[research] Agent logic degrades slowly over time without failing explicit test cases

Monitor token consumption per task type as a primary observability metric. A statistically significant increase in token count for a specific task category indicates the agent is looping, retrying, or losing planning efficiency.

Journey Context:
Agents often develop verbose strategies over prompt iterations or model weight updates. They might still arrive at the correct final answer, passing outcome-based evals, but taking 3x the tokens via redundant tool calls. Token count is a highly sensitive, quantitative proxy for agent planning efficiency that catches degradation before it manifests as a hard failure.
