animation-performance

Keep web animations inside the frame budget — animate composite-only properties, keep motion off the main thread when the page is busy, and find the cause when an animation drops frames. Covers the layout/paint/composite pipeline, cheaper property swaps, CSS vs WAAPI vs requestAnimationFrame, Framer Motion's hardware-accelerated path, React re-rendering per frame, inherited CSS variable recalculation, blur cost, and when `will-change` actually helps. Use when an animation is janky, choppy, stutters, or drops frames; when choosing which property to animate; when deciding between CSS and JS animation on performance grounds; or when reaching for `will-change` or GPU layers. For choosing easing, duration, or whether to animate at all use animate; for reviewing motion as a whole use review-animations.

    gestures

    Build drag, swipe, and sheet interactions that track the finger 1:1 and stay interruptible. Use when building or fixing anything the user drags, swipes, flings, holds, or dismisses with a gesture — drawers, sheets, swipe-to-dismiss toasts and cards, drag-to-reorder, pull-to-refresh, hold-to-confirm — or when a gesture feels laggy, disconnected from the finger, jumps on release, or can't be caught mid-animation. Triggers on — gesture, drag, draggable, swipe, swipe to dismiss, fling, momentum, velocity, drawer, sheet, bottom sheet, snap points, Vaul, dragConstraints, dragElastic, dragMomentum, onDragEnd, whileDrag, useMotionValue, rubber-band, overscroll, pull to refresh, hold to delete, press and hold, touch-action, dismiss threshold, "doesn't follow my finger", "jumps when I let go", "can't grab it mid-animation".

The file

We split this skill into the rules it gives an agent

7 rules. 3 are common, 2 are distinctive, and 2 are very specific to this project.

  • 3

    Common

    Most of the 10 edited versions we read keep these.

  • 2

    Distinctive

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

No licence file, so all rights are reserved — read it at the source. We count its rules but don't quote them. Read them on GitHub.

“Common” is measured: kept by at least 6 in 10 of the 10 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

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.
