What the TDD skill actually does

Enforces the Iron Law: no production code without a failing test first. No exceptions.

The TDD skill enforces a single, absolute rule: no production code can be written until a failing test for that code exists and has been observed failing. This is the Iron Law of TDD, and the skill treats it as non-negotiable.

The core principle is that if you didn't watch the test fail, you don't know if it tests the right thing. Tests written after code pass immediately, which proves nothing. The skill explains why the order matters, walks you through the Red-Green-Refactor cycle, and dismantles the most common rationalizations for skipping the test-first step.

The Red-Green-Refactor Cycle

Five mandatory phases, each with a verification step.

01

RED: Write the Failing Test

Write one minimal test for the next behavior. It must be for real code (no mocks unless unavoidable), test one thing, and have a clear name.

02

Verify RED: Watch It Fail

Run the test and confirm it fails because the feature is missing, not because of a typo or error. This step is mandatory. Never skip it.

03

GREEN: Write Minimal Code

Write the simplest code that makes the test pass. Don't add features, refactor other code, or improve beyond what the test requires.

04

Verify GREEN: Watch It Pass

Run the test again. Confirm it passes and that no other tests broke. Output must be pristine: no errors, no warnings.

05

REFACTOR: Clean Up

After green only: remove duplication, improve names, extract helpers. Keep tests green. Don't add new behavior.

Verification Checklist

Every box must be checked before marking work complete.

  • Every new function or method has a test
  • You watched each test fail before implementing
  • Each test failed for the expected reason (feature missing, not a typo)
  • You wrote the minimal code to pass each test
  • All tests pass
  • Output is pristine: no errors, no warnings
  • Tests use real code (mocks only if unavoidable)
  • Edge cases and error paths are covered

Frequently Asked Questions

Everything you need to know about installing and running these Claude Skills.

The TDD skill enforces strict test-driven development inside Claude Code. Run /coding test-driven-development and Claude will require a failing test before writing any production code, walk you through the Red-Green-Refactor cycle, dismantle every rationalization for skipping the test-first step, and verify a final checklist before marking work complete.
If you didn't watch the test fail, you don't know if it tests the right thing. A test that passes immediately might be testing the wrong behavior, testing implementation instead of behavior, or missing the edge case it was supposed to catch. Watching the failure proves the test is actually covering the missing feature.
The skill recognizes three explicit exceptions: throwaway prototypes, generated code, and configuration files. For anything else, the Iron Law applies. The skill also says that thinking 'skip TDD just this once' is rationalization and lists this as a red flag requiring you to stop and start over.
Tests written after code verify what the existing implementation does. Tests written first specify what the implementation should do. The order changes what the tests actually prove. Tests-after will pass even if the code has subtle bugs in untested paths. Tests-first discover requirements and edge cases before implementation, not after.
The skill's guidance is to add tests when improving existing code. If you're touching a function that has no tests, write a test for the existing behavior first, watch it pass, then write a test for the new behavior and watch it fail before adding the feature.
