How to make a page unfurl reliably in iMessage, WhatsApp, Slack, Discord, LinkedIn, and X; surface to search engines via sitemap.xml + robots.txt; and stay legible to generative engines (GEO), including the llms.txt standard for LLM corpus ingest. Use when adding or debugging OpenGraph / Twitter Card metadata, picking an OG image format, choosing where to host the image, fixing pages that "won't unfurl", auditing share previews, scaffolding /llms.txt and /llms-full.txt, or adding…
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
# OpenGraph, Share, SEO & GEO > Make the link unfurl. Make it fast. Make it match the bytes. Lossless Group convention for share metadata across all sites (Astro Knots, plugin pages, splash, fundraise decks). Optimized for **iMessage and WhatsApp first** (the channels we share through most), with Slack, Discord, LinkedIn, X, Facebook, and generative engines (Perplexity, ChatGPT, Claude, Gemini) as concentric rings around that. ## When to use this skill - Adding or auditing `<head>` meta tags on any page that gets shared - "It's not unfurling in iMessage / WhatsApp / Slack" debugging - Picking the OG image format (`.webp` vs `.jpg` vs `.png`) - Deciding where to host the OG image (`/public` vs CDN) - Building or modifying a `MetaTags`-style component - Reviewing or shipping a marketing splash, plugin page, blog post, fundraise deck - Setting up GEO (Generative Engine Optimization) on a content-heavy page - Scaffolding `/llms.txt` and `/llms-full.txt` for LLM corpus ingest, or porting that pattern to a new splash - Adding `@astrojs/sitemap` + `robots.txt` to a splash or marketing site for proper search-engine discoverability ## Hard rules (Why + How to apply) …

How to install
mdr add lossless-group/lossless-agent-skills/open-graph-share-seo-geo@sha256:a794df48f11713e6The line at the top of this page pins the label git:20260511.be5b01e, 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.
