Extract the full design language from any website URL. Produces 8 output files including AI-optimized markdown, visual HTML preview, Tailwind config, React theme, shadcn/ui theme, Figma variables, W3C design tokens, and CSS variables.

We split this skill into the rules it gives an agent

5 rules. 0 are common, 1 is distinctive, and 4 are very specific to this project.

  • 0

    Common

    Most of the 6 edited versions we read keep these.

  • 1

    Distinctive

    This author's own choices. Worth a look.

  • 4

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Ensure designlang is available.

    line 13
  2. Very specific:

    Import *-variables.css into their stylesheet

    line 52
  3. Very specific:

    Import *-theme.js for React/CSS-in-JS projects

    line 54
  4. Very specific:

    Import *-figma-variables.json into Figma for designer handoff

    line 55
  5. Distinctive:

    Use the markdown file as context for AI-assisted development

    line 57

“Common” is measured: kept by at least 6 in 10 of the 6 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Extract Design Language

Extract the complete design language from any website URL. Generates 8 output files covering colors, typography, spacing, shadows, components, breakpoints, animations, and accessibility.

Prerequisites

Ensure designlang is available. Install if needed:

npm install -g designlang

Or use npx (no install required):

npx designlang <url>

Process

  1. Run the extraction on the provided URL:
npx designlang <url> --screenshots

For multi-page crawling: npx designlang <url> --depth 3 --screenshots For dark mode: npx designlang <url> --dark --screenshots

  1. Read the generated markdown file to understand the design:
cat design-extract-output/*-design-language.md
  1. Present key findings to the user:
    • Primary color palette with hex codes
    • Font families in use
    • Spacing system (base unit if detected)
    • WCAG accessibility score
    • Component patterns found
    • Notable design decisions (shadows, radii, etc.)
  2. Offer next steps:
    • Copy *-tailwind.config.js into their project
    • Import *-variables.css into their stylesheet
    • Paste *-shadcn-theme.css into globals.css for shadcn/ui users
    • Import *-theme.js for React/CSS-in-JS projects
    • Import *-figma-variables.json into Figma for designer handoff
    • Open *-preview.html in a browser for a visual overview
    • Use the markdown file as context for AI-assisted development

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
