apple-design

apple-design is a skill for Claude Code, Codex from billythekidz/apple-design-skill. It costs 55 tokens per session (2,729 once invoked), scanned A, a copy of apple-design, MIT.

A set of Apple interface guidelines and design rules for apps and websites styled like Apple products.

In plain words
What is it for?
Use it when designing, building, or reviewing interfaces for iOS, iPadOS, macOS, watchOS, visionOS, or Apple-styled web and mobile apps.
Why use it?
It helps developers make interfaces fit the conventions of Apple platforms and check existing designs for guideline issues.

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is # or: node skills/apple-design/scripts/audit-apple-design.mjs [path].

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

apple-design 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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (assets/tailwind.preset.apple.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Apple Design System & Human Interface Guidelines (HIG)

This skill equips AI coding agents with the exact principles, visual specifications, component architectures, typography metrics, color tokens, motion curves, and automated compliance auditing defined by Apple's Human Interface Guidelines (HIG) across iOS, iPadOS, macOS, watchOS, visionOS, and modern Apple-grade Web UI.

🎯 Operational Modes

Mode 1 — Design & Build from Scratch

When tasked with creating new screens, apps, or web interfaces in Apple style:

  1. Choose the platform-native navigation paradigm (e.g. Bottom Tab Bar for iOS, Sidebar for macOS/iPad, Ornaments for visionOS).
  2. Establish the 8pt spatial grid and continuous squircle curvature (G2 continuity).
  3. Apply the SF Pro / New York typography scale with optical tracking rules.
  4. Implement semantic Dynamic Colors (Light & OLED Dark mode) and Liquid Frosted Glass materials.
  5. Apply Apple spring physics (cubic-bezier(0.25, 1, 0.5, 1)) and tactile active feedback (scale(0.97)).

Mode 2 — Apple HIG Compliance Audit & Scoring

When reviewing an existing codebase, mockup, or component:

  1. Run the audit tool node skills/apple-design/scripts/audit-apple-design.mjs to perform automated static scanning with a 0–100 Scoring Rubric.
  2. Perform exact mathematical WCAG contrast checks and 44×44pt touch-target validations.
  3. Fill out the Apple HIG Audit Scorecard across the 5 core pillars.
  4. Deliver prioritized findings with Confidence Tagging:
    • 🟢 Tool-verified: Statistically measured via CLI tool (e.g., contrast ratio, button dimension, static CSS rules).
    • 🟡 Needs device test: Requires hardware interaction (e.g., Dynamic Type at 300%, Reduce Transparency toggle, VoiceOver speech hierarchy).
    • 🔴 Assumed: Contextual design trade-off or subjective aesthetic evaluation.

🛠️ The Apple HIG Compliance CLI Engine

The built-in audit engine (skills/apple-design/scripts/audit-apple-design.mjs) provides four subcommands:

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.
