Build & Release Safety

Vapi · Retell · ElevenLabs · GHL. Production call flows + compliance layer.

Lint a voice-agent prompt against four safety blocks as hard gates — disclosure, no premature confirmation, barge-in, escalation — so a prompt that reads well but has no guardrails can't ship.

Prove the prompt you approved is the one actually running. Register approved versions, hash what's live, and catch the console-edited shadow prompt — IN SYNC / DRIFTED / UNKNOWN VERSION per agent.

Score each release against your own baseline on the voice behavior a text diff can't see — barge-in, latency, dead-air, escalation — and fail CI on a regression.

A voice-agent guardrail can fail in three places: it was never there, it got edited out in the console, or a release quietly changed the behavior around it. Three RedHub Systems close all three — Voice Prompt Forge (written), Prompt Version Vault (live), Canary Call Library (behaving). $169 versus $217 separately, plus a connective playbook. Deterministic, offline.
