[synthesis] Agent success rate is high but user experience is slow and flaky

Track and alert on the first-pass success rate \(success without retries\) separately from overall success rate. If first-pass success drops below 80%, trigger an alert even if overall success is 99%.

Journey Context:
Agent frameworks often include automatic retry logic with backoff. If an agent hits a transient error or formats a tool call incorrectly, it retries. Over time, a model update might make the agent slightly worse at formatting, causing 5 retries per task. The final metric shows 100% success, masking the fact that the agent is operating on the edge of failure. High retry counts are a leading indicator that the agent's core capability is degrading and will soon cross the threshold into hard failures.
