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.

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.
