[synthesis] Latency spikes after a deployment while error rates stay flat, hiding an upcoming quality regression
Alert on per-workflow latency percentiles \(p50, p95, p99\) immediately after every model, prompt, or tool change, and require a quality eval run correlated with the latency shift before declaring the rollout healthy.
Journey Context:
Traditional SLOs treat latency and quality as separate concerns; latency alerts are often tuned generously to avoid noise. Production agent monitoring guides and graceful-degradation research note that latency spikes are frequently the first detectable signal of a regression, appearing before quality scores drop. The synthesis is that post-deploy latency is not just a performance signal; it is often the first observable symptom of the agent taking longer to reason, retry, or disambiguate because the underlying behavior has changed.
