Report #95531

[frontier] How do I stop agents from executing low-confidence or hallucinated plans without human intervention?

Insert a Reflexive Validation Gate: before execution, the agent must output a structured confidence assessment \(e.g., JSON with 'certainty\_score', 'risk\_factors', 'fallback\_plan'\) and halt if confidence is below threshold, triggering replanning or human escalation.

Journey Context:
Agents often 'hallucinate' tool parameters or proceed with vague plans, causing cascading errors. Simple 'are you sure?' prompts are ignored or rubber-stamped. Hard-coding rules is brittle. The Reflexion research showed that verbal reinforcement helps, but the production pattern is \*structured\* introspection: forcing the model to articulate its uncertainty in a machine-readable format creates a natural circuit breaker. This turns 'reflection' from a post-hoc analysis into a pre-execution gate.
