Report #79670

[architecture] Agents blindly execute high-stakes actions based on low-confidence or ambiguous outputs from upstream agents, causing irreversible damage

Require upstream agents to output a structured confidence score \(0.0-1.0\) alongside their primary payload. Define hard thresholds in the orchestrator: if confidence is below threshold, route to a human-in-the-loop \(HITL\) or a fallback agent.

Journey Context:
LLMs are prone to hallucination and overconfidence. If a 'Data Extraction Agent' extracts a transaction amount with low confidence, passing it to an 'Execution Agent' is dangerous. Developers often try to prompt the LLM to 'only act if sure', which fails. Forcing a numeric score and handling it in deterministic orchestrator code is reliable. Tradeoff: HITL introduces latency and bottlenecks, so thresholds must be tuned per use-case to avoid alert fatigue.
