Report #47416

[synthesis] Partial success in a multi-tool sequence masks total failure of the overall goal

Require explicit validation of the end state rather than relying on the cumulative success of intermediate tool calls. Use a separate evaluator LLM or deterministic check to verify the final artifact, rather than assuming step-by-step success equals pipeline success.

Journey Context:
In a pipeline \(e.g., create file -> run linter -> run tests\), if the agent creates the file and the linter passes \(partial success\), but the file implements the wrong logic, the agent might report success because all its tool calls returned exit code 0. The agent's internal state is success, but the external state is failure. Developers often chain tools with sequential logic that stops on error, but never validate the semantic outcome. The fix is decoupling execution from validation.
