What it does
Common Mobile Animation is an agent skill from HoangNguyen0403/agent-skills-standard. Apply motion design principles for mobile apps covering timing curves, transitions, gestures, and performance-conscious animations. Use when implementing screen transitions, gesture-driven interactions, shared-element animations, or optimizing animation frame rates on iOS, Android, or Flutter.
Its SKILL.md is about 670 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-patterns.md` and `references/implementation.md`).
It sits in Mobile, covering Cross-platform mobile apps and Motion graphics. It works with Flutter, iOS and Android. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.
When your agent uses it
- Implementing screen transitions
- Gesture-driven interactions
- Shared-element animations
- Optimizing animation frame rates on iOS
Example prompts
- “/common-mobile-animation”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Choose duration from timing table based on interaction type.
- Select easing curve per platform — Curves.fastOutSlowIn (Material) or easeInOut (iOS). Never use linear.
- Animate GPU-friendly properties (transform, opacity). Avoid width/height which trigger layout.
- Wire gestures using onPan / interactivePopGesture for fluid, interruptible UX.
- Verify frame rate in profiler — target 60fps with no jank frames.
What it can do on your machine
Read from SKILL.md and the folder at commit b529c2d. 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.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Common Mobile Animation loads about 671 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 80 tokens; SKILL.md has 211 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.

- description
- Apply motion design principles for mobile apps covering timing curves, transitions, gestures, and performance-conscious animations. Use when implementing screen transitions, gesture-driven interactions, shared-element animations, or optimizing animation frame rates on iOS, Android, or Flutter.
Mobile Animation
Priority: P1 (HIGH)
Timing Standards
| Duration | Range | Use Case |
|---|---|---|
| Short | 100-150ms | Toggles, cell press |
| Medium | 250-350ms | Navigation, modals |
| Long | 400-600ms | Shared element, complex state |
Hard limit: Never exceed 600ms for any animation.
Workflow
- Choose duration from timing table based on interaction type.
- Use 250-350ms for medium navigation/modals and 400-600ms for long shared-element or complex-state transitions; state the selected range in quick-start examples.
- A quick-start example must demonstrate the Long
400-600msshared-element or complex-state pattern; do not substitute the Medium range.
- Select easing curve per platform —
Curves.fastOutSlowIn(Material) oreaseInOut(iOS). Never uselinear. - Animate GPU-friendly properties (
transform,opacity). Avoidwidth/heightwhich trigger layout. - Wire gestures using
onPan/interactivePopGesturefor fluid, interruptible UX. - Verify frame rate in profiler — target 60fps with no jank frames.
See implementation examples for Flutter and iOS animation patterns.
References
Anti-Patterns
- No linear easing: Feels robotic; always use platform-standard curves.
- No layout thrashing: Avoid animating properties that trigger layout (width, padding).
- No memory leaks: Always
dispose()AnimationControllers in Flutter; invalidate timers in iOS. - No blocking UI: Run heavy calculations outside animation frames.
