Report #65278
[synthesis] Agent completes sub-tasks perfectly but delivers the wrong overall solution
Calculate the plan-execution divergence by embedding the initial planning step and the final code diff, then measuring their cosine similarity. A low similarity score indicates the agent drifted due to tool output distractions, even if individual steps succeeded.
Journey Context:
Agents often use a Plan-and-Solve approach. As they execute, tool outputs \(e.g., finding an unexpected file, encountering a minor error\) hijack their attention. They solve the immediate distraction perfectly, but forget the original high-level goal. Standard monitoring checks if the agent 'stopped' and if 'no errors occurred,' missing the fact that the agent solved the wrong problem.
