web-motion-auditor is a skill for Claude Code, Codex from frankxai/awesome-motion-design-agent-skills. It costs 52 tokens per session (222 once invoked), scanned A, original, CC0-1.0.

A review guide for animation in websites and apps built with HTML, React, or Next.js. It examines loading, hover, focus, clicks, page changes, scrolling, and other interactive states.

In plain words
What is it for?
Use it to audit animation on desktop and mobile, check reduced-motion support and focus visibility, capture evidence, and receive fixes tied to files.
Why use it?
It finds motion that is hard to read, blocks interaction, performs poorly, or ignores accessibility settings. It turns those findings into specific code changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

web-motion-auditor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Web Motion Auditor

Workflow

  1. Run or open the app.
  2. Inspect the animated states: load, hover, focus, click, route transition, scroll, empty/loading/success/error.
  3. Check accessibility:
    • prefers-reduced-motion
    • focus visibility
    • no motion that blocks reading or interaction
  4. Check performance on desktop and mobile widths.
  5. Capture screenshots/video when possible.
  6. Score with the motion quality rubric.
  7. Return concrete fixes with file references.

Common Fixes

  • Shorten transitions.
  • Use transforms/opacity instead of layout-heavy properties.
  • Reduce stagger count.
  • Add reduced-motion branch.
  • Replace decorative motion with state-explaining motion.
  • Move complex narrative motion to Remotion or a controlled hero scene.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
