Report #36343
[frontier] How to prevent agents from proceeding with invalid outputs without expensive human-in-the-loop?
Deploy a 'critic' agent with formal constraints \(Pydantic/JSON Schema\) that validates outputs against contracts BEFORE execution; violations trigger automatic retry with corrective feedback.
Journey Context:
Post-hoc eval is too late; guardrails only check syntax. A 'constitutional' critic \(separate LLM with frozen system prompt\) checks semantic constraints \(e.g., 'never expose PII'\) at inference time. Tradeoff: latency/cost vs. safety. This emerges from DSPy's assertions and InstructGPT-style RLHF applied at runtime, not training time.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
