    design-tokens

    Expert in design tokens using the DTCG specification. Use this skill when users ask about design tokens, DTCG format, token validation, formatting, transformation, color spaces (sRGB, Display P3, OKLCH), references and aliasing, resolvers, theming with modifiers/contexts, multi-platform design systems, accessibility, or working with tools like jq, jsonata, and terrazzo. Helps with token file creation, resolver configuration, structure, naming conventions, and best practices.

    dependency-audit

    Audit project dependencies for security vulnerabilities, licensing issues, maintenance health, and optimization opportunities. Use it during regular security audits (monthly or quarterly); before a major release when you want to ensure the dependency tree is clean; when evaluating whether to adopt or replace a dependency; after a security advisory affects one of your dependencies; when your install times or bundle sizes have grown noticeably.

The file

We split this skill into the rules it gives an agent

3 rules. 0 are common, 1 is distinctive, and 2 are very specific to this project.

  • 0

    Common

    Most of the 27 edited versions we read keep these.

  • 1

    Distinctive

    This author's own choices. Worth a look.

  • 2

    Very specific

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

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

    Run static analysis -- grep JSX/TSX/HTML files for violations

    line 11
  2. Distinctive:

    If dev server is running, optionally run axe-core CLI:

    line 12
  3. Very specific:

    Use file:line references. Include the fix for each finding.

    line 25

“Common” is measured: kept by at least 6 in 10 of the 27 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.

Accessibility Audit

Workflow

  1. Detect framework from package.json (React, Vue, Svelte)
  2. Run static analysis -- grep JSX/TSX/HTML files for violations
  3. If dev server is running, optionally run axe-core CLI:
    npx @axe-core/cli@4 http://localhost:3000
  4. Report findings grouped by severity

Output format

Group by WCAG criterion:

  • Critical (A) -- blocks assistive technology users
  • Serious (AA) -- significantly impacts usability
  • Suggestions -- best practice improvements

Use file:line references. Include the fix for each finding. Prioritize keyboard navigation and screen reader issues; never auto-fix -- show what to change and why.

Error Handling

  • Framework undetected -- scan all .html, .jsx, .tsx, .vue files

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.
