Implements the minimal code necessary to move from failing tests to a passing state following TDD principles.
The tdd-green skill is a specialized utility for Claude Code designed to automate and guide the second stage of the Test-Driven Development (TDD) cycle. It focuses exclusively on achieving a 'green' test state by employing strategies like 'Faking It' with hard-coded values or using 'Obvious Implementation' for trivial logic. By prioritizing speed and simplicity over architectural perfection, this skill ensures that developers stay focused on passing tests without succumbing to premature optimization or over-engineering, creating a solid foundation for the subsequent refactoring phase.
