guardian-verify-setup skillA

guardian-verify-setup is agent-read markdown (skill) from vellum-ai/vellum-assistant: Set up channel verification for phone, Telegram, Slack, Discord, or email channels via outbound verification flow.

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/guardian-verify-setup@git:20260901.86fbbc2
Exact content
mdr add vellum-ai/vellum-assistant/guardian-verify-setup@sha256:b7fbbb3c137f2fd3

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.
