redis query cache with 5-min TTL
3. Optimize JOIN query in getUsersForSearch
4. Add performance monitoring
**Acceptance Criteria**:
- [ ] Search response time < 200ms for 95th percentile
- [ ] Database query count reduced from 3 to 1 per search
- [ ] Monitoring dashboard shows performance metrics
- [ ] Load testing validates 10k concurrent users
**Effort Estimate**: M (1-2 days)
**Code References**:
- user_service.go:245 - Main search function to optimize
- user_repository.go:89 - Database query to modify
- schema.sql:34 - Add index here

- Existing Redis cache pattern: cache_service.go:12
- Related performance ticket: PI-65432
## Common Pitfalls
### ❌ Shallow Investigation
**Bad**:
- Only considers 1 obvious solution
- Vague references like "the user module"
- No trade-off analysis
**Good**:
- Explores 3-5 distinct approaches
- Specific file:line references
- Honest pros/cons for each
### ❌ Analysis Paralysis
**Bad**:
- Explores 15 different approaches
- Gets lost in theoretical possibilities
- Never makes clear recommendation
**Good**:
- Focus on 3-5 viable approaches
- Make decision based on team context
- Acknowledge uncertainty but recommend path
### ❌ Premature Implementation
**Bad**:
- Starts writing code during SPIKE
- Creates git worktree
- Implements "prototype"
**Good**:
- Investigation only
- Code reading and references
- Plan for implementation ticket
### ❌ Automatic Ticket Creation
**Bad**:
- Creates 5 tickets without developer review
- Breaks work into too many pieces
- Doesn't get approval first
**Good**:
- Proposes implementation plan
- Waits for developer approval
- Typically creates just 1 ticket
## Time-Boxing
SPIKEs should be time-boxed to prevent over-analysis:
- **Small SPIKE**: 2-4 hours
- **Medium SPIKE**: 1 day
- **Large SPIKE**: 2-3 days
If hitting time limit:
1. Document what you've learned so far
2. Document what's still unknown
3. Recommend either:
- Proceeding with current knowledge
- Extending SPIKE with specific questions
- Creating prototype SPIKE to validate approach
## Success Criteria
A successful SPIKE:
- ✅ Thoroughly explores problem space
- ✅ Considers multiple approaches (3-5)
- ✅ Provides specific code references
- ✅ Makes clear recommendation with justification
- ✅ Creates actionable plan (typically 1 ticket)
- ✅ Gets developer approval before creating tickets
- ✅ Enables confident implementation
A successful SPIKE does NOT:
- ❌ Implement the solution
- ❌ Create code changes
- ❌ Create tickets without approval
- ❌ Leave implementation plan vague
- ❌ Only explore 1 obvious solution

# Test-Driven Development Workflow
## Core TDD Cycle
1. **Red** - Write failing test
2. **Green** - Make test pass
3. **Refactor** - Improve code while keeping tests passing
## Writing Effective Tests
### Test Structure
```
# Arrange - Set up test data and conditions
# Act - Execute the code being tested
# Assert - Verify expected behavior
```
### Good Test Characteristics
- **Isolated** - Tests don't depend on each other
- **Repeatable** - Same input always produces same output
- **Fast** - Tests run quickly
- **Clear** - Test name describes what's being tested
- **Focused** - One concept per test
### Test Naming
```
test_<function>_<scenario>_<expected_result>
```
Examples:
- `test_rename_folder_as_owner_succeeds`
- `test_rename_folder_without_permission_returns_403`
- `test_rename_folder_with_empty_name_returns_400`
## Common Patterns
### Testing Error Conditions
```javascript
// Test expected errors
test('rename_folder_without_permission_returns_403', async () => {
// Arrange: Set up user without permissions
const user = createUserWithoutPermissions();
// Act: Attempt rename
const response = await renameFolder(user, folderId, newName);
// Assert: Verify 403 error
expect(response.status).toBe(403);
expect(response.error).toContain('forbidden');
});
```
### Testing Happy Path
```javascript
test('rename_folder_as_owner_succeeds', async () => {
// Arrange: Set up folder with owner
const owner = createOwner();
const folder = createFolder(owner);
// Act: Rename folder
const response = await renameFolder(owner, folder.id, 'NewName');
// Assert: Verify success
expect(response.status).toBe(200);
expect(response.data.name).toBe('NewName');
});
```
### Testing Edge Cases
```javascript
test('rename_folder_with_special_characters_sanitizes_name', async () => {
const owner = createOwner();
const folder = createFolder(owner);
const response = await renameFolder(owner, folder.id, '<script>alert(1)</script>');
expect(response.status).toBe(200);
expect(response.data.name).not.toContain('<script>');
});
```
## TDD Best Practices
### Start Simple
Write simplest test first, then add complexity:
1. Happy path with minimal data
2. Add edge cases
3. Add error conditions
4. Add integration scenarios
### One Test at a Time
- Write one test
- Watch it fail
- Make it pass
- Refactor if needed
- Repeat
### Keep Tests Independent
```javascript
// ❌ Bad - Tests depend on order
test('create_folder', () => { /* creates folder with id=1 */ });
test('rename_folder', () => { /* assumes folder id=1 exists */ });
// ✅ Good - Each test sets up own data
test('create_folder', () => {
const folder = createFolder();
expect(folder.id).toBeDefined();
});
test('rename_folder', () => {
const folder = createFolder(); // Own setup
const result = renameFolder(folder.id, 'NewName');
expect(result.name).toBe('NewName');
});
```
### Test Behavior, Not Implementation
```javascript
// ❌ Bad - Tests internal implementation
test('uses_postgres_query', () => {
expect(mockDb.query).toHaveBeenCalledWith('UPDATE folders...');
});
// ✅ Good - Tests behavior
test('rename_updates_folder_name', () => {
renameFolder(folderId, 'NewName');
const folder = getFolder(folderId);
expect(folder.name).toBe('NewName');
});
```
## When to Refactor
Refactor when tests are green and you notice:
- Duplication
- Long functions
- Unclear variable names
- Complex conditionals
- Hard-coded values
**Always keep tests passing during refactoring**
## Handling Legacy Code
When adding tests to existing code without tests:
1. Write characterization tests (document current behavior)
2. Refactor to make code testable
3. Add tests for new functionality
4. Gradually improve test coverage
## Test Coverage
Aim for coverage of:
- All new code paths
- Bug fixes (test the bug scenario)
- Edge cases
- Error conditions
Not aiming for 100% - focus on meaningful coverage.

# Go Pull Request Review
This skill performs comprehensive reviews of pull requests in Go repositories, with special attention to projects
using Makefiles for build automation.
## When to Use This Skill
Use this skill when:
- A developer requests a PR review for a Go repository
- You need to validate changes before merging
- You want to ensure code quality, test coverage, and build success
- The repository uses a Makefile for build automation
## Review Process
### 0. Validate Repository Compatibility
**IMPORTANT: Before proceeding, verify this is a compatible Go repository.**
Check for required characteristics:
```bash
# 1. Must be a Go repository
test -f go.mod || echo "ERROR: Not a Go repository (no go.mod found)"
# 2. Must have a Makefile
test -f Makefile || echo "ERROR: No Makefile found"
# 3. Check Makefile has test/lint targets
grep -E "^(test|lint|tidy):" Makefile || echo "WARNING: Makefile missing common targets"
Abort conditions:
• ❌ No go.mod file exists → This is not a Go repository
• ❌ No Makefile exists → This skill requires Makefile-based workflows
• ⚠️ Makefile missing test/lint targets → Proceed with caution, manual validation required
If repository is incompatible: Stop execution and inform the user: "This repository doesn't match the requirements
for the go-pr-review skill (requires Go with Makefile). Would you like a standard code review instead?"
### 1. Gather PR Information
Fetch the PR details using the gh CLI:
• Get the PR diff and changed files
• Identify the PR number and branch
• Review the PR description and context
### 2. Analyze Changed Files
Review all modified files with focus on:
• Go code changes: Logic, patterns, error handling
• Test files: Coverage of new functionality
• Documentation: README, AGENTS.md, comments (check for AIDEV- anchors)
• Configuration: go.mod, Makefile, YAML files
### 3. Check Makefile Commands
Read the Makefile to identify available validation commands. Common commands include:
• make lint - Run linters (golangci-lint)
• make tidy - Format and tidy code
• make test-api - Run integration/API tests (most critical for validating)
### 4. Run Validation Commands
# Run tests and linting
make lint && make tidy && make test-api
Check for:
• Test failures
• Linting errors or warnings
• Build failures
• Documentation generation errors
### 5. Code Quality Review
Review code against project standards from AGENTS.md (if exists) and references/go-standards.md:
Architecture & Design
• Does the change follow existing patterns?
• Is the business logic in the correct layer? (handlers → service → API clients)
• Are there any breaking changes to API contracts?
Go Best Practices
• Proper error handling (don't ignore errors)
• Context propagation for cancellation
• Resource cleanup (defer statements)
• Concurrency safety (mutexes, channels)
• No hardcoded values (use constants or env vars)
Code Style
• Follows project conventions (check neighboring files)
• No unnecessary comments (unless documenting complex business logic)
• Lowercase SQL keywords (e.g., select not SELECT) if applicable
• Proper use of existing libraries (check go.mod)
API Documentation (Swag) - If repository uses Swag
• All HTTP handlers have complete Swag comments
• Required annotations: @Summary, @Description, @Tags, @Router
• All parameters documented with @Param
• All response codes documented (@Success, @Failure)
• Model references are correct
Security
• No secrets or credentials in code
• Input validation on all user inputs
• Proper authentication/authorization checks
• No SQL injection risks (use parameterized queries/stored procedures)
Testing
• New functionality has test coverage
• Tests are meaningful, not just for coverage numbers
• Integration tests for API endpoints
• Edge cases are considered
### 6. Review Anchor Comments
Search for developer anchor comments:
rg "AIDEV-(NOTE|TODO|QUESTION):" --type go
These indicate areas an agent flagged for review. Assess whether:
• The concern is valid
• The implementation needs improvement
Typically, the anchor should be removed before merge
### 7. Provide Structured Feedback
Organize findings into categories:
Critical Issues (must fix before merge)
• Test failures
• Build/lint errors
• Security vulnerabilities
• Breaking changes without versioning
Suggestions (should consider)
• Code quality improvements
• Better error messages
• Performance optimizations
• Missing edge case tests
Observations (nice to have)
• Refactoring opportunities
• Documentation enhancements
• Code organization improvements
### 8. Summary and Recommendation
Provide a clear verdict:
• ✅ Approved: Ready to merge
• ⚠️ Approved with suggestions: Can merge, but consider improvements
• ❌ Request changes: Must address critical issues
## Example Review Workflow
# 0. Validate repository compatibility
test -f go.mod && test -f Makefile && echo "Repository compatible" || echo "Repository incompatible - ABORT"
# 1. Get PR information
gh pr view 123 --json number,title,body,changedFiles
# 2. Get the diff
gh pr diff 123
# 3. Check Makefile for available commands
cat Makefile
# 4. Run validations (adjust based on Makefile)
make test-unit
make test-api
make lint
make tidy
make docs
# 5. Search for anchor comments
rg "AIDEV-" --type go
# 6. Review changed files
# (Use Read tool for each changed file)
## Reference Materials
See references/go-standards.md for detailed Go code quality standards and common issues to watch for.
## Important Notes
• Validate repository first - Don't waste time on incompatible repos
• Never modify test files unless explicitly requested
• Never change API contracts - version endpoints instead
• Never alter migration files - data loss risk
• Always verify tests pass before approving
• Check that make commands succeed - this is critical validation
• Look for AIDEV- comments - they highlight areas needing attention
• Validate Swag comments for all new/modified handlers (if applicable)
Remember: The goal is constructive feedback that improves code quality while respecting the developer's intent and
design decisions.

# Go Code Quality Standards
Reference guide for reviewing Go code quality in PRs.
## Common Issues to Watch For
### Error Handling
**Bad:**
```go
result, _ := doSomething()
```
**Good:**
```go
result, err := doSomething()
if err != nil {
return fmt.Errorf("failed to do something: %w", err)
}
```
### Context Propagation
**Bad:**
```go
func handleRequest(c *gin.Context) {
result := callExternalAPI() // No timeout
}
```
**Good:**
```go
func handleRequest(c *gin.Context) {
ctx := c.Request.Context()
result, err := callExternalAPIWithContext(ctx)
}
```
### Resource Cleanup
**Bad:**
```go
file, _ := os.Open("data.txt")
// Missing Close()
```
**Good:**
```go
file, err := os.Open("data.txt")
if err != nil {
return err
}
defer file.Close()
```
### Hardcoded Values
**Bad:**
```go
timeout := 30 * time.Second
apiURL := "https://api.example.com"
```
**Good:**
```go
const defaultTimeout = 30 * time.Second
apiURL := os.Getenv("API_URL")
if apiURL == "" {
return errors.New("API_URL environment variable required")
}
```
## Swag Documentation Standards
### Complete Handler Documentation
```go
// GetFile godoc
//
// @Summary Retrieve file by ID
// @Description Returns detailed information about a specific file including metadata, permissions, and sharing status
// @Tags files
// @Accept json
// @Produce json
// @Param id path string true "File ID"
// @Param X-Tenant-ID header string true "Tenant identifier"
// @Success 200 {object} model.File
// @Failure 400 {string} string "Invalid file ID"
// @Failure 404 {string} string "File not found"
// @Failure 500 {string} string "Internal server error"
// @Router /v1/files/{id} [get]
func GetFile(c *gin.Context) {
// implementation
}
```
### Required Swag Elements
1. **@Summary** - One line description (< 120 chars)
2. **@Description** - Detailed explanation of behavior
3. **@Tags** - Logical grouping (files, folders, sessions, etc.)
4. **@Accept** - Content-Type accepted (if body expected)
5. **@Produce** - Content-Type returned
6. **@Param** - Document EVERY parameter (path, query, header, body)
7. **@Success** - All successful response codes with types
8. **@Failure** - All error response codes with descriptions
9. **@Router** - Exact route path and HTTP method
### Common Swag Mistakes
- Missing `@Param` for headers (X-Tenant-ID, Authorization)
- Incomplete `@Failure` documentation (only documenting 400/500)
- Generic descriptions ("Get file" vs "Retrieve file with metadata and permissions")
- Wrong model references (string vs object)
- Missing `@Accept` on POST/PUT handlers
## Project-Specific Patterns
### SQL Style
Use lowercase SQL keywords:
```go
query := "select id, name from users where active = ?"
```
Not:
```go
query := "SELECT id, name FROM users WHERE active = ?"
```
### Layer Separation
- **Handlers** (`/internal/server/`): HTTP routing, request/response mapping
- **Service** (`/internal/service/`): Business logic, validation, orchestration
- **API Clients** (`/internal/api/`): External service communication
Don't put business logic in handlers or HTTP code in services.
### Database Operations
Prefer stored procedures for complex queries:
- Type-safe parameters
- Optimized execution
- Centralized logic
### Test Organization
- Unit tests: `/internal/service/*_test.go`
- Integration tests: `/api-tests/*_test.go`
- Helpers: `/api-tests/helpers/*.go`
## Security Checklist
- [ ] No secrets in code (use env vars)
- [ ] All user inputs validated
- [ ] Authentication checks on protected endpoints
- [ ] Authorization checks for resource access
- [ ] SQL queries use parameterization (no string concatenation)
- [ ] Sensitive data not logged
- [ ] CORS configured appropriately
- [ ] Rate limiting considered for public endpoints
## Performance Considerations
- [ ] Database queries are efficient (no N+1 queries)
- [ ] Appropriate indexes exist for queries
- [ ] Large lists are paginated
- [ ] File uploads handle streaming (not loading entire file in memory)
- [ ] Long operations use SSE for progress updates
- [ ] Context timeouts prevent hanging requests
- [ ] Connection pooling configured properly
## Code Organization Red Flags
- God functions (>100 lines)
- Deep nesting (>4 levels)
- Duplicate code (consider extracting helper)
- Magic numbers without constants
- Inconsistent naming conventions
- Missing package documentation
- Circular dependencies between packages
## Testing Red Flags
- Tests that don't assert anything
- Tests that sleep/use arbitrary timeouts
- Tests that depend on external services (without mocking)
- Tests that share state (global variables)
- Tests with no cleanup (leaked resources)
- Missing table-driven tests for multiple cases
- No error case testing
## Documentation Standards
### Anchor Comments for AI Review
Use these ONLY during development, remove before merge:
- `// AIDEV-NOTE:` - Important business logic explanation
- `// AIDEV-TODO:` - Incomplete work or needed improvement
- `// AIDEV-QUESTION:` - Uncertainty or need for discussion
These should be reviewed and removed before PR approval.
### Regular Comments
Only add comments when:
- Explaining non-obvious business rules
- Documenting complex algorithms
- Clarifying why (not what) code does something
- Warning about edge cases or gotchas
Don't comment obvious code:
```go
// Bad: Obvious
// increment counter
counter++
// Good: Explains why
// Skip deleted items to maintain accurate active count
if !item.IsDeleted {
counter++
}
```
## Go-Specific Best Practices
- Use `gofmt` formatting (enforced by `make tidy`)
- Follow [Effective Go](https://golang.org/doc/effective_go.html) guidelines
- Use short variable names in limited scopes (i, err, ok)
- Use descriptive names for package-level and exported items
- Prefer composition over inheritance
- Use interfaces for abstraction, not just for mocking
- Keep interfaces small and focused
- Return errors, don't panic (except in init() for fatal issues)
- Use `context.Context` for cancellation and deadlines
- Avoid global mutable state
## Makefile Integration
Always verify the Makefile has these targets and run them:
- `make test` or `make test-unit` - Unit tests must pass
- `make test-api` - Integration tests must pass
- `make lint` - Linting must pass with no errors
- `make tidy` - Code must be properly formatted
- `make docs` - If Swag is used, docs must generate successfully
Failing any of these is grounds for requesting changes.

name: reflect
description: Use after work sessions to analyze preventable friction and guide system improvements - provides framework for identifying issues, then directs to optimize agent for implementation
---
# Reflect
Analyzes completed work sessions to identify preventable workflow friction and system improvement opportunities. Focuses on issues within circle of influence that can be automatically addressed.
## When to Use This Skill
Use at end of work session when:
- Multiple authentication or permission errors occurred
- Repeated commands suggest missing setup or automation
- Tooling/environment issues caused delays
- Pattern emerged that should be captured in skills/docs
- User explicitly requests reflection/retrospective
**When NOT to use:**
- Mid-session (wait until work complete)
- For expected development work (debugging logic, fixing tests)
- For system constraints outside control (CI/CD wait times, language limitations)
## Core Principle
**Question**: "What should the system learn from this session?"
Focus on **preventable friction** vs **expected work**:
- ✅ SSH keys not loaded → Preventable (add to shell startup)
- ✅ Commands repeated 3+ times → Preventable (create alias or add to CLAUDE.md)
- ✅ Missing environment setup → Preventable (document in AGENTS.md)
- ❌ Tests took time to debug → Expected work
- ❌ Code review iterations → Expected work
- ❌ CI/CD pipeline wait time → System constraint
## Analysis Framework
Review conversation history and todo list for:
**Tooling Issues** (high-value targets):
- Authentication failures (SSH, API tokens, credentials)
- Permission errors (file access, git operations)
- Environment setup gaps (missing dependencies, config)
- Repeated command patterns (3+ uses signals missing automation)
**Knowledge Gaps** (documentation opportunities):
- Commands not in CLAUDE.md/AGENTS.md
- Skills that should exist but don't
- Skills that need updates (new patterns, edge cases)
- Workflow improvements that should be automated
**System Components**:
- Context files: CLAUDE.md (commands), AGENTS.md (build/test commands, conventions)
- Skills: Reusable workflows and techniques
- Agent definitions: Specialized subagent behaviors
- Shell configs: Aliases, functions, environment variables
**Time Measurement**:
- Tooling friction time vs actual implementation time
- Repeated failures on same issue
- Context switches due to environment problems
**Circle of Influence**:
- Within control: Documentation, skills, shell config, automation
- System constraints: Language limitations, company policies, hardware
## Reflection Output
Produce structured analysis mapping issues to system components:
```markdown
# Session Reflection
## What Went Well
- [1-2 brief highlights]
## Preventable Issues
### Issue 1: [Brief description]
**Impact**: [Time lost / context switches / productivity hit]
**Root Cause**: [Why it happened - missing doc, setup gap, no automation]
**Target Component**: [CLAUDE.md | AGENTS.md | skill | shell config | agent]
**Proposed Action**: [Specific change to make]
**Priority**: [High | Medium | Low]
[Repeat for 1-3 high-value issues max]
## System Improvement Recommendations
For @optimize agent to implement:
1. **Documentation Updates**:
- Add [command/pattern] to [CLAUDE.md/AGENTS.md]
- Document [setup step] in [location]
2. **Skill Changes**:
- Create new skill: [skill-name] for [purpose]
- Update [existing-skill]: [specific addition]
3. **Automation Opportunities**:
- Shell alias for [repeated command]
- Script for [manual process]
## Summary
[1 sentence key takeaway]
---
**Next Step**: Run `@optimize` to implement these improvements automatically.
```
## Analysis Process
1. **Review conversation**: Scan for error messages, repeated commands, authentication failures
2. **Check todo list**: Identify unexpected tasks added mid-session, friction points
3. **Identify patterns**: Commands repeated 3+ times, similar errors, knowledge gaps
4. **Measure friction**: Estimate time on tooling vs implementation
5. **Filter ruthlessly**: Exclude expected work and system constraints
6. **Focus on 1-3 issues**: Quality over quantity - only high-impact improvements
7. **Map to system components**: Where should each fix live?
8. **Provide structured output**: Format for optimize agent to parse and execute
## Common Preventable Patterns
**Authentication**:
- SSH keys not in agent → Add `ssh-add` to shell startup
- API tokens not set → Document in AGENTS.md setup section
- Credentials expired → Document refresh process
**Environment**:
- Dependencies missing → Add to AGENTS.md prerequisites
- Docker state issues → Document cleanup commands in CLAUDE.md
- Port conflicts → Document port usage in AGENTS.md
**Documentation**:
- Commands forgotten → Add to CLAUDE.md commands section
- Build/test commands unclear → Add to AGENTS.md build section
- Setup steps missing → Add to AGENTS.md or README
**Workflow**:
- Manual steps repeated 3+ times → Create shell alias or script
- Pattern used repeatedly → Extract to skill
- Agent behavior needs refinement → Update agent definition
**Skills**:
- Missing skill for common pattern → Create new skill
- Skill missing edge cases → Update existing skill's "Common Mistakes"
- Skill references outdated → Update examples or references
## Distinguishing Analysis from Implementation
**This skill (reflect)**: Provides analysis framework and structured findings
**Optimize agent**: Takes findings and implements changes automatically
**Division of responsibility**:
- Reflect: Identifies what needs to change and where
- Optimize: Makes the actual changes (write files, create skills, update docs)
After reflection, invoke `@optimize` with findings for automatic implementation.
## Examples
### Good Issue Identification
**Issue**: SSH authentication failed on git push operations
**Impact**: 15 minutes lost, 4 retry attempts, context switches
**Root Cause**: SSH keys not loaded in ssh-agent at session start
**Target Component**: Shell config (.zshrc)
**Proposed Action**: Add `ssh-add ~/.ssh/id_ed25519` to .zshrc startup
**Priority**: High
### Pattern Worth Capturing
**Issue**: Repeatedly explaining NixOS build validation workflow
**Impact**: 10 minutes explaining same process 3 times
**Root Cause**: No skill for NixOS-specific workflows
**Target Component**: New skill
**Proposed Action**: Create `nixos-development` skill with build/test patterns
**Priority**: Medium
### Documentation Gap
**Issue**: Forgot test command, had to search through project
**Impact**: 5 minutes searching for command each time used
**Root Cause**: Test command not in AGENTS.md
**Target Component**: AGENTS.md
**Proposed Action**: Add `nix flake check` to build commands section
**Priority**: High
### Non-Issue (Don't Report)
**NOT an issue**: Debugging Nix configuration took 30 minutes
**Why**: This is expected development work. Learning and debugging configs is part of NixOS development.
**NOT an issue**: Waiting for large rebuild
**Why**: System constraint. Build time is inherent to Nix architecture.
## Balanced Perspective
**DO emphasize**:
- Preventable setup issues
- Missing documentation
- Automation opportunities
- Knowledge capture (skills, patterns)
- System improvements
**DON'T complain about**:
- Time spent on actual work (that's the job)
- Normal debugging and learning
- Inherent tool characteristics
- Company processes (system constraints)
## Integration with Optimize Agent
After reflection analysis:
1. Review reflection findings
2. Invoke `@optimize` to implement improvements
3. Optimize agent will:
- Update CLAUDE.md/AGENTS.md with commands/docs
- Create or update skills based on patterns
- Create shell aliases for repeated commands
- Generate git commits with changes
- Report what was implemented
This two-stage process:
- **Reflect**: Analysis and identification (passive, focused)
- **Optimize**: Implementation and automation (active, powerful)
## Success Criteria
Good reflection provides:
- 1-3 high-impact preventable issues (not 10+ minor ones)
- Clear mapping to system components (where to make changes)
- Specific actionable improvements (not vague suggestions)
- Honest assessment of circle of influence
- Structured format for optimize agent to parse
- Avoids suggesting we skip essential work
## Future Memory Integration
When memory/WIP tool becomes available, reflection will:
- Track recurring patterns across sessions
- Build knowledge base of improvements
- Measure effectiveness of past changes
- Detect cross-project patterns
- Prioritize based on frequency and impact
For now, git history serves as memory (search past reflection commits).

name: research-medical
description: Use when researching medical/scientific topics and encountering paywalled journals, access failures, or needing primary sources - provides strategies for PubMed Central, DOI resolution, preprint servers, and fallback approaches for medical literature access
---
# Medical Research Access
Strategies for accessing medical and scientific literature when direct web access fails or sources are paywalled.
## When to Use This Skill
**Use when:**
- Webfetch fails on medical journal sites (NIH, Nature, JAMA, NEJM, etc.)
- Research requires primary sources (studies, trials, systematic reviews)
- Need to access paywalled medical literature
- Looking for recent research not yet peer-reviewed
- Extracting citations when full text unavailable
**When NOT to use:**
- General web research (use standard webfetch)
- Medical journalism is sufficient (STAT News, MedPage Today)
- Topic well-covered in open-access sources
## Quick Reference: Access Strategies
| Source Type | Primary Method | Fallback | Notes |
|-------------|---------------|----------|-------|
| Peer-reviewed studies | PubMed Central | DOI resolution, preprints | Always check PMC first |
| Recent research | Preprint servers | Author websites | May not be peer-reviewed yet |
| Clinical trials | ClinicalTrials.gov | Trial registries | Protocol vs results |
| Meta-analyses | Cochrane Library | PubMed search | Often open access |
| Medical journalism | STAT News, Medscape | Press releases | Secondary sources |
| Guidelines | Professional societies | NIH, CDC | Usually open access |
## Access Strategies
### 1. PubMed Central (PMC) - First Stop
**Why PMC:** Free full-text archive of biomedical literature, subset of PubMed with actual paper content.
**Search approaches:**
```markdown
# Direct PMC search
https://www.ncbi.nlm.nih.gov/pmc/?term=ivermectin+COVID-19+randomized+controlled+trial
# Filters to add:
- Free full text
- Article type (Clinical Trial, Meta-Analysis, Systematic Review)
- Publication date range
```
**When webfetch fails on PMC:**
- Try PubMed instead (has abstracts even without full text)
- Search by PMID if you have it: `https://pubmed.ncbi.nlm.nih.gov/[PMID]/`
- Look for "Free PMC article" badge in PubMed results
### 2. DOI Resolution Services
**What is DOI:** Digital Object Identifier - permanent link to research papers.
**Primary resolver:**
```markdown
https://doi.org/[DOI-HERE]
Example: https://doi.org/10.1056/NEJMoa2115869
```
**When DOI resolution hits paywall:**
- Try adding DOI to Google Scholar: `https://scholar.google.com/scholar?q=[DOI]`
- Check for "All versions" link in Scholar (may include preprint or author PDF)
- Look for institutional repository versions
**Extracting DOI from citations:**
- Usually in format: `10.XXXX/journal.year.number`
- Found at end of citation or in URL
- Can search PubMed by DOI to get PMID
### 3. Preprint Servers - Recent Research
**Primary servers:**
| Server | Focus | URL Pattern |
|--------|-------|-------------|
| medRxiv | Medicine | `https://www.medrxiv.org/content/[ID]` |
| bioRxiv | Biology | `https://www.biorxiv.org/content/[ID]` |
| SSRN | Social science, econ | `https://papers.ssrn.com/sol3/papers.cfm?abstract_id=[ID]` |
**Important notes:**
- Preprints are NOT peer-reviewed
- Always note preprint status in citations
- Check if preprint later published in journal (search by title)
- Good for very recent research (last 6-12 months)
**Search strategy:**
```markdown
# Search medRxiv directly
https://www.medrxiv.org/search/ivermectin%20COVID-19
# Or use Google Scholar with "preprint" filter
site:medrxiv.org OR site:biorxiv.org [search terms]
```
### 4. Medical Journalism Without Paywalls
**Freely accessible sources:**
- **STAT News** (`statnews.com`) - High-quality medical journalism, no paywall
- **Medscape** (`medscape.com`) - Free with registration, clinical news
- **The Conversation** (`theconversation.com`) - Academic experts, open access
- **Science Daily** (`sciencedaily.com`) - Press releases and summaries
- **NIH News** (`nih.gov/news-events`) - Government research announcements
**When to use journalism vs primary sources:**
- Journalism: Background, context, expert opinions, controversy overview
- Primary sources: Specific claims, data, methodology, for fact-checking
**Citation approach:**
- Use journalism to identify key studies
- Track down primary sources for verification
- Cite primary source when making factual claims
- Cite journalism when discussing expert opinions or controversy
### 5. Clinical Trial Registries
**ClinicalTrials.gov** - Official US registry:
```markdown
https://clinicaltrials.gov/search?term=[drug/intervention]
Filter by:
- Study Status (Completed, Published)
- Study Type (Interventional)
- Study Results (Studies with Results)
```
**What you get:**
- Trial protocol and design
- Primary/secondary outcomes
- Results summary (if published)
- Links to published papers
**Other registries:**
- WHO ICTRP (international): `https://trialsearch.who.int/`
- EU Clinical Trials Register: `https://www.clinicaltrialsregister.eu/`
### 6. Professional Society Guidelines
**Often open access:**
- CDC guidelines: `cdc.gov`
- WHO guidelines: `who.int`
- NIH treatment guidelines: `covid19treatmentguidelines.nih.gov`
- Professional societies (AMA, ACP, IDSA) - check guidelines sections
**Good for:**
- Official recommendations
- Evidence summaries
- Standard of care
- Consensus positions
### 7. Google Scholar Strategies
**When direct access fails:**
```markdown
# Search with specific terms
"ivermectin" "COVID-19" "randomized controlled trial"
# Use "All versions" link to find:
- Preprint versions
- Author PDFs
- Institutional repository copies
# Filter by date range for recent research
```
**Citation extraction when full text unavailable:**
- Scholar provides formatted citations
- Shows "Cited by" count (impact indicator)
- Links to related articles
- May show abstract even without full text
### 8. Author Websites and ResearchGate
**When other methods fail:**
- Search author name + paper title
- Check university faculty pages (often have PDFs)
- ResearchGate (`researchgate.net`) - researchers share papers
- Academia.edu - similar to ResearchGate
**Caution:**
- Verify version matches published paper
- Note if it's a preprint or draft
- Check publication date
## Webfetch vs Direct Access Decision Tree
**Use webfetch when:**
- Source is known to be open access
- Medical journalism sites (STAT, Medscape)
- Government sites (NIH, CDC, FDA)
- Preprint servers
- Professional society guidelines
**Skip webfetch, use search strategies when:**
- Major journal sites (Nature, JAMA, NEJM, Lancet) - usually paywalled
- You have DOI - use DOI resolver or Scholar
- Need recent research - go to preprint servers
- Previous webfetch attempts failed on similar sources
**General agent with web search when:**
- Exploratory research (don't know specific sources yet)
- Need to identify key studies first
- Looking for expert commentary or summaries
- Building initial source list
## Citation Extraction Techniques
### When Full Text Unavailable
**From abstracts (PubMed):**
- Study design and methods
- Primary outcomes
- Sample size
- Key findings (usually in abstract)
- Limitations (sometimes mentioned)
**From press releases:**
- High-level findings
- Author quotes
- Institution and funding
- Link to actual paper (follow this)
**From systematic reviews/meta-analyses:**
- Summary of multiple studies
- Effect sizes across studies
- Quality assessments
- Usually cite all included studies (mine these)
### Citation Format Best Practices
**Minimum required:**
```markdown
Author(s). Title. Journal Year;Volume(Issue):Pages. DOI: [DOI]
```
**Enhanced format:**
```markdown
Author(s). Title. Journal Year;Volume(Issue):Pages. DOI: [DOI]. PMID: [PMID]. [Access status]
Example:
Lopez-Medina E, et al. Effect of Ivermectin on Time to Resolution of Symptoms Among Adults With Mild COVID-19. JAMA 2021;325(14):1426-1435. DOI: 10.1001/jama.2021.3071. PMID: 33662102. [Free full text via PMC]
```
**Always include:**
- DOI (for verification and access)
- PMID if available (PubMed tracking)
- Access status (open access, PMC free, paywalled)
- Preprint status if applicable
## Common Mistakes
### ❌ Giving up after first webfetch failure
**Problem:** Many medical sites block automated access or require authentication.
**Fix:** Use systematic fallback strategy:
1. Try PubMed Central search
2. Use DOI resolver if you have DOI
3. Check preprint servers
4. Search Google Scholar for alternative versions
5. Use medical journalism to identify sources, then track down primary
### ❌ Citing journalism when primary source is accessible
**Problem:** Secondary source citation when primary is available weakens credibility.
**Fix:**
- Use journalism to find studies
- Always attempt to access primary source
- Cite primary source for factual claims
- Cite journalism only for expert opinions or controversy framing
### ❌ Not noting preprint vs peer-reviewed status
**Problem:** Preprints lack peer review and may contain errors or later be contradicted.
**Fix:**
- Always check publication status
- Note in citation: "[Preprint, not peer-reviewed]"
- Search by title to see if later published in journal
- Weight peer-reviewed sources more heavily
### ❌ Ignoring "Cited by" counts and publication dates
**Problem:** May miss that study was retracted, contradicted, or superseded.
**Fix:**
- Check "Cited by" in Google Scholar
- Look for retractions or corrections
- Check for more recent systematic reviews
- Note if study is outlier vs consensus
### ❌ Using only abstracts for detailed claims
**Problem:** Abstracts omit important limitations, methods details, and context.
**Fix:**
- Use abstract for high-level findings only
- For specific claims, need full text
- If full text unavailable, note limitation: "[Based on abstract only]"
- Look for systematic reviews that analyzed full text
### ❌ Not tracking access failures for optimization
**Problem:** Repeated failures on same source types waste time.
**Fix:**
- Note which sources consistently fail webfetch
- Build project-specific access strategy
- Document successful access patterns
- Update AGENTS.md with project-specific guidance
## Real-World Impact
**Session context:** Pierre Kory/ivermectin research encountered 4 failed web access attempts (NIH, FDA, Nature, JAMA, MedPage Today), limiting source diversity to 2 primary sources.
**With this skill:**
- PubMed Central search would provide free full-text access to key trials
- DOI resolution would access Nature and JAMA papers via alternative routes
- Preprint servers would surface early ivermectin research
- Medical journalism (STAT News) would provide controversy context without paywall
- Clinical trial registries would provide TOGETHER trial and other RCT data
**Expected improvement:** 5-8 accessible sources instead of 2, with mix of primary sources and expert commentary.
## Workflow Integration
### Research Session Startup
1. **Identify topic and key terms**
2. **Start with PubMed Central search** (free full text)
3. **Check for systematic reviews** (summarize evidence)
4. **Search preprint servers** (recent research)
5. **Use medical journalism** (context and expert opinions)
6. **Track citations** (DOI, PMID, access status)
### When Webfetch Fails
1. **Don't retry same URL** - move to fallback strategy
2. **Extract DOI from citation** - use DOI resolver
3. **Search PubMed by title** - may find PMC version
4. **Check Google Scholar** - look for "All versions"
5. **Note failure** - document for future optimization
### Citation Verification
1. **Have DOI or PMID** - verify via PubMed lookup
2. **Check publication status** - preprint vs peer-reviewed
3. **Look for retractions** - search "[title] retraction"
4. **Note access method** - for reproducibility
5. **Capture full citation** - author, title, journal, DOI, PMID
## Additional Resources
**PubMed search tips:**
- Use MeSH terms (Medical Subject Headings) for precise searches
- Combine with Boolean operators (AND, OR, NOT)
- Use filters: Free full text, Article type, Publication date
- Save searches for repeated use
**Understanding study types:**
- RCT (Randomized Controlled Trial) - gold standard
- Systematic Review/Meta-Analysis - synthesis of multiple studies
- Cohort Study - observational, follows groups over time
- Case-Control Study - compares cases to controls
- Case Series/Report - descriptive, lowest evidence level
**Red flags in research:**
- Preprint only (not peer-reviewed)
- Retracted or corrected
- Conflicts of interest not disclosed
- Small sample size with strong claims
- Outlier findings not replicated

# Research Skill
Quick reference for conducting deep research with proper citations, concise output, and novel insights across any domain.
## When to Use This Skill
- Investigating technical topics (APIs, frameworks, algorithms)
- Understanding psychological or human factors
- Exploring creative writing techniques or artistic approaches
- Synthesizing information from multiple disparate sources
- Making connections between different domains
- Gathering authoritative sources for decision-making
**When NOT to use:**
- Simple factual lookups (use direct search instead)
- Code implementation (use coding agents)
- Quick reference checks (use man pages directly)
## Citation Format Reference
### Web Sources
```
<source url="https://example.com/article" title="Article Title">Specific claim or finding from the source</source>
```
### Academic Papers
```
<source url="https://arxiv.org/abs/2210.03629" title="ReAct: Synergizing Reasoning and Acting">Quantitative finding or key insight</source>
```
### Local Files
```
<source url="file:///path/to/file.md" title="filename.md">Code snippet or configuration detail</source>
```
### Man Pages
```
<source url="man://grep" title="grep(1) manual">Command behavior or flag description</source>
```
### Multiple Sources for Same Claim
```
<source url="https://source1.com" title="First Study">Initial finding</source> corroborated by <source url="https://source2.com" title="Second Study">confirming evidence</source>
```
## Output Style Guide
| Good (Concise Paragraphs) | Bad (Bullets/Verbosity) |
|---|---|
| The STORM paper introduces a multi-agent system for comprehensive research. <source>Finding</source>. This approach yields Wikipedia-quality output. | It is important to note that:<br>- STORM uses agents<br>- Perhaps it works well<br>- Furthermore, one might consider... |
| Direct statement with citation. | "It seems that this might be useful..." |
| 2-4 sentence paragraphs. | Wall of text or excessive bullets. |
## ReAct Research Loop
**Pattern for iterative research:**
1. **Thought**: "I need to understand X. Sources to check: Y, Z."
2. **Action**: `curl https://docs.example.com/api` or `man command` or `rg "pattern"`
3. **Observation**: "Found A, B, C. Still missing D."
4. **Thought**: "Need to refine search for D."
5. **Action**: New search with refined query
6. **Observation**: "Now have complete picture."
Repeat until sufficient evidence gathered.
## Making Cross-Domain Connections
### Technique: Analogy Mapping
1. Identify core mechanism in source domain
2. Find parallel structure in target domain
3. Map relationships explicitly
4. Test if analogy reveals new insights
**Example**: ReAct pattern (technical) ↔ Expert problem-solving (psychology)
- Both externalize thinking
- Both enable error detection
- Both reduce cognitive load
- Connection reveals *why* ReAct works
### Technique: Pattern Recognition
Look across sources for:
- Recurring themes or principles
- Shared constraints or trade-offs
- Similar solution approaches
- Common failure modes
### Technique: Contrast Analysis
When sources disagree:
- Identify specific points of tension
- Examine underlying assumptions
- Consider context differences
- Synthesize higher-level insight
## Research Tool Usage
### Web Research
```bash
# Fetch documentation
curl -s https://docs.example.com/api | grep "pattern"
# Download paper
wget https://arxiv.org/pdf/2210.03629.pdf
# Search with specific terms
curl -s "https://api.example.com/search?q=term"
```
### Man Pages
```bash
# Full manual
man grep
# Search within man page
man grep | grep -A 5 "pattern"
# List all man pages for command
man -k search_term
```
### Code/File Research
```bash
# Find implementations
rg "function_name" --type rust
# Search with context
rg "pattern" -A 3 -B 3
# Find files by name
find . -name "*.md" -type f
```
## Common Mistakes
**Mistake: Uncited claims**
```
❌ "The ReAct pattern improves performance significantly."
✅ "The ReAct pattern improves performance significantly. <source>specific metric</source>."
```
**Mistake: Verbose hedging**
```
❌ "It seems that perhaps one might consider that this could potentially..."
✅ "This approach increases success rates by 34%."
```
**Mistake: Bullet point overload**
```
❌ Long lists of disconnected bullets
✅ 2-4 sentence paragraphs that flow coherently
```
**Mistake: Missing cross-domain insights**
```
❌ Only technical analysis without broader connections
✅ "This pattern mirrors cognitive psychology research on expert problem-solving..."
```
**Mistake: No verification step**
```
❌ Output without checking citation coverage
✅ Self-check: Every claim cited? Format correct? Under 500 words?
```

## Domain-Specific Notes
### Technical Research
Focus on: Implementation details, performance metrics, trade-offs, compatibility, version-specific behavior
### Psychology/Human Factors
Focus on: User studies, cognitive principles, behavioral patterns, accessibility, mental models
### Creative Writing
Focus on: Techniques from literature, stylistic approaches, examples from published works, craft advice from authors
### Science/Research
Focus on: Peer-reviewed sources, methodology, empirical findings, replication status, statistical significance
## Example: Good Research Output
**Query**: How does the ReAct reasoning pattern work?
**Output**:
The ReAct pattern addresses a key limitation in language model task-solving by interleaving reasoning traces with tool actions. <source url="https://arxiv.org/abs/2210.03629" title="ReAct: Synergizing Reasoning and Acting in Language Models">ReAct agents achieve 34% higher success rates on ALFWorld tasks and 10% improvement on HotpotQA compared to baselines</source>. The core mechanism involves explicit Thought-Action-Observation loops where the model verbalizes its reasoning before taking each action, then updates its understanding based on observations.
This architecture mirrors findings from cognitive psychology on expert problem-solving. <source url="file://references/cognitive-science.md" title="Expert Problem Solving Research">Experts externalize their thinking through verbal protocols, which reduces cognitive load by offloading working memory to external representations</source>. By forcing LLMs to "think aloud," ReAct essentially implements this expert strategy in artificial systems.
The practical implication is clear: tasks requiring multi-step reasoning benefit from explicit trace generation. ReAct excels when error recovery matters, since failed actions produce observations that redirect reasoning. For simple, single-step tasks, the overhead isn't justified.
