vellum-client-capabilities skillA

vellum-client-capabilities is agent-read markdown (skill) from vellum-ai/vellum-assistant: Truthful answers about what the Vellum client apps can and cannot do on the user's device. Device location and GPS are unavailable in every client and there is no location permission prompt to approve, so location requests are answered by asking for a typed city or address instead..

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/vellum-client-capabilities@git:20260908.eb6410e
Exact content
mdr add vellum-ai/vellum-assistant/vellum-client-capabilities@sha256:de895e39d56d0ff8

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.
