Report #82756
[synthesis] Agent executes tasks successfully but plan-execution alignment degrades
Compute a semantic similarity score between the agent's stated step \(Chain of Thought\) and the actual tool invoked. Alert when similarity drops below baseline, even if task outcome succeeds.
Journey Context:
Agents often generate a plan \(CoT\) then execute tools. In production, models sometimes 'forget' their plan and execute a different but functionally equivalent path, or succeed by accident. Teams only monitor task success. However, decoupled plan-execution is a massive leading indicator of fragility. When the environment changes slightly, the accidental success path breaks, causing sudden 0% success rates. Tracking CoT-to-tool alignment catches this silent rot.
