nucleus-apple-mcp: Skill for Claude Code

.agents/skills/animate/SKILL.md

animate is a skill for Claude Code, Codex from zish-rob-crur/nucleus-apple-mcp. It costs 25 tokens per session (1,895 once invoked), scanned A, a copy of animate, MIT.

A design-review guide for adding purposeful movement, such as animations and small interaction effects, to a website or app.

In plain words
What is it for?
Use it to review a feature, find useful opportunities for animation, and improve how interactions communicate what is happening.
Why use it?
It helps motion explain changes and provide feedback while taking the audience, tone, and performance limits into account.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is zish-rob-crur/nucleus-apple-mcp's own configuration. It tells Claude Code and Codex how to work on nucleus-apple-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything nucleus-apple-mcp configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

animate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

100% identical to animate — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Analyze a feature and strategically add animations and micro-interactions that enhance understanding, provide feedback, and create delight.

MANDATORY PREPARATION

Context Gathering (Do This First)

You cannot do a great job without having necessary context, such as target audience (critical), desired use-cases (critical), brand personality/tone (playful vs serious, energetic vs calm), and performance constraints.

Attempt to gather these from the current thread or codebase.

  1. If you don't find exact information and have to infer from existing design and functionality, you MUST STOP and STOP and call the AskUserQuestionTool to clarify. whether you got it right.
  2. Otherwise, if you can't fully infer or your level of confidence is medium or lower, you MUST STOP and call the AskUserQuestionTool to clarify. clarifying questions first to complete your context.

Do NOT proceed until you have answers. Guessing leads to inappropriate or excessive animation.

Use frontend-design skill

Use the frontend-design skill for design principles and anti-patterns. Do NOT proceed until it has executed and you know all DO's and DON'Ts.


Assess Animation Opportunities

Analyze where motion would improve the experience:

  1. Identify static areas:

    • Missing feedback: Actions without visual acknowledgment (button clicks, form submission, etc.)
    • Jarring transitions: Instant state changes that feel abrupt (show/hide, page loads, route changes)
    • Unclear relationships: Spatial or hierarchical relationships that aren't obvious
    • Lack of delight: Functional but joyless interactions
    • Missed guidance: Opportunities to direct attention or explain behavior
  2. Understand the context:

    • What's the personality? (Playful vs serious, energetic vs calm)
    • What's the performance budget? (Mobile-first? Complex page?)
    • Who's the audience? (Motion-sensitive users? Power users who want speed?)
    • What matters most? (One hero animation vs many micro-interactions?)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
