Report #25321
[synthesis] Agent reports success but file write went to wrong path \(silent no-op\)
Always include a verification step after a write/edit tool call. The agent must read the target file and check for the expected change, or run a syntax check/linter, before reporting success.
Journey Context:
File write tools often return a generic success string. If an agent constructs a path incorrectly \(e.g., ./src/app.js vs ./src/App.js on a case-insensitive OS\), the tool succeeds, but the application doesn't change. The agent sees the success string, assumes the state is updated, and terminates. Verification loops cost an extra tool call but catch silent no-ops.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
