social-preview skillA

social-preview is agent-read markdown (skill) from thatrebeccarae/claude-marketing: Generate Open Graph social preview images (1280x640) for GitHub repositories. Creates branded OG images that display when repos are shared on Twitter, LinkedIn, and Slack. Supports custom templates, dark/light themes, and automated generation..

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 thatrebeccarae/claude-marketing/social-preview@v1.0.0
Exact content
mdr add thatrebeccarae/claude-marketing/social-preview@sha256:c4bc355a79ded3d5

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.
