TDD Implementer

What problem does it solve?

This Skill enforces strict Test-Driven Development (TDD) practices, ensuring high-quality, well-tested code from the start. It eliminates the common pitfalls of writing tests after code, leading to more robust, maintainable, and bug-free software.

Core Features & Use Cases

• Automated TDD Cycle Enforcement: Guides the development through the mandatory RED (write failing tests), GREEN (implement minimum code), and REFACTOR (improve quality) phases.
• Worktree-Isolated Implementation: Each subtask is developed in its own dedicated Git worktree, preventing conflicts and enabling safe, parallel development.
• Mandatory Coverage Gates: Enforces strict code coverage thresholds (e.g., 80% line, 70% branch) before a task can be marked complete, guaranteeing thorough testing.
• Use Case: When starting a new feature, activate this skill to automatically set up the TDD environment, guide you through writing tests first, and ensure your code meets all quality standards before integration.
