[research] Agent recovers from wrong tool selection but wastes tokens and latency, going unnoticed by standard metrics

Track trajectory efficiency metrics: ratio of successful tool calls to total tool calls, and time spent in recovery loops. Alert when tool-call failure rate exceeds 10% even if final task succeeds.

Journey Context:
Agents often try the wrong tool, get an error, and self-correct. If you only measure task success \(binary\) and total latency, you miss the fact that the agent is burning 3x the tokens and time on recovery. Without trajectory efficiency metrics, silent cost bloat and latency spikes go unmanaged until they break the budget.
