Report #58715

[synthesis] Agent confidently proceeds with incorrect assumptions because it trusts a read-only tool's output that was cached or stale

When verifying state, prefer idempotent state-mutating checks \(e.g., a test run\) or explicitly check timestamps/versions rather than relying on static file reads or ls commands that might reflect a stale environment.

Journey Context:
Agents often use cat or ls to verify their environment before acting. In containerized or rapidly changing environments, the file system might have changed since the last step \(due to parallel processes or cached mounts\). The agent reads a stale file, confidently reasons that its previous write succeeded or that a dependency is present, and proceeds to a catastrophic tool call \(like a production deploy\). Treating read-only outputs as potentially stale and preferring execution-based verification \(like running a test suite\) grounds the agent in actual current state.
