## 🚀 Next Session: Week 2 Day 3 (Go Parser Setup)

### Task 4: Go Parser Setup (2-3 hours)
**Objective**: Add Go symbol extraction support

**Steps**:
1. Install `tree-sitter-go`
2. Investigate Go AST structure
3. Create Go test fixtures (3 files: sample.go, empty.go, unicode.go)
4. Implement `GoParser` in parser.py
5. Implement `GoSymbolExtractor` in symbol_extractor.py
6. Add comprehensive tests (target: 20+ tests)
7. Update documentation

**Acceptance Criteria**:
- [ ] tree-sitter-go installed
- [ ] GoParser implemented
- [ ] GoSymbolExtractor implemented
- [ ] 20+ tests passing (100%)
- [ ] Coverage > 90%
- [ ] Type checking passes
- [ ] Linting passes
- [ ] Support: functions, methods, structs, interfaces

## 🐛 Known Issues

### Non-blocking
1. **parser.py coverage**: 0% (tested indirectly)
2. **JSDoc extraction**: Not implemented (returns None)
3. **Nested arrow functions**: Not fully extracted

### No Issues
- All tests passing
- No type errors
- No linting issues

---

## 💡 Technical Debt

### Low Priority
1. Direct unit tests for parser.py
2. Improve signature extraction robustness
3. Full nested function extraction

### Future Enhancements
1. JSDoc parsing (Week 2 Day 3+)
2. TypeDoc parsing (with TypeScript)
3. Multi-file symbol resolution
4. Incremental indexing optimization
