Report #38956
[architecture] Agent hallucinates the output of a tool call without actually executing it, passing fake data to the next agent
Decouple tool execution from agent reasoning. The orchestrator must intercept tool calls, execute them in a sandbox, and inject the actual result back into the agent's context before proceeding.
Journey Context:
Open-source or weaker models sometimes fail to emit proper tool-call syntax or just guess the result of a function call \(e.g., returning a fake URL\). If the orchestrator blindly trusts the agent's output stream, fake data propagates downstream. Forcing execution at the orchestration layer guarantees real data. Tradeoff: Requires strict orchestration control vs. allowing agents to self-reflect on imagined tool outputs.
