About this template

Test-driven development split between two agents: one only writes tests, the other only writes the code that makes them pass. Neither can quietly weaken the other's work.

What's inside

  • Test writer (Claude Code) leads: writes the next failing test, watches it fail, then asks the implementer to make it pass.
  • Implementer (Codex CLI) writes the simplest production code for exactly that test.
  • Test runner: a shell both agents run the suite in.
  • test-driven-development skill (from skills.sh): the red, green, refactor discipline both agents can load.

How to use

  1. Import into your project.
  2. Describe the feature in the Test writer's pasted prompt and press Enter.
  3. Each cycle ends on a green suite; stop it whenever you have enough.
