Atelier suite — the performance & accessibility gate. The cross-cutting quality bar every Atelier build passes before it ships: animate only compositor-safe properties, hit Core Web Vitals (LCP ≤2.5s, CLS ≤0.1, INP ≤200ms), respect prefers-reduced-motion, meet WCAG 2.2 AA (contrast, focus, keyboard, target size, semantics, screen readers), give canvas/WebGL accessible fallbacks, and run the anti-slop "AI Tells" design-integrity check. Use whenever finishing or reviewing a frontend, optimizing performance / Core Web Vitals / Lighthouse, fixing jank or layout shift, doing an accessibility/a11y audit, handling reduced motion, running a pre-ship check, or checking whether a build reads as AI-generated/templated. This is the canonical home for the perf/a11y rules the other Atelier skills reference. Part of the Atelier suite.

The file

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.
