Generate a branded 1200x630 Open Graph / social share image (PNG) from an SVG template using sharp — no design tool needed. Produces the card that shows when a link is shared on LinkedIn, X/Twitter, Slack, Discord, iMessage. Use when a site has a blank/missing/ugly link preview, needs a proper og:image, or the user wants a generated social card matching their brand. Pairs with the seo-kit skill (which wires the og:image/twitter:image meta tags).

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file

We split this skill into the rules it gives an agent

2 rules. 0 are common, 1 is distinctive, and 1 is very specific to this project.

0
Common
Most of the 4 edited versions we read keep these.
1
Distinctive
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.

Common
Distinctive
Very specific

Very specific:
Run node scripts/gen-og.mjs → writes public/og-image.png.
line 29
Distinctive:
Verify the card at https://www.opengraph.xyz.
line 47

“Common” is measured: kept by at least 6 in 10 of the 4 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

OG Image Generator

Generates a proper 1200×630 PNG social-share card from an SVG template, rasterized with sharp. No Figma/Photoshop needed, fully reproducible, and regenerable whenever the text changes.

Why

Social crawlers need a real raster image at an absolute URL for rich previews. A relative path or a square favicon gives blank/tiny previews. This builds a real branded 1200×630 card.

What it produces

scripts/gen-og.mjs — edits the config at the top (name, role, subline, footer), runs node scripts/gen-og.mjs, and writes public/og-image.png (1200×630).
A dark "IDE/terminal" themed card by default (window dots, gradient name, mono subtext) — restyle the SVG freely.

How to use it

Copy references/gen-og.mjs into the project's scripts/.
npm i -D sharp.
Edit the CONFIG constants at the top (name, role, subline, footer text, colors).
Run node scripts/gen-og.mjs → writes public/og-image.png. Add an npm script "gen:og": "node scripts/gen-og.mjs" for convenience.

Wire the meta tags (or use the seo-kit skill) with an absolute URL:

<meta property="og:image" content="https://DOMAIN/og-image.png" />
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:image" content="https://DOMAIN/og-image.png" />

Notes

Fonts: SVG text renders with fonts installed on the build machine. The template uses Consolas, monospace and Segoe UI, Arial, sans-serif (safe on Windows/most CI). For a custom font, install it on the build env or embed it as base64 in the SVG.
Absolute URL is mandatory for OG/Twitter images, and LinkedIn caches hard — re-scrape via the Post Inspector after deploying.
