visual-identity skillA

visual-identity is agent-read markdown (skill) from letta-ai/skills: Build and maintain a persistent visual identity for your agent using Flux Kontext Pro. Use when the user asks the agent to generate selfies, avatars, character art, or any image that should look like the same person across generations..

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 letta-ai/skills/visual-identity@git:20260422.d32735f
Exact content
mdr add letta-ai/skills/visual-identity@sha256:6181a65e9044dfc6

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.
