Use when the user asks to add, implement, create, support, enable, expose, integrate, or build a new capability, API, UI behavior, command, option, workflow, or product behavior in a codebase using strict test-driven development. This skill guides feature development through Red → Green → Refactor by framing the requested behavior, writing or updating tests before production code, confirming meaningful failure, implementing the smallest passing change, refactoring only after green, and reporting
2 of 22 test cases passed with the skill.

A newer attempt on gemini-3.6-flash on 10/2/2026 did not produce a publishable comparison (not comparable). The snapshot above is the previously measured run.
A test case the skill fixed. Same model, same prompt, with and without the skill.
You just finished implementing a rate-limiting middleware feature with targeted unit tests passing. Outline the broader verification steps to run next.
