An AI agent without a stop policy is just an expensive loop

Summary

A practical note on AI agent reliability, arguing that production agents need explicit gates for evidence thresholds, retry budgets, and impact assessment rather than relying on memory alone to determine task completion.

Most agent diagrams stop at plan → act → observe. In production, the hard part is deciding when the system has enough evidence to continue, retry, stop, or hand control back to a person. Three gates make that decision concrete: • Evidence threshold — what proves the task is actually complete? • Retry budget — how much failure is allowed before stopping? • Impact gate — can the next action be safely reversed? Memory can preserve context, but it shouldn't be treated as proof that a task succeeded. Which failure mode shows up most in real agent systems: endless retries, confident completion without evidence, or escalating too often?

The author argues that AI agents are essentially API calls with loops, emphasizing that production success depends on defensive engineering like retries, timeouts, and human approval rather than model choice.
