## AI overview

This article argues that AI agents can return HTTP 200 responses while still failing business tasks. It proposes tracking apology responses as a reliability signal to expose context starvation caused by stalled dependencies, timeouts, stale synchronization, dropped data, or payload truncation in retrieval and orchestration pipelines.

## Source excerpt

An AI agent that returns "I apologize, but I cannot find that order" ships an HTTP 200. Infrastructure dashboards call that healthy; the business calls it a failure. Tracking apology phrases as a first-class SLO surfaces context starvation, a stalled dependency, a timeout guard tripping, or silent payload truncation, none of which HTTP status codes and CPU graphs can see.
