Grill (orchestrator interview)

1. Goal: "What are you trying to accomplish?"
2. Success criteria: "Describe how we know the loop succeeded."
3. Success type: choose from test, build, lint, command, fileExists, oracle, observer, manual. For CLI steps provide successCommand; for file detection provide successPath.
4. Execute agent: fixer / designer / explorer / librarian
5. Verify agent: oracle / observer / test
6. Max attempts (default 3)
7. Optional context files: which files or directories should be read before execution?

Loop Monitor

• Listen to callbacks:
  • onLoopComplete(loopID, success) → report final outcome
  • onEscalated(loopID, reason) → escalate to human
  • onManualReview(loopID, reason) → prompt human to approve/fail and call resolveManualReview(loopID, passed, reason)
• Show current state and attempt count on each callback
• For manual verification, present the failure reason before asking for pass/fail
• If human forces cancellation, call cancel(loopID) through the orchestrator

Notes

• Manual verification is the minimal on-ramp (autoresearch pattern). It pauses the loop until resolveManualReview is called. Do not auto-resolve.
• BackgroundJobBoard signals (totalErrors, timeoutCount) are already baked into the runtime.
