Why does this skill require me to watch a test fail?

Watching a test fail (the RED phase) is mandatory because it proves the test is actually testing the new behavior and isn't passing accidentally due to a false positive or existing code.

How does this skill handle bug fixes?

For every bug fix, the skill requires writing a failing test that reproduces the reported issue. This ensures the fix is accurate and provides a permanent regression test.

What is the 'Iron Law' in this TDD skill?

The Iron Law mandates that no production code can be written without a failing test existing first. If code is written before a test, it must be deleted and rewritten following the TDD cycle.

Can I skip TDD for simple tasks or prototypes?

The skill encourages TDD for almost all scenarios including refactoring. Exceptions like throwaway prototypes or configuration files are only permitted with explicit approval from the human partner.

Seguridad y Pruebas

Enforces a strict Red-Green-Refactor workflow to ensure all production code is verified by failing tests before implementation.

Acerca de

The Test-Driven Development (TDD) skill embeds a rigorous engineering discipline into Claude's workflow, mandating the 'Iron Law' that no production code is written without a preceding failing test. It guides the AI through the complete Red-Green-Refactor cycle, ensuring that every feature, bug fix, and refactor is driven by behavioral requirements rather than implementation bias. By focusing on minimal code solutions and mandatory failure verification, this skill helps developers eliminate technical debt, discover edge cases early, and maintain a high-confidence codebase where every line of code is purposeful and verified.
