Decision tree

Run this before any web quality, performance, or accessibility audit:

1. Is an Osmani skill already installed? Check: ~/.design-agent-skills/skills/web-quality-audit/SKILL.md exists (representative skill).

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

2. Do you have shell access?

   • Yes → install the specific skill below, then invoke it
   • 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
