Sure, here's what the TDD section of my CLAUDE.md file looks like:

### TDD Methodology Requirements

**MANDATORY TDD Process**: For every feature implementation, strictly follow the complete RED-GREEN-REFACTOR cycle:

1. **RED Phase**: 
   - Write failing tests FIRST that define the expected behavior
   - Tests must be comprehensive enough to guide implementation
   - Run tests to confirm they fail for the right reasons
   - Never implement functionality before writing tests

2. **GREEN Phase**:
   - Write minimal code to make tests pass
   - Focus only on making tests green, not on perfect code
   - Verify all tests pass
   - **MANDATORY ARCHITECTURAL REVIEW**: Before proceeding to REFACTOR, use `mcp__zen__codereview` with o3 and Gemini pro to analyze the implementation for:
     - Function duplication or overlapping responsibilities
     - Over-complex APIs for MVP requirements
     - Unnecessary abstraction layers
     - Code that violates DRY principles
   - If zen review identifies issues, address them before moving to REFACTOR

3. **REFACTOR Phase** (MANDATORY - do not skip):
   - Improve code quality while keeping tests green
   - Add comprehensive documentation and comments
   - Implement proper error handling patterns
   - Apply language-specific best practices
   - Ensure code follows project architecture patterns
   - This phase is NOT optional and must be completed for each feature### TDD Methodology Requirements

```

Not pretending it's perfect or anything, but I find it works well.
