## 🎯 Key Outcomes

### Strategic Decisions

**1. Feature Priority: Repository Map First**
- **Why**: Closes competitive gap with Aider/Devin/Cursor
- **Impact**: 80% reduction in manual KB entry time
- **Differentiator**: High technical barrier = competitive moat
- **Future**: Enables ML-powered features (estimation, recommendations)

**2. Phased Language Rollout**
- **v0.11.0**: Python only (60-70% user coverage)
- **v0.11.1**: + JS/TS (90% user coverage)
- **v0.12.0**: + Go, Rust (95% user coverage)

**3. Transparent Auto-Indexing**
- **Default**: Automatic indexing (opt-out available)
- **Privacy**: 100% local, no cloud
- **Control**: Easy to disable, inspect, delete
- **Philosophy**: "Transparent Yet Controllable"

### First Development Session Goals

**Estimated Time**: 3-4 hours

**Tasks**:
1. Create feature branch: `feature/v0.11.0-repository-map`
2. Set up directory structure:
   ```
   clauxton/intelligence/
   ├── __init__.py
   ├── repository_map.py
   └── symbol_extractor.py

   tests/intelligence/
   ├── __init__.py
   ├── test_repository_map.py
   └── test_symbol_extractor.py
   ```
3. Implement RepositoryMap skeleton:
   - `__init__()` - Initialize with root directory
   - `index()` - Basic file scanning
   - `search()` - Stub for symbol search
4. Implement PythonSymbolExtractor:
   - tree-sitter integration
   - Extract functions and classes
   - Extract docstrings
5. Write initial tests:
   - Test RepositoryMap instantiation
   - Test file scanning
   - Test symbol extraction (5+ tests)

**Success Criteria**:
- ✅ `RepositoryMap()` can be instantiated
- ✅ Basic file scanning works (respects .gitignore)
- ✅ tree-sitter extracts Python symbols
- ✅ 10+ tests passing
- ✅ Code passes mypy and ruff
