Catalogue stub — full package: raintree-technology/apple-hig-skills

Decision tree

Run this before any Apple platform UI design:

1. Is an HIG skill already installed? Check: ~/.design-agent-skills/skills/hig-foundations/SKILL.md exists.

   • Yes → invoke the specific platform skill and proceed
   • No → go to step 2

2. Do you have shell access?

   • Yes → run the install command below, then invoke the skill
   • No → show the install command; in Claude Code, send it as a chat message starting with ! — add -g for global install or omit for project-only
