writing-tests skillA

writing-tests is agent-read markdown (skill) from cristhianzl/claude-skills-czl: Write unit, integration, and E2E tests that follow the testing pyramid, the Arrange-Act-Assert pattern, the should_X_when_Y naming convention, and meet a 75% (target 80%) branch coverage gate per supported OS. Use when the user asks to write tests, add coverage, build a test suite, fix flaky tests, or verify a feature with tests. For TDD bug fixes use fixing-bugs; for TDD feature work use developing-features-tdd..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
