Features built from approved, testable specs.
Guides feature development so implementation follows written requirements and tests trace to acceptance criteria.
When to use it
Use when the user requests specifications before code, acceptance criteria, feature planning, tests generated from specifications, or spec-first development.
It changes how the agent develops project features by requiring a written, reviewed, approved specification before implementation.
What you provide
Requires Python 3 to run the bundled validation and test-extraction scripts; the scripts use only the standard library.
Hands off to this skill after generating test stubs for implementation discipline, coverage analysis, and framework-specific test patterns; whether installation is required is unstated.
