Painted Cover Series: example output

6 images made by this skill from examples/signal and examples/lowtide

What you get

  • Two built-in art directions, gouache and linocut, or your own
  • Up to 40 posts per series, the first picture anchoring the style of the rest
  • Titles set as real type where the art is calm, in a palette color that passes contrast
  • Covers at 1200×630, 1600×900, 1080×1080 and 1080×1350, plus og and twitter meta tags
  • Checks for busy art behind the title, low contrast and titles that don’t fit
  • Open-source licenses for every part it builds on

Good fit

  • Newsletter writers can give every issue a painted header in the same style, with the title set in a real typeface.
  • Engineering and product blogs can make link previews at 1200×630 that look illustrated rather than templated.
  • Content teams can add new posts to series.json later, and only the new pictures are made.

Not for

  • Pictures with words, charts or screenshots in them
  • Photographic covers or stock photos
  • One-off covers in a different style per post

About this skill

Illustrated covers for every post of a blog or newsletter in one painted style: mid-century gouache, two-color linocut or your own art direction. An image model paints one picture per post, the first anchoring the style for the rest. The script then sets each title as real type in the calm part of the picture, with a color that passes contrast, in link-preview, wide, square and portrait sizes.

Example request

Make linocut covers for our engineering blog’s last four posts, as link previews and square images.

FAQ

Does the image model write the title?

No. Image models still misspell words, so the pictures have no text. The script reads each picture, finds the calm side, and sets the title there in a real typeface with a color that passes contrast.

Which styles are there?

Two are built in: mid-century gouache with a Fraunces title and two-color linocut with a Bitter title. You can also write your own art direction, with a palette, and pick your own Google font.

Which sizes does it make?

Any of 1200×630 for link previews, 1600×900, 1080×1080 and 1080×1350, and it writes the og and twitter meta tags for the 1200×630 covers.

Which agents is Painted Cover Series written for?

Any agent that reads SKILL.md folders, including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode.

Do I own what I make with it?

Yes. Everything your agent makes with this skill is yours, including for client and commercial work.

What if it doesn’t work for me?

Email support@lookbk.dev within 7 days of buying and we’ll fix it or refund you.
