renfei-designSkilla11y-audit
Audit Figma designs for WCAG accessibility issues — color contrast, minimum font size, touch target sizing, and missing text alternatives. Use when asked to check accessibility, audit contrast ratios, find a11y issues, verify WCAG compliance, or review designs for accessibility problems. Scans nodes, analyzes offline, and annotates issues in Figma.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
2 rules. 0 are common, 2 are distinctive, and 0 are very specific to this project.
0
Common
Most of the 10 edited versions we read keep these.
2
Distinctive
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 8
When asked to audit performance, evaluate the application across these three critical domains:
- Distinctive: line 21
Do asynchronous actions have immediate optimistic UI updates?
“Common” is measured: kept by at least 6 in 10 of the 10 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.
Files
Performance Audit Protocol
When asked to audit performance, evaluate the application across these three critical domains:
1. Bundle & Network Optimization
- Are heavy libraries (charts, 3D rendering, PDF generators) being lazy-loaded using dynamic imports (e.g.,
React.lazy)? - Is the app downloading massive uncompressed images?
- Are API responses paginated or capped, rather than returning thousands of records at once?
2. Render Performance
- Is there unnecessary state residing at the top level of the component tree, causing the entire app to re-render on every keystroke?
- Are expensive calculations wrapped in
useMemo? - Are functions passed to child components wrapped in
useCallback(when appropriate)?
3. Perceived Performance
- Do asynchronous actions have immediate optimistic UI updates?
- Are there skeleton loaders preventing layout shift (Cumulative Layout Shift) while data fetches?
Output
Provide a diagnosis and the exact code refactors needed to eliminate the bottlenecks.
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.

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.
