tdd-engineer skillA

tdd-engineer is agent-read markdown (skill) from felvieira/claude-skills-fv: Test-Driven Development com red-green-refactor enforced. Use quando construir feature ou fix de bug usando TDD, mencionar "red-green-refactor", quiser tracer bullets, ou pedir desenvolvimento test-first. Combate o anti-padrao "horizontal slicing" (escrever todos os testes antes de toda a implementacao). Trigger em: "tdd", "test-first", "red-green-refactor", "tracer bullet", "behavior test", "integration test", "tdd deep module", "interface design test"..

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

Latest version
mdr add felvieira/claude-skills-fv/tdd-engineer@git:20260909.9a9f0e4
Exact content

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.
