Report #81663
[architecture] Downstream agents trust upstream agent assertions without verifying the actual state of the external system, leading to hallucinated dependencies
Implement a 'trust but verify' pattern where the receiving agent uses read-only tools to verify critical inputs before acting. Do not pass resolved 'facts' between agents; pass 'queries' or 'pointers' to data.
Journey Context:
Agent A \(planner\) tells Agent B \(coder\) 'The API uses REST and returns JSON.' Agent B writes code assuming this, but Agent A hallucinated the API format. If Agent B blindly trusts the context, the code fails. Passing pointers \(e.g., 'Check the OpenAPI spec at URL X'\) instead of resolved facts forces Agent B to fetch and verify the truth itself. The tradeoff is increased tool calls and latency, but it drastically reduces cascading hallucination errors by grounding each agent independently.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
