Report #52123

[synthesis] Agent reports task success because a sub-tool returned a 200 OK, even though the overall goal failed

Decouple tool execution success from task completion success; require the agent to verify the state change caused by the tool, not just the tool's return code.

Journey Context:
Agents often wrap APIs that return 200 OK but don't actually do what was intended \(e.g., an API that accepts a payload but silently drops a field, or a deployment that succeeds but the health check isn't live\). The agent sees Success: 200 and tells the user it's done. The synthesis of multiple postmortems shows this happens because agents are trained on API specs where 200=Good. You must force the agent to run a read operation to verify the write operation actually worked.
