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
# GitHub Social Preview Skill ## Intent Generate branded GitHub social preview images using repo metadata, visual rules, and the included preview generator. ## Do Not Use When - Do not use for unrelated image generation, manual graphic design requests, or previews without enough repo identity context. - Required context is missing and cannot be reasonably inferred. - A more specific skill in this repo is a better match. ## Constraints - Do not fabricate missing facts, measurements, dates, sources, or user context. - Keep output aligned with Mick's direct, practical communication style unless the skill says otherwise. - Preserve safety, legal, medical, financial, and operational boundaries stated in this file. - Prefer concise, usable output over broad explanation. ## Validation Checklist - [ ] The output matches the skill's intended task and platform. - [ ] Required inputs, assumptions, and uncertainty are explicit. - [ ] Safety, scope, and source limits are respected. - [ ] The response follows the requested format or the skill's default output format. - [ ] The result is practical enough to use without another cleanup pass. …

How to install
mdr add mickpletcher/ai-skills/github-social-preview@sha256:e14fddb2789de787The line at the top of this page pins the label v1.2.0, 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.
