motion-anti-slop

motion-anti-slop is a cursor rule for Cursor from taotao135791-bit/gsap-transform. It costs 106 tokens per session (378 once invoked), scanned A, original, MIT.

A rule set for checking GSAP animations, where GSAP is a JavaScript library for creating web motion. It looks for predictable patterns that can make animations feel generic, break accessibility, or fail silently.

In plain words
What is it for?
Use it to audit, lint, or review GSAP animations. It checks timing, easing, choreography, accessibility, performance, visual composition, and common wiring mistakes.
Why use it?
It helps catch animation problems before release, including missing reduced-motion support, poor performance, overused effects, and incorrect loading or setup.

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

motion-anti-slop 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 10d 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

motion-anti-slop

32+ deterministic block / warn rules in seven groups:

  • A. Duration tells — too short / too long defaults
  • B. Ease abuseback.out(1.7) / elastic.* / bounce.* as defaults (only one branded character moment per page)
  • C. Choreography — hover lift+scale+shadow combo, parallax on every section
  • D. Accessibility — missing prefers-reduced-motion (Pre-Flight Failure), scrub/pin under reduced-motion
  • E. Performance — animating layout properties, will-change abuse
  • F. Composition — single accent leak, AI-purple default, type pool drift
  • G. Wiring & loading silent failuresgsap.from(autoAlpha:0) on CSS-hidden element, CSS transform pre-existing, jsdelivr ESM, esm.sh named imports for plugins, MotionPath/DrawSVG on non-path

Each rule has detect signature, wrong snippet, fix snippet, severity (block / warn).

For the full A–G checklist with all detect/fix snippets: see skills/motion-anti-slop/SKILL.md.

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.
