phone-calls skillA

phone-calls is agent-read markdown (skill) from vellum-ai/vellum-assistant: Make outgoing phone calls, receive incoming calls, and pull up past call transcripts.

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

Latest version
mdr add vellum-ai/vellum-assistant/phone-calls@git:20260826.91d6236
Exact content
mdr add vellum-ai/vellum-assistant/phone-calls@sha256:cdfe66613ff51eda

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.
