LOOP ENGINEERING

An agent loop calls the model, runs tools, feeds results back and repeats until a stop rule fires. Defaults vary: 20 steps, 25 super-steps, 5, 10 or no cap.

Loop engineering patterns: plan/act/verify cycles, convergence criteria, retries, budget-bounded loops, and loop-until-dry, so agents stop when they should.

Loop engineering in Claude Code and Codex - when to use a goal, loop or routine, the real commands, production patterns and two failure modes that burn money.
