Report #38533

[synthesis] File system success responses mask data corruption, leading downstream agents to execute destructive operations based on invalid reads

Require round-trip validation \(write-then-read-then-parse\) for all critical state-mutating tool outputs before allowing destructive follow-up actions.

Journey Context:
Agents trust tool return codes. A 200 OK or 0 exit code from a write operation only means the OS accepted the bytes, not that the bytes are logically valid. If Agent B reads a corrupted file and the parser returns a default empty object, Agent B assumes the file is legitimately empty and proceeds \(e.g., deleting the source\). A write-then-read loop forces the agent to verify its own output, bridging the gap between OS-level success and application-level validity, trading execution speed for data integrity.
