tdd

Overview

Use this as the Codex-first TDD workflow. It should enforce red-green-refactor and keep test-first behavior real instead of decorative.

Inputs

• target feature or file
• optional coverage target

Codex Workflow

Source references:

• .claude/commands/tdd.md

1. write the failing test first
2. confirm the failure
3. implement the minimum change to pass
4. refactor safely
5. re-run broader validation

Expected Output

• failing test
• minimal fix
• updated test coverage

Guardrails

• do not write the implementation first
• keep the change minimal until the failing behavior is covered
