Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install github-social-preview-image

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent composes a 1280 × 640 visual that meets GitHub's requirements, from a prompt template or a reference image, using nano-banana-pro. You get a PNG ready to upload in the repository settings.
