gsap-performance
by greensockgsap-performance is the GSAP performance skill for Frontend Development. Use it to reduce jank, avoid layout thrashing, prefer transforms and opacity, apply will-change wisely, and batch reads and writes for smoother 60fps animations. It’s best when you need practical gsap-performance usage guidance for existing motion code.
This skill scores 78/100, which means it is a solid directory listing for users optimizing GSAP animations. It gives agents a clear trigger, concrete performance rules, and enough operational guidance to reduce guesswork compared with a generic prompt, though it is more specialized than a full end-to-end workflow skill.
- Explicit triggerability for animation performance work: use when optimizing GSAP animations, reducing jank, or targeting smooth 60fps.
- Concrete, actionable guidance: prefer transforms and opacity, avoid layout-heavy properties, and use will-change/batching.
- Good cross-skill context: points users toward related gsap-core, gsap-timeline, and gsap-scrolltrigger skills.
- No install command, scripts, or support files, so users only get a standalone guidance document rather than a broader tool-backed workflow.
- Limited workflow depth and no repo/file references; it helps with optimization decisions but does not provide a full diagnostic or automated performance procedure.
Overview of gsap-performance skill
The gsap-performance skill is the GSAP guidance set for making animations faster, smoother, and less likely to jank. It is most useful when you already know the animation goal, but need help choosing the least expensive implementation for Frontend Development. The core job is to keep motion on the compositor when possible, avoid layout thrashing, and reduce paint-heavy work that can break 60fps.
Who should use gsap-performance
Use the gsap-performance skill if you are tuning an existing GSAP animation, reviewing a motion-heavy UI, or deciding whether a proposed animation is safe for production. It is a strong fit for front-end engineers, UI developers, and AI-assisted coding workflows that need a performance-aware answer instead of a generic animation prompt.
What it helps you decide
This skill helps you choose between transform-based motion and layout-based motion, understand when will-change is useful, and recognize when batching reads and writes matters. That makes gsap-performance especially valuable when the real question is not “how do I animate this?” but “how do I animate this without dropping frames?”
Where it fits in the GSAP stack
gsap-performance is best used alongside gsap-core for basic animation construction and gsap-scrolltrigger when scroll-driven motion is involved. If your problem is timeline structure or choreography rather than runtime cost, another GSAP skill may be a better first stop.
How to Use gsap-performance skill
Install it in the right context
For a directory-based skill setup, install with:
npx skills add greensock/gsap-skills --skill gsap-performance
Use the gsap-performance install step in the project where you actually need animation guidance, then apply the skill while you are drafting, reviewing, or refactoring the motion code. If you are working across multiple apps, install it in the one with the performance-sensitive animation workload.
Give the skill a performance-shaped prompt
The gsap-performance usage pattern works best when you provide the animation target, the property being animated, the environment, and the symptom. A weak prompt says “make this smoother.” A stronger prompt says: “Optimize this GSAP entrance animation for mobile Safari; it currently animates top and width, and I need the same effect with less layout cost.”
Useful prompt ingredients:
- the element type and count, such as one card, many list items, or a full hero section
- the current properties being animated
- the browser or device concern
- the visible problem, such as jank, lag, scroll stutter, or frame drops
- any constraints, such as no markup changes or no visual change
Read the skill files in a practical order
Start with SKILL.md because it contains the decision rules the skill is built around. For installation-oriented review, read the sections on when to use the skill, transform and opacity choices, will-change, and batching reads and writes first. If you are comparing skills, also skim related GSAP guidance so you do not force gsap-performance to solve timeline design problems it was not meant to own.
Apply the main workflow
Use the skill by translating motion goals into cheaper rendering work:
- Replace layout-triggering animation properties with transforms when the visual result allows it.
- Use opacity for fades instead of animating painted geometry.
- Add
will-change: transform;only on elements that truly animate. - Avoid alternating DOM reads and writes inside the same hot path.
- Re-test on the slowest device or browser you support, not just desktop Chrome.
The gsap-performance guide is most helpful when you already have a draft animation and need to make it cheaper without changing the look.
gsap-performance skill FAQ
Is gsap-performance for Frontend Development only?
It is most relevant there, yes. The skill is aimed at browser rendering behavior, DOM animation cost, and UI smoothness. If your work is server-side, data-only, or not tied to runtime animation, this skill is usually the wrong fit.
How is it different from a normal prompt?
A normal prompt may suggest “use transforms” in general terms, but gsap-performance gives you a more reliable decision path for GSAP-specific motion. That matters when you need practical tradeoffs, such as whether to preserve a design by switching to transforms or whether a layout change is worth the cost.
Do beginners need deep GSAP knowledge first?
No, but they do need a concrete animation goal. The skill is easiest to use when you can describe the element, motion, and pain point. If you are still learning GSAP basics, pair it with gsap-core rather than expecting gsap-performance to teach animation syntax from scratch.
When should I not use gsap-performance?
Skip it when the issue is not performance, or when the main problem is orchestration, sequencing, or scroll logic rather than rendering cost. It is also not the right first choice if you need a full visual animation spec; it is best at optimization and implementation guidance, not creative direction.
How to Improve gsap-performance skill
Give better before-and-after targets
The best gsap-performance results come from clear constraints: what must stay visually the same, what can change, and what device class matters. For example, “Keep the card reveal style, but eliminate layout shifts and reduce mobile Safari jank” is more actionable than “make this faster.”
Surface the actual bottleneck
A common failure mode is asking the skill to optimize the wrong thing. If the bottleneck is a heavy shadow, large blur, too many animated elements, or expensive scroll handlers, say so. The more precisely you identify the cost, the more useful the gsap-performance usage guidance becomes.
Iterate with a specific test case
After the first output, validate on the smallest reproducible case and then scale up. If the animation looks good on one element but fails on a list of 30, ask for batching, sequencing, or property changes that reduce per-frame work. That is where the gsap-performance skill adds the most value: not in inventing animation, but in making the real version safe to ship.
