Compose Motion (Jetpack Compose Animation)

A decision-tree style skill for picking the right Jetpack Compose animation API and avoiding jank-inducing anti-patterns.

Dev & CodingIntermediate★ 436⑂ 31AI score 9/10Last updated: Oct 5, 2026

What it does

Guides Claude to pick the correct Compose animation API and write idiomatic, performant motion code for Android Compose and Compose Multiplatform.

  • API decision table: single value → animate*AsState; mount/unmount → AnimatedVisibility; layout swap → AnimatedContent; multi-property → updateTransition; manual/interruptible → Animatable; hero → SharedTransitionLayout
  • Opinionated spring() presets (stiffness/damping) for modals, tactile taps, bouncy reveals and 1:1 drag tracking
  • Gesture map: draggable, anchoredDraggable (replaces swipeable), transformable, pointerInput
  • Four BAD/GOOD anti-patterns: animating layout size, LaunchedEffect(true) misuse, missing LazyColumn keys, nesting AnimatedContent per row
  • Reduced-motion handling via animator duration scale with a snap() fallback

Who it's for

  • Android Compose / CMP developers building real UI motion
  • Anyone debugging scroll jank or stuttering transitions
  • Teams implementing hero transitions, tab switches, or loading crossfades

Examples

  1. "Add a shared-element hero transition from list to detail" → generates SharedTransitionLayout with matching rememberSharedContentState(key) scopes
  2. "My expanding card drops frames" → swaps the animated width for a graphicsLayer scale or animateContentSize
  3. "Slide tabs horizontally on switch" → AnimatedContent with togetherWith and SizeTransform

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/_jutsu/compose-motion folder from the GitHub repo AThevon/genjutsu into my ~/.claude/skills/compose-motion/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/AThevon/genjutsu.git && mkdir -p ~/.claude/skills && cp -r genjutsu/skills/_jutsu/compose-motion ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/AThevon/genjutsu.git
  3. Create the skills directory: mkdir -p ~/.claude/skills
  4. Copy this skill: cp -r genjutsu/skills/_jutsu/compose-motion ~/.claude/skills/
  5. (Recommended) It links to references/ files and sibling skills (../motion-principles, ../compose-graphics), so copy the whole bundle instead: cp -r genjutsu/skills/_jutsu ~/.claude/skills/
  6. Restart Claude Code and try a prompt such as "animate this Compose screen transition".
