About test-driven-development

T

test-driven-development

Drives development with tests using the red-green-refactor loop

test-driven-development is an agent skill from Addy Osmani's agent-skills collection that drives development with tests using the red-green-refactor loop. The rule is to write a failing test before writing the code that makes it pass. For a bug fix, the bug is reproduced with a test before any fix is attempted. The skill's view is that tests are proof, and that seems right is not the same as done. It argues that a codebase with good tests is a strength for an AI agent, and one without tests is a liability. The skill applies when implementing any new logic or behavior, fixing any bug, which it calls the Prove-It pattern, modifying existing functionality, adding edge case handling, and making any change that could break existing behavior. It does not apply to pure configuration, documentation or static content changes with no behavioral impact. It begins by discovering the project's testing stack. For browser-based changes, it points to combining test-driven work with runtime checks through Chrome DevTools MCP. The skill is listed on skills.sh, with its security audit results shown there. It suits developers and agents who want changes proven by tests before they are trusted.
