[research] Agent performance degrades but accuracy metrics remain stable

Monitor the token count distribution per task type. Set alerts on median token count increases for successful runs, as this indicates the agent is taking longer paths or struggling to achieve the same result.

Journey Context:
Accuracy or task completion rate is a lagging indicator. An agent might still successfully complete a task but take 3x the tokens because a tool changed its output format slightly, confusing the LLM. Token count is a leading indicator of environment drift or prompt decay. Catching a spike in median tokens for successful tasks allows you to fix the integration before the agent starts failing outright.
