TDD (Test-Driven Development)

Guide the Red-Green-Refactor cycle and pragmatic testing strategy. "Write tests. Not too many. Mostly integration."

Initial context received via slash: $ARGUMENTS

If $ARGUMENTS is filled (e.g., module name, feature description), use as starting point. If empty, ask what will be tested.

Language

Write artifacts and test descriptions in the user's language. When in doubt, ask. Test code itself (function names, assertions) stays in English.

Project root

This skill writes artifacts at paths relative to the project root (the repo where the work happens), not the agent's current working directory.
