What it does

In the author's own words, from each skill's SKILL.md.

  • article-thumbnail

    Generate a brand-consistent still thumbnail (cover image) for a blog or Substack article. For Claude Code only. Activate when the user asks for a thumbnail, cover image, hero image, or social preview for a written article. Reads the article, designs a scene that visually argues the article's main idea, then runs a small bundled Node script (generate.js) that calls Google's Gemini image API.

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
