## 🎯 Next Steps

**Immediate:** Install dependencies and start Phase 1  
**Location:** See IMPLEMENTATION_PLAN.md - Phase 1, Step 1.2

```bash
cd llmemory
npm install                      # Install dependencies
node src/cli.js --help          # Test prototype (will work after npm install)
```

**Then:** Implement database layer (Step 1.2)
- Create src/db/connection.js
- Create src/db/schema.js
- Create src/db/queries.js

## 📚 Key Documents

**For Overview:**
- Start with README.md

**For Implementation:**
1. SPECIFICATION.md - What to build
2. IMPLEMENTATION_PLAN.md - How to build it (with checkboxes!)
3. ARCHITECTURE.md - Why it's designed this way

**For Quick Start:**
- NEXT_SESSION.md - Everything you need to continue

## 🧪 Testing Commands

```bash
# After npm install, these should work:
node src/cli.js --help
node src/cli.js store "test" --tags demo
node src/cli.js search "test"
node src/cli.js --agent-context
```

Currently shows placeholder output. Full implementation in Phase 1.

## 💡 Design Highlights

**Three-Phase Approach:**
1. Phase 1: MVP with LIKE search (<500 memories, <50ms)
2. Phase 2: FTS5 upgrade (10K memories, <100ms)
3. Phase 3: Fuzzy matching (100K+ memories, <200ms)

**Key Technologies:**
- SQLite with better-sqlite3
- Commander.js for CLI
- FTS5 for full-text search
- Trigram indexing for fuzzy matching

**Architecture:**
- CLI Layer (Commander.js)
- Search Layer (LIKE → FTS5 → Fuzzy)
- Storage Layer (SQLite)

## 🎓 Learning Resources

Included in documentation:
- SQLite FTS5 algorithm explanation
- BM25 relevance ranking formula
- Levenshtein edit distance implementation
- Trigram similarity calculation
- Memory format best practices

## 🚀 Timeline Estimate

- Phase 1 (MVP): 12-15 hours
- Phase 2 (FTS5): 8-10 hours
- Phase 3 (Fuzzy): 8-10 hours
- **Total: 28-35 hours to full implementation**

## ✨ Project Quality

**Documentation Quality:** ⭐⭐⭐⭐⭐
- Comprehensive technical specifications
- Step-by-step implementation guide
- Algorithm pseudo-code included
- Examples and anti-patterns documented

**Code Quality:** N/A (not yet implemented)
- Prototype validates CLI design
- Ready for TDD implementation

**Architecture Quality:** ⭐⭐⭐⭐⭐
- Phased approach (MVP → production)
- Clear migration triggers
- Performance targets defined
- Scalability considerations

## 🔍 Notable Features

**Agent-Centric Design:**
- Grep-like query syntax (familiar to AI agents)
- `--agent-context` flag with comprehensive guide
- Auto-extraction of `*Remember*` patterns
- Token-efficient search results

**Production-Ready Architecture:**
- Three search strategies (LIKE, FTS5, fuzzy)
- Intelligent cascading (exact → fuzzy)
- Relevance ranking (BM25 + edit distance + recency)
- Expiration handling
- Migration strategy

## 📝 Notes for Implementation

**Start Here:**
1. Read NEXT_SESSION.md (15 min)
2. Review SPECIFICATION.md (30 min)
3. Follow IMPLEMENTATION_PLAN.md Step 1.2 (database layer)

**Testing Strategy:**
- Write tests first (TDD)
- Use :memory: database for unit tests
- Integration tests with temporary file
- Performance benchmarks after each phase

**Commit Strategy:**
- Update checkboxes in IMPLEMENTATION_PLAN.md
- Clear commit messages (feat/fix/test/docs)
- Reference implementation plan steps

**Status:** Phase 0 Complete ✅  
**Ready for:** Phase 1 Implementation  
**Estimated Completion:** 12-15 hours of focused work
