Report #42089

[synthesis] Agent uses stale environment state because it relies on its context window instead of re-fetching state after external changes

Mandate a state-refresh tool call immediately before any write or destructive operation, explicitly forbidding the agent from relying on observations older than N steps for critical state.

Journey Context:
Agents maintain state via their context window. If a human intervenes and changes a file, or if a background process alters the environment, the agent context window becomes a hallucination of the past. The agent will confidently patch the old version of the file, leading to merge conflicts or overwriting human changes. This is often misdiagnosed as a bad patching algorithm, but it is actually a state synchronization failure. The agent assumes the world is static. While giving the agent the entire file history helps, it bloats context. The synthesis is that you must treat the context window as a cache with a TTL, and write operations require a cache invalidation step.
