Report #75537

[research] Agent success rate remains flat but cost and latency double over a month

Track and alert on the ratio of successful steps to total steps \(step efficiency\) and tokens per task, not just final task success rate.

Journey Context:
An agent might still reach the correct final answer, but if a downstream API changes slightly, the agent might take 5 retries instead of 1. Final-outcome evals show 100% success, masking a massive degradation in efficiency and cost. Observability must track the path \(steps, tokens, retries\) not just the destination.
