name	tdd
description	Quality phase. Enforces a strict Red-Green-Refactor loop. Trigger: "/tdd", "build this using TDD", "write tests first".

TDD Skill

Follow the Red-Green-Refactor methodology for every feature or bug fix.

The Loop

1. RED: Write a failing test that defines the expected behavior.
2. GREEN: Write the minimum code necessary to make the test pass.
3. REFACTOR: Clean up the code while keeping the test green.

Rules

• Never write implementation code without a failing test first.
• One Test at a Time: Focus on the smallest unit of behavior.
• Verification: Run the test suite after every step.

Benefits

• 100% test coverage for new logic.
• Documented behavior through tests.
• Prevents regressions from the start.
