Designs and renders a custom GitHub social preview (the 1280x640 card shown when a repository link is shared on X, Slack, LinkedIn, Reddit, Hacker News, or Discord) from the repository's own brand: logo, colors, fonts, tagline, install command, and open-source facts discovered in the repo and its website. Renders deterministically with the social-preview CLI, checks it at feed size, and hands over the web-only upload plus a gh check that it took. Use when a repo shows GitHub's generic card…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Overview A repository link shared anywhere unfurls into a card. Without a custom image GitHub generates one from the owner avatar, name, and description, which only works for brands people already know. A project still earning its audience needs the card to say what it is. This skill reads the brand from the repository, writes the card's copy, renders it with the `social-preview` command, checks it at the size people see it, and hands over the upload. ## Mental model - The card is read in under a second at 400–600 px wide in a feed. It carries a name, one claim, and at most two supporting lines. Everything else is noise at that size. - The repo already has a brand. Find it and reuse it; never invent colors, a logo, or a tagline the project doesn't use. - It is an open-source card. It says what the project is and how to get it, not what it costs or how popular it is today. …

How to install
mdr add muvon/octomind-tap/repo-social-preview@sha256:f59ae382d2bc2226The line at the top of this page pins the label git:20261031.7d8e869, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
