One prompt line broke an unrelated flow: how do you gate voice agent changes?
that_dude_Zz · reddit · 2026-11-15
An engineer changed one sentence in a voice agent's prompt to fix a rude greeting; two days later human-call transfers silently stopped working for one request type, with nothing in the diff pointing to it. The team now batches prompt changes, slowing everything down. They want a suite of realistic call replays that blocks deploys when previously-passing cases fail — and note text evals feel too far from real phone calls.
