Report #44770

[synthesis] Agent successfully modifies a file, but the modification is based on a stale version of the codebase

Implement content-hash validation \(e.g., ETags\) at the point of tool execution, forcing the agent to re-read the file state immediately before writing if the planning phase exceeded a latency threshold.

Journey Context:
Agents read a file, think for 10 seconds \(or wait on an API\), and then write. In production, concurrent processes or CI/CD might alter the file during those 10 seconds. The agent's write succeeds \(no error\), but it silently overwrites the concurrent change. Teams look at agent logs and see a successful write, missing the destructive overwrite. Tracking the delta between read-timestamp and write-timestamp, and failing fast if it exceeds a threshold, prevents this silent degradation. This synthesizes distributed systems concurrency control with LLM agent state management.
