What it does

Swiftui Animation is an agent skill from dpearson2699/swift-ios-skills. Implement, diagnose, or review SwiftUI motion using explicit and scoped implicit animations, springs, transitions, PhaseAnimator, KeyframeAnimator, matched geometry or navigation zoom, SF Symbol effects, and custom Animation types. Use when views should animate on state changes, insertion, removal, navigation, or multi-step choreography, or when motion must respect Reduce Motion and Swift concurrency.

Its SKILL.md is about 3.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `evals/evals.json`, `references/animation-advanced.md` and `references/core-animation-bridge.md`).

It sits in Mobile, covering iOS development. It works with SwiftUI, Swift and iOS. The repository describes itself as: Agent Skills for iOS 26+, Swift 6.3, SwiftUI, and modern Apple frameworks.

When your agent uses it

  • Views should animate on state changes
  • Multi-step choreography
  • Motion must respect Reduce Motion and Swift concurrency

Example prompts

  • “/swiftui-animation”

Workflow steps

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

  1. Identify the animation category
  2. Choose the animation curve
  3. Apply and verify
  4. Using bare .animation(_:) when you need precise scope
  5. Expensive work or actor-isolated reads inside animation closures
  6. Missing reduce motion support
  7. Multiple matchedGeometryEffect sources
  8. Using DispatchQueue or UIView.animate
  9. Forgetting animation on ContentTransition
  10. navigationTransition on wrong view

What it can do on your machine

Read from SKILL.md and the folder at commit 8d90fd1. 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):

    • sosumi.ai

    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 Animation loads about 3.9k tokens when it runs, and up to ~15k if it reads all its reference files. Until then it costs about 106 tokens; SKILL.md has 747 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~106
When it runs · the whole SKILL.md, loaded when a task matches
~3.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~15k

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 747 words (~3,900 tokens).

“Review, write, and fix SwiftUI animations. Apply modern animation APIs with correct timing, transitions, and accessibility handling using Swift 6.3 patterns.”
