# Build and Fix

Incrementally fix Python type and lint errors:

1. Run checks:
   - mypy src/ (type checking)
   - ruff check . (linting)
   - pytest (tests)

2. Parse error output:
   - Group by file
   - Sort by severity

3. For each error:
   - Show error context (5 lines before/after)
   - Explain the issue
   - Propose fix
   - Apply fix
   - Re-run check
   - Verify error resolved

4. Stop if:
   - Fix introduces new errors
   - Same error persists after 3 attempts
   - User requests pause

5. Show summary:
   - Errors fixed
   - Errors remaining
   - New errors introduced

Fix one error at a time for safety!
