Hig Platforms is a community-contributed Claude Code skill in the mobile sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/hig-platforms/ and loads when your prompt matches the skill's trigger.
When to invoke it: 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 design", or "what input methods does this platform use". Cross-references: hig-foundations for shared design foundations, hig-patterns for interaction patterns, hig-components-layout for navigation structures, hig-components-content for content display.
The Hig Platforms skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It is part of the open ClaudSkills registry, a community-curated catalog of 56,000+ capabilities you can install for Claude Code — the Claude CLI agent.
