implement-to-pass

To pass failing unit tests, this Skill identifies the smallest code changes needed to satisfy the red test suite and applies them to transition to the green phase without scope creep. It implements only what the tests require.

The minimum code to turn red tests green is the exact logic required to satisfy assertions. This Skill isolates failing conditions and applies targeted implementations to pass tests while preventing regression in the suite.

To prevent scope creep when implementing for failing tests, this Skill applies built-in guardrails that restrict changes to only what is necessary for passing the test suite, avoiding unnecessary refactoring or feature additions during the green phase.

Yes, this approach works for both unit and integration tests in typical software projects. It applies the red-to-green transition across test suites by implementing only the minimum code necessary for each failing condition.

Use a minimum implementation approach for failing tests during the green phase of a TDD workflow. After writing a failing test, run this step to implement just enough code to pass the suite before moving to the refactor phase.

Implementing more than the test requires causes regression by introducing untested code paths. This Skill addresses that by applying only the minimal changes needed to convert failing tests to passing tests, adding guardrails to prevent scope creep.
