phone-retrieval skillA

phone-retrieval is agent-read markdown (skill) from calle-ai/awesome-phone-call-agents: Call one or more businesses to find out something that is only knowable by asking — stock, price, lead time, opening hours, whether a service is offered — and return one scored answer per business with the transcript as evidence. Use when the answer is not on the web because it lives behind a phone line..

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.
