Report #66136

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

Decouple tool execution success from task completion validation by requiring a separate, independent verification step \(e.g., a read-back or test execution\) that does not rely on the tool's return code.

Journey Context:
When an agent writes a file or makes an API call and gets a success status, the LLM assumes the intent was fulfilled. For example, writing a configuration file that is syntactically valid but semantically wrong. The tool says Success, so the agent stops. Developers rely on exit codes. The synthesis is that agents need an independent verification tool call whose sole job is to check the state, breaking the assumption that write success equals intent fulfillment.
