og-image skillA

og-image is agent-read markdown (skill) from beckyisj/webdev-kit: Generate an OG image (1200x630) for any website or tool. Designs for small-preview readability (WhatsApp, Slack, iMessage). Use when creating or updating social preview images..

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.

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.
