Behavior first
Use when implementing features or fixing bugs with tests. Applies red-green-refactor, behavior-focused tests, public-interface testing, and small vertical slices. Trigger when the user says TDD, tests, implement with tests, make it stable, or fix with regression coverage.From its SKILL.md

Behavior First
中文核心：测行为，不拜实现。
Principles
- Test observable behavior through public interfaces.
- Avoid tests that depend on private implementation details.
- Work in vertical slices: one behavior, one test, one minimal implementation.
- Refactor only after tests are green.
Workflow
- Inspect existing test style and commands.
- Identify the public interface or user-visible behavior.
- Write one failing test for one behavior.
- Implement the smallest code needed to pass.
- Repeat for the next behavior.
- Refactor after green.
- Run relevant verification.
Test Quality
Good tests:
- read like specifications
- survive internal refactors
- fail when behavior breaks
Bad tests:
- mock internal collaborators unnecessarily
- assert private function shape
- pass while user behavior is broken
Output
End with:
- behavior implemented
- tests added or changed
- verification command and result
- known gaps, if any
