Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.01726 |
| Opus 5 | $0.00026 | $0.00863 |
| Sonnet 5 | $0.00011 | $0.00345 |
| Haiku 4.5 | $0.00005 | $0.00173 |
Grade A, and why
ui-review 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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 208 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UI Review Skill
Performs comprehensive UI/UX review of SwiftUI code against Apple's Human Interface Guidelines, font best practices, and accessibility standards for iOS and watchOS.
When This Skill Activates
Use this skill when the user:
- Asks to review UI/UX code
- Mentions HIG compliance or Apple guidelines
- Requests accessibility audit
- Wants font usage checked
- Asks about Dynamic Type support
- Requests design review against Apple standards
Review Process
1. Identify Files to Review
- If user specifies files/views, review those
- Otherwise, ask which views to review or scan recent SwiftUI files
- Prioritize user-facing views over components
2. Load Reference Materials
Before starting the review, familiarize yourself with the reference materials by reading the following files in .claude/skills/ui-review/:
- hig-checklist.md - Comprehensive HIG compliance checklist for iOS and watchOS
- font-guidelines.md - Font usage, Dynamic Type, and typography best practices
- accessibility-quick-ref.md - Quick reference for accessibility implementation
You may also reference the official Apple guidelines using WebFetch when needed:
- iOS HIG: https://developer.apple.com/design/human-interface-guidelines/designing-for-ios
- watchOS HIG: https://developer.apple.com/design/human-interface-guidelines/designing-for-watchos
3. Review Categories
Apply these review categories based on the code type:
HIG Compliance:
- Layout & spacing (tap targets, safe areas, padding)
- Navigation patterns (NavigationStack, sheets, alerts)
- Colors & visuals (semantic colors, dark mode, contrast)
- Platform-specific requirements (iOS vs watchOS)
- Loading/empty/error states
Font Usage:
- Dynamic Type support
- System text styles vs fixed sizes
- Font hierarchy and semantic usage
- Custom fonts scaling properly
- Text formatting and truncation
Accessibility:
- Labels and hints for interactive elements
- Traits and roles
- VoiceOver navigation order
- Custom actions
- Dynamic content announcements
- Testing with assistive technologies
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ui-review is a skill published in the GitHub repository rshankras/claude-code-apple-skills (719 stars, last pushed 1mo ago), licensed MIT. It adds 53 tokens to every session and 1,726 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
