Implementation Methodology

Implement the specified task using the codagent:implement-with-tdd skill.

Implement exactly what the task specifies — no extra features, refactoring, or improvements beyond scope. Follow existing code patterns and conventions.

Self-Review

After implementation is complete, perform a structured self-review:

1. Is every scenario from the task spec implemented?
2. Are there any changes not justified by the task spec?
3. Are all success criteria met?
4. Do all tests and linters pass?
