What it does

Compose Motion is an agent skill from AThevon/genjutsu. Jetpack Compose animation foundations - animateAsState, AnimatedVisibility, Crossfade, updateTransition, SharedTransitionLayout, gestures.

Its SKILL.md is about 3.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/gestures-compose.md`, `references/recomposition-and-anim.md` and `references/shared-transitions.md`).

It sits in Mobile, covering Android development and Web animation and motion. It works with Jetpack Compose. The repository describes itself as: Creative coding skills for Claude Code, claude.ai and Cowork. Motion, micro-interactions and design systems across Web (GSAP, Motion, Three.js, CSS), Android (Jetpack Compose)…

When your agent uses it

  • Tasks that involve Android development
  • Tasks that involve Web animation and motion

Example prompts

  • “/compose-motion”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Animating layout size instead of transform
  2. LaunchedEffect(true) / LaunchedEffect(Unit) with hidden inputs
  3. Forgetting key in a LazyColumn with item animations
  4. Nesting AnimatedContent inside scrolling list items

What it can do on your machine

Read from SKILL.md and the folder at commit 1f518a7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are kotlin).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com
    • developer.android.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Compose Motion loads about 3.5k tokens when it runs, and up to ~11k if it reads all its reference files. Until then it costs about 39 tokens; SKILL.md has 814 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~3.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~11k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 814 words (~3,493 tokens).

“Rule: climb the ladder only when needed. animate*AsState covers 70% of cases. Reach for Animatable only when you need to interrupt, chain, or read velocity.”
