Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00045 | $0.01184 |
| Opus 5 | $0.00023 | $0.00592 |
| Sonnet 5 | $0.00009 | $0.00237 |
| Haiku 4.5 | $0.00005 | $0.00118 |
Grade A, and why
fixing-motion-performance 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 7d 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.
This is a copy
100% identical to fixing-motion-performance — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.
fixing-motion-performance
Fix animation performance issues.
how to use
-
/fixing-motion-performanceApply these constraints to any UI animation work in this conversation. -
/fixing-motion-performance <file>Review the file against all rules below and report:- violations (quote the exact line or snippet)
- why it matters (one short sentence)
- a concrete fix (code-level suggestion)
Do not migrate animation libraries unless explicitly requested. Apply rules within the existing stack.
when to apply
Reference these guidelines when:
- adding or changing UI animations (CSS, WAAPI, Motion, rAF, GSAP)
- refactoring janky interactions or transitions
- implementing scroll-linked motion or reveal-on-scroll
- animating layout, filters, masks, gradients, or CSS variables
- reviewing components that use will-change, transforms, or measurement
rendering steps glossary
- composite: transform, opacity
- paint: color, borders, gradients, masks, images, filters
- layout: size, position, flow, grid, flex
rule categories by priority
| priority | category | impact |
|---|---|---|
| 1 | never patterns | critical |
| 2 | choose the mechanism | critical |
| 3 | measurement | high |
| 4 | scroll | high |
| 5 | paint | medium-high |
| 6 | layers | medium |
| 7 | blur and filters | medium |
| 8 | view transitions | low |
| 9 | tool boundaries | critical |
quick reference
1. never patterns (critical)
- do not interleave layout reads and writes in the same frame
- do not animate layout continuously on large or meaningful surfaces
- do not drive animation from scrollTop, scrollY, or scroll events
- no requestAnimationFrame loops without a stop condition
- do not mix multiple animation systems that each measure or mutate layout
2. choose the mechanism (critical)
- default to transform and opacity for motion
- use JS-driven animation only when interaction requires it
- paint or layout animation is acceptable only on small, isolated surfaces
- one-shot effects are acceptable more often than continuous motion
- prefer downgrading technique over removing motion entirely
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.

fixing-motion-performance is a skill published in the GitHub repository ratnesh-maurya/cursor-claude-personas (8 stars, last pushed 5mo ago), licensed MIT. It adds 45 tokens to every session and 1,184 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to fixing-motion-performance, differing in 0 lines, and is treated as a copy.
