voice-preflight skillA

voice-preflight is agent-read markdown (skill) from calle-ai/awesome-phone-call-agents: Hear a CALL-E phone call task spoken by your own text-to-speech provider before a real person does, then refuse a script whose critical line would not survive being spoken..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
