▸ 精选理由

让代理在可验证的短回路中稳步推进功能与修复，提升代码可靠性。

这个 Skill 做什么

以红-绿-重构循环驱动实现：先写失败测试，再实现最小改动并重构代码。

先写一个会失败的测试（red），再做最小改动让测试通过（green），最后把代码重构干净（refactor）。适合在实现新功能或修 bug 且对正确性有要求时使用。特别之处是用失败测试把目标定死，反馈最快、能防止过度设计，常见术语有 TDD、red-green-refactor。

▸ 展开 SKILL.md 英文原文

Drive a change through a red-green-refactor loop - failing test first, minimal code to pass, then clean up. Use when implementing a feature or fixing a bug where correctness matters and a test can pin the behavior. Says "TDD", "test first", "red green refactor", "write the test first".

# tdd

The agent codes better with a tight feedback loop than with a long
specification. A failing test is the tightest loop there is: it states the
target, and the target either goes green or it does not.

## The loop

1. **Red.** Write one failing test that states the next slice of behavior.
   Run it. Confirm it fails for the right reason - a test that passes before
   you write the code is testing nothing. If it errors instead of failing on
   the assertion, fix the test setup first.
2. **Green.** Write the least code that makes the test pass. Not the general
   solution, not the abstraction - the minimal move. Run the test. Green.
3. **Refactor.** Now clean up with the test as a net: re
