Report #82565

[synthesis] Agent hallucinates based on stale tool outputs that no longer reflect reality

Implement a TTL \(Time-To-Live\) or version hash on tool outputs in the agent's memory, forcing a re-fetch of the state if the tool output is older than a threshold or if a mutating tool was called in the interim.

Journey Context:
Agents often read a file or API state, execute a few intermediate steps, and then make a decision based on the initially read state, assuming it hasn't changed. In dynamic environments \(or if the agent itself changed it in a different branch\), this leads to conflicts. Developers assume the agent's linear context window guarantees temporal consistency, but if the agent backtracks or loops, the 'read' output is stale. Treating tool outputs as cached data with a TTL, rather than eternal truths, prevents the agent from reasoning over outdated reality.
