Gemini CLIAbout this skill
Test-Spec Driven Development (TSDD): tests are the durable specification, TDD is the operating discipline, prose carries only Why, and CLAUDE.md stays a navigation map. Load before production code, tests, ADRs, architectural decisions, CLAUDE.md edits, or any durable prose artifact that would duplicate tests or code. Also load when the user asks to write tests or define test behavior before implementation, including "test 書いて", "test 書いて", "テスト書いて", "pytest", "テスト環境", "TSDD", "Test-Spec Driven Development", "TDD で実装", "ADR を書いて", "decision record", or "executable specification".
