The description field of the SKILL.md. The agent reads only this at startup and decides from it when to load the full skill.

Install Web Design Guidelines

The skills CLI copies the skill into the folder of each agent you pick (Claude Code, Codex, Cursor, Copilot, Gemini CLI, OpenCode, Windsurf...). Add -g for all projects. Needs Node.js 22.20+. docs

npx skills add vercel-labs/agent-skills --skill web-design-guidelines

Copy the skill folder into ~/.claude/skills (all projects) or .claude/skills (this repo). Claude Code picks it up without a restart. docs

npx skills add vercel-labs/agent-skills --skill web-design-guidelines -a claude-code

cp -r /tmp/web-design-guidelines-src/skills/web-design-guidelines ~/.claude/skills/web-design-guidelines

Download the skill folder, zip it, then Customize > Skills > + > Create skill > Upload a skill. Code execution must be on (Settings > Capabilities). docs
