Generate an OG image (1200x630) for any website or tool. Designs for small-preview readability (WhatsApp, Slack, iMessage). Use when creating or updating social preview images.
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
# OG Image Generator Generate a branded OG/social preview image for any website or tool. **Argument**: `$ARGUMENTS` is the tool/site name (e.g., "Podcast Packager", "PRISM"). ## Design Principles **OG images appear tiny** — WhatsApp, Slack, iMessage, and Twitter show them as small thumbnails. Design for readability at thumbnail size: - **Fill the frame**: Use minimal padding. Content should occupy 70-80% of the canvas, not float in whitespace. - **Bold contrast**: Text must be clearly readable against the background at small sizes. - **Few elements**: Logo + title + one subtitle + domain. No small pills or fine details that disappear at thumbnail size. - **Test mentally**: Imagine the image at 300x157px — can you still read the title? ## Steps ### 1. Check for existing brand assets Look for existing logos, color schemes, or SVGs in the project to match the brand. If the project has an existing `og-image.svg` from a sibling tool, use it as the master template so the family stays consistent. ### 2. Create the SVG Create a new SVG at the target project's `public/og-image.svg` (or project root if no `public/` dir). **Canvas & crop zone:** …

How to install
mdr add beckyisj/webdev-kit/og-image@sha256:0dd848464019377fThe line at the top of this page pins the label git:20260906.5003aa5, 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.
