## What it is

Free skill from Together AI, created by Nutlope, that guides agents such as Claude Code, Codex and Cursor to generate pages with their own visual identity from a catalog of themes.

## What it’s for

For people building new pages with agents who want to start from a defined visual theme, with quality checks, instead of the generic result.

## Benefits

- Catalog of fifty themes with reference images; proposes three that fit the prompt
- Layered rules (Floor, Reflex, Finish) and a linter, sloplint, that tests renders at several widths
- Redesigns an existing page while preserving content and links, or just audits it
- Library of 755 open photos from Wikimedia Commons, credited on the page

## Caveats

- According to the maker, the skill 'refuses to look AI-generated'.
- MIT license; no price.
- Browser checks require puppeteer-core and Chrome; Node 18 or higher.
