What it does
Hig Components Layout is an agent skill from raintree-technology/hig-doctor. Apple Human Interface Guidelines for layout and navigation components. Use this skill when the user asks about "sidebar", "split view", "tab bar", "tab view", "scroll view", "window design", "panel", "list view", "table view", "column view", "outline view", "navigation structure", "app layout", "boxes", "ornaments", or organizing content hierarchically in Apple apps. Also use when the user says "how should I organize my app", "what navigation pattern should I use", "my layout breaks on iPad", "how do I build a…
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files, including reference files (for example `references/boxes.md`, `references/column-views.md` and `references/lists-and-tables.md`).
It sits in Mobile, covering iOS development. The repository describes itself as: Apple HIG reference and cross-framework UI audit tooling for agents. The licence is MIT.
When your agent uses it

What it can do on your machine
Read from SKILL.md and the folder at commit 3ec08f5. 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
Links to these hosts (documentation or services it may open):
raintree.technology
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
Hig Components Layout loads about 1.6k tokens when it runs, and up to ~7.3k if it reads all its reference files. Until then it costs about 210 tokens; SKILL.md has 599 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.

- Apple Human Interface Guidelines for layout and navigation components. Use this skill when the user asks about "sidebar", "split view", "tab bar", "tab view", "scroll view", "window design", "panel", "list view", "table view", "column view", "outline view", "navigation structure", "app layout", "boxes", "ornaments", or organizing content hierarchically in Apple apps. Also use when the user says "how should I organize my app", "what navigation pattern should I use", "my layout breaks on iPad", "how do I build a sidebar", "should I use tabs or a sidebar", or "my app doesn't adapt to different screen sizes".

Apple HIG: Layout and Navigation Components
Check for .claude/apple-design-context.md before asking questions. Use existing context and only ask for information not already covered.
Key Principles
Organize hierarchically. Structure information from broad categories to specific details. Sidebars for top-level sections, lists for browsable items, detail views for individual content.
Use standard navigation patterns. Tab bars for flat navigation between peer sections (iPhone). Sidebars for deep hierarchical navigation (iPad, Mac). Match the pattern to the information architecture and platform.
Adapt to screen size. Three-column on iPad collapses to single-column on iPhone. Use size classes and adaptive APIs (NavigationSplitView) for automatic adaptation.
Support multitasking on iPad. Respond gracefully to Split View, Slide Over, and Stage Manager. Test at every split ratio and size class transition.
Maintain spatial consistency on visionOS. Windows, volumes, and ornaments in shared space. Position predictably. Use ornaments for toolbars and controls without occluding content.
Use scroll views for overflow content. Enable paging for discrete content units. Support pull-to-refresh where appropriate. Respect safe areas.
Keep navigation predictable. Users should always know where they are, how they got there, and how to go back. Use back buttons, breadcrumbs, and clear section titles.
Prefer system components. UINavigationController, UISplitViewController, NavigationSplitView, and TabView provide built-in adaptivity, accessibility, and state restoration.

Navigation Pattern Selection
| App Structure | Recommended Pattern | Platform Adaptation |
|---|---|---|
| 3-5 peer top-level sections | Tab Bar | iPhone: bottom tab bar. iPad: sidebar (.sidebarAdaptable, iPadOS 18+). Mac: sidebar or toolbar tabs |
| Deep hierarchical content | Sidebar + NavigationSplitView | iPhone: single column stack. iPad: two/three columns. Mac: full multi-column |
| Deep file/folder tree | Column View | Mac: Finder-style. iPad: adaptable. iPhone: push navigation |
| Flat list with detail | Split View (two column) | iPhone: push/pop stack. iPad/Mac: primary + detail columns |
| Document-based with inspectors | Window + Panels | Mac: main window with inspector. iPad: sheet or popover |
| Spatial app with tools | Window + Ornaments | visionOS: ornaments on window. Other platforms: toolbars |
Layout Adaptation Checklist
- Compact width (iPhone portrait): Navigation collapses to single stack? Tab bars visible?
- Regular width (iPad landscape, Mac): Navigation expands to sidebar + detail? Space used well?
- Multitasking (iPad): Adapts at every split ratio? Works in Slide Over?
- Accessibility: Supports Dynamic Type at all sizes? VoiceOver order logical?
- Orientation: Content reflows between portrait and landscape?
- visionOS: Windows positioned ergonomically? Ornaments accessible? Depth meaningful?
Output Format
- Recommended navigation pattern with rationale for the app's information architecture.
- Layout hierarchy from root container down (e.g., TabView > NavigationSplitView > List > Detail).
- Platform adaptation across targeted platforms and size classes.
- Size class behavior at each transition.
Questions to Ask
- What is the app's information architecture? (Sections, hierarchy depth, top-level categories?)
- How many top-level sections?
- Which platforms?
- Need multitasking on iPad?
- SwiftUI or UIKit?
