Og Card Maker

Generate a 1200×630 social/OG card in a locked house style from a post or release line, plus honest alt text written by a vision model that looked at the final render. Use when a blog post, release, or project page needs a link-preview image that matches the content.

OG card maker

Runs the bundled nanoodle workflow workflows/og-card.noodle-graph.json against the NanoGPT API in four stages: the content (Post) and a locked art direction (Style) are joined into a briefing; an LLM art-director writes one disciplined image prompt composed for a wide landscape crop (for releases, the literal version string must appear as rendered text); an image model (nano-banana-2-lite) paints the card — check the AltText output to confirm any literal text rendered correctly; then the image fans out to a local resize (Hero, exactly 1200×630 — the OG spec) and a vision model that writes alt text (AltText) from the actual pixels — if the render botched something, the alt text says what is really there. Requires Node.js >= 20 and the nanoodle npm package (npx nanoodle fetches it).

API key

The run needs a NanoGPT API key. Use whichever is available:

NANOGPT_API_KEY already set in the environment — prefer this; no extra flags.
A .env file containing NANOGPT_API_KEY=... — pass --env-file <path> only when the key is not already in the environment. (With this CLI, --env-file overrides ambient NANOGPT_API_KEY.)

Never print the key.

Run

From this skill's directory (or prefix paths if running from elsewhere). Pass the post body (or a vX.Y.Z — changelog line for releases) as Post:

npx nanoodle run workflows/og-card.noodle-graph.json \
  --input "Post=v2.3.0 — parallel graph execution lands, twice as fast on wide graphs" \
  --out ./og-out

A whole post attaches as a file (.md/.txt are read as text): --input "Post=@content/posts/my-post.md". Lock in your own look by overriding Style once and keeping it verbatim across runs — consistency is what makes the cards yours.

Inspect the interface anytime with:

npx nanoodle inspect workflows/og-card.noodle-graph.json

Inputs

Key	Required	What to pass
`Post`	yes	Post body, or `vX.Y.Z — <changelog line>` for a release
`Style`	no (default baked in)	House art direction: palette, composition rules, what to avoid
`System prompt`	no	Override the art-director LLM's instructions

Outputs

Hero is the card: saved under --out as Hero.<ext>, already resized/cropped to 1200×630. Use the path the CLI prints on the Hero: line — do not hard-code .png.
AltText is a text output: printed on the AltText: stderr line and included in the stdout JSON as outputs.AltText — one factual sentence, ready for the post's front matter or og:image:alt.

Serve as an MCP tool

The same graph file works unchanged as a typed MCP tool for interactive one-offs ("regenerate the card for the caching post, moodier"):

mkdir -p ~/noodles && cp workflows/og-card.noodle-graph.json ~/noodles/og-card.json
claude mcp add nanoodle -- npx nanoodle-mcp --graphs ~/noodles --out ~/noodle-out

Cost

Each run costs about $0.05 in NanoGPT credit (the image generation is ~$0.04; the LLM and vision steps are a cent or less combined). The resize is local and free. Runs spend real credit — tell the user before regenerating repeatedly.
