Quick Start for New Session

1. Verify Current State

# Navigate to project root (use your actual path)
# Windows: cd C:\path\to\agentic-coder
# Linux/Mac: cd /path/to/agentic-coder
cd <project-root>

git status
git log --oneline -5

2. Run Tests

cd backend
python test_phase6.py  # Phase 6 tests
pytest tests/ -v       # Full test suite

3. Check ROADMAP for Next Steps

  • Read docs/ROADMAP.md for Phase 7 (MCP Integration) details
  • Review ## Planned Phases section

Pending Tasks

  • Push Phase 5 and Phase 6 commits to origin
  • Start Phase 7 (MCP Integration) if requested
  • Consider Phase 8 (Multi-Agent Collaboration) for future

Notes for Next Session

  1. Phase 6 is complete and tested - All 4 tests pass
  2. Two commits unpushed - User may want to push or review first
  3. Phase 7 (MCP) is the next logical step
  4. RAG infrastructure exists - ChromaDB, CodeIndexer, ConversationIndexer are ready
  5. Test coverage: 262+ tests passing
