What you get

2 production-ready files:

loop-guardrails-checklist.md: Pre-deployment checklist

  • Max iterations limit (how many loops before forced stop?)
  • Timeout budgets (how long should one agent action take?)
  • Escalation triggers (when to ask for human help)
  • Runtime enforcement (code that actually stops loops)
  • Testing patterns (how to safely verify guardrails work)

📋 stop-retry-escalate-decision-tree.md: Operational framework

  • STOP criteria: non-retryable errors (auth, validation, policy violations)
  • RETRY criteria: transient failures (429, timeouts, connection errors)
  • ESCALATE criteria: unclear errors, confidence drop, manual review needed
  • Real error examples with decision logic
  • Integration hints for your agent framework

How to use

  1. Download the package
  2. Print the checklist (or bookmark it)
  3. Run checklist before deploy (catches 80% of loop issues)
  4. Integrate decision tree into your agent's error handling
  5. Set runtime constraints (max iterations, timeouts, escalation)

What this prevents

✓ Infinite loops from retry storms
✓ Cascading failures (one error triggering chain reaction)
✓ Unbounded cost (preventing 1000-call death spirals)
✓ Silent failures (agent looping without visibility)
✓ "Better prompt" syndrome (guards in code, not AI)

Real-world example

Without guardrails:

code
Agent tries task -> fails -> retries -> fails again -> retries -> ... (100+ attempts)
Cost: $50, API quota burned, user frustrated

With guardrails:

code
Agent tries task -> fails -> retries once -> fails -> 
Check: Is this retryable? No -> STOP and escalate to human
Cost: $0.05, human reviews in 2 minutes, clear path forward

When you need this

  • Building production AI agents (not experimental chatbots)
  • You've had agents loop forever in production
  • Your team needs clear decision logic for error handling
  • You want guardrails in code, not just prompt tweaks
  • You need to hand off agent operations to on-call engineers
