Builder + Checker Agent Loop That Self-Fixes Until All Tests Pass

◇ Could this help me?

Yes: The Builder + Checker loop with stop rules is directly applicable to this project and any Claude Code workflow. General Claude Code update. Implement this pattern for any feature development cycle.

✦ Walkthrough+10 xp / step

Set up a Builder + Checker agent loop in Claude Code:
Create a Builder agent: its only job is to write and fix code.
Create a Checker agent: its only job is to run tests, type checks, and linting, then report exactly what failed.
Keep them separate: the same agent that writes code cannot reliably check its own work.
Create an orchestrator command that chains them: Builder implements → Checker runs → if all green, stop; if failures, send back to Builder → repeat.
Add stop rules: (a) max 5 cycles: if not fixed after 5, a human must intervene; (b) stop immediately if a fix breaks something previously passing (regression detected).
Without stop rules, agents will start weakening tests to fake a pass.

Set up a Builder + Checker agent loop for this project: create a Builder agent for writing/fixing code and a Checker agent for running tests/linting. Add an orchestrator that loops them with a max 5-cycle stop rule and an immediate stop on regression. Show me the exact commands.
