What it does
Hig Platforms is an agent skill from raintree-technology/hig-doctor. Apple Human Interface Guidelines for platform-specific design. Use this skill when the user asks about "designing for iOS", "iPad app design", "macOS design", "tvOS", "visionOS", "watchOS", "Apple platform", "which platform", platform differences, platform-specific conventions, or multi-platform app design. Also use when the user says "should I design differently for iPad vs iPhone", "how does my app work on visionOS", "what's different about macOS apps", "porting my app to another platform", "universal app…
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `references/designing-for-games.md`, `references/designing-for-ios.md` and `references/designing-for-ipados.md`).
It sits in Mobile, covering iOS development. It works with iOS and macOS. 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
- The user asks about designing for iOS
- IPad app design
- Platform differences
- Platform-specific conventions
Example prompts
- “designing for iOS”
- “iPad app design”
- “macOS design”
- “/hig-platforms”

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 Platforms loads about 1.3k tokens when it runs, and up to ~5.3k if it reads all its reference files. Until then it costs about 195 tokens; SKILL.md has 501 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 HIG: Platform Design
Check for .claude/apple-design-context.md before asking questions. Use existing context and only ask for information not already covered.
Key Principles
Each platform has a distinct identity. Do not port designs between platforms. Respect each platform's conventions, interaction models, and user expectations.
iOS: touch-first. Direct manipulation on a handheld screen. Optimize for one-handed use. Navigation uses tab bars and push/pop stacks.
iPadOS: expanded canvas. Support Split View, Slide Over, and Stage Manager. Use sidebars and multi-column layouts. Support pointer and keyboard alongside touch.
macOS: pointer and keyboard. Dense information display is acceptable. Use menu bars, toolbars, and keyboard shortcuts extensively. Windows are resizable with precise control.
tvOS: remote and focus. Viewed from a distance. Design for the Siri Remote with focus-based navigation. Large text, simple layouts, linear navigation.
visionOS: spatial interaction. 3D environment using windows, volumes, and spaces. Eye tracking for targeting, indirect gestures for interaction. Respect ergonomic comfort zones.
watchOS: glanceable and brief. Information consumable at a glance. Brief interactions. Digital Crown, haptics, and complications for timely content.
Games: own paradigm. Free to define in-game interaction models, but still respect platform conventions for system interactions (notifications, accessibility, controllers).

Decision Framework
Identify the primary use context. On the go (iOS/watchOS), at a desk (macOS), on the couch (tvOS), spatial environment (visionOS)?
Match input to interaction. Touch for direct manipulation, pointer for precision, gaze+gesture for spatial, Digital Crown for quick scrolling, remote for focus navigation.
Adapt, don't replicate. A macOS sidebar becomes a tab bar on iPhone. A visionOS volume has no equivalent on watchOS. Translate intent, not implementation.
Leverage platform strengths. Live Activities on iOS, Desktop Widgets on macOS, complications on watchOS, immersive spaces on visionOS.
Maintain brand consistency while respecting each platform's visual language and interaction patterns.
Output Format
- Platform-specific recommendations citing relevant HIG sections.
- Platform differences table comparing navigation, input, layout, and conventions.
- Implementation notes per platform including recommended APIs and adaptation strategies.
Questions to Ask
- Which platforms are you targeting?
- New app or adapting an existing one? If existing, which platform is the base?
- SwiftUI or UIKit/AppKit?
- Need to support older OS versions?
- Primary use context? (On the go, desk, couch, spatial, glanceable?)
