Render 1200x630 Open Graph and Twitter card PNGs, one per page, from .atelier/brand.json colors, fonts, logo and studio name; single card from flags or a batch from a pages.json manifest. Use when adding og:image or twitter:image meta tags, setting up social link previews for a site or blog, or regenerating cards after a brand color or font change.
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
## Run
Run from the project root that holds `.atelier/brand.json` (or pass `--project <dir>`):
```bash
node "${CLAUDE_PLUGIN_ROOT}/bin/atelier" og pages.json public/og
node "${CLAUDE_PLUGIN_ROOT}/bin/atelier" og --title "TideWane" --subtitle "A deep-sea idle dungeon crawler" --slug home --out public/og
```
`pages.json` is `{ "pages": [ { "slug": "home", "title": "...", "subtitle": "..." } ] }` or a bare array of pages.
JS API (the module path goes in as an argument and is loaded through `pathToFileURL`, so the import also works with Windows paths; importing it does not start the CLI):
```bash
node --input-type=module -e "const { pathToFileURL } = await import('node:url'); const m = await import(pathToFileURL(process.argv[1]).href);
const { loadBrand } = await import(new URL('../brand-memory/index.mjs', pathToFileURL(process.argv[1])).href);
const paths = await m.generateCards({
brand: loadBrand(process.cwd()),
pages: [{ slug: 'home', title: 'TideWane', subtitle: 'A deep-sea idle dungeon crawler' }],
outDir: 'public/og',
});
for (const p of paths) console.log(p);" "${CLAUDE_SKILL_DIR}/index.mjs"
```

How to install
mdr add ethany33/atelier/og-card-generator@sha256:c8857838a2602764The line at the top of this page pins the label git:20260924.e19099e, 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.
