vellum-avatar skillA

vellum-avatar is agent-read markdown (skill) from vellum-ai/vellum-assistant: Customize the assistant's avatar - build a native character, upload an image, or generate one with AI.

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-avatar@git:20260603.ff934d9
Exact content
mdr add vellum-ai/vellum-assistant/vellum-avatar@sha256:6c1928d28c84558f

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.
