Silent Failure Surface

The Silent Failure Surface is the set of AI behaviors that pass every automated check yet still damage the client relationship: a voice agent that interrupts callers, a support bot that loops a user through three retries, a research agent that returns confident but stale answers. Standard evals score outputs against expected answers, so they miss friction that only appears in live sessions. Agencies that map this surface before launch can price a monitoring retainer against it; agencies that skip it discover failures when the client forwards a complaint. Cekura simulates thousands of personas to expose interruption and gibberish patterns before go-live, while Agnost AI ingests real conversations and flags repeated retries and broken workflows as actionable intents. Both approaches treat production traffic as the primary test set, not a post-launch afterthought. The surface shrinks only when someone owns the loop between detection and a shipped fix.
