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
- Download the package
- Print the checklist (or bookmark it)
- Run checklist before deploy (catches 80% of loop issues)
- Integrate decision tree into your agent's error handling
- 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:
Agent tries task -> fails -> retries -> fails again -> retries -> ... (100+ attempts)
Cost: $50, API quota burned, user frustrated
With guardrails:
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
Decision logic reference
| Error Type | Example | Action | Max Retries |
|---|---|---|---|
| Transient | 429, timeout, connection reset | RETRY | 2-3 |
| Auth | 401, 403, bad signature | STOP | 0 |
| Validation | Invalid input, schema mismatch | STOP | 0 |
| Policy | Forbidden action, safety check | STOP | 0 |
| Unknown | Unhandled exception, weird error | ESCALATE | 0 |
| Repeated | Same error 3+ times | ESCALATE | 0 |
