What it does
Swiftui Motion is an agent skill from AThevon/genjutsu. SwiftUI animation foundations - withAnimation, transitions, matchedGeometryEffect, PhaseAnimator, KeyframeAnimator, springs, gestures.
Its SKILL.md is about 4k 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-swiftui.md`, `references/phase-keyframe-deep.md` and `references/springs-cheatsheet.md`).
It sits in Mobile, covering iOS development. It works with SwiftUI and iOS. 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 iOS development
Example prompts
- “/swiftui-motion”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Deprecated .animation form (no value binding)
- Animating frame size directly
- Scale to 0 (the vanish-into-nothing trap)
- withAnimation inside body
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 swift).
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):
developer.apple.comgithub.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
Swiftui Motion loads about 4k tokens when it runs, and up to ~10k if it reads all its reference files. Until then it costs about 37 tokens; SKILL.md has 1,030 words of instructions outside code blocks.
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 1,030 words (~3,960 tokens).
“Rule: start with withAnimation. Reach for PhaseAnimator only when you have 3+ ordered states. Reach for KeyframeAnimator only when you need parallel time-based tracks.”
