Gemini CLIAbout this skill
Use whenever code is about to be written or modified as part of a spec-driven implementation — whole-system or subsystem. Trigger on phrases like "実装する", "コードを書く", "TDD で進めて", "テスト先に書く", "implement this", "write the code", "let's TDD this". This skill is a REQUIRED SUB-SKILL of spec-coexist:implementing-from-spec and spec-coexist:revising and MUST halt if a failing test does not exist before production code is written. Carves out legacy/spike/notebook/config/docs via references/negative-triggers.md.
