npx skills add github/awesome-copilotInstall to a specific agent
Pick the agent you use. The CLI writes the skill to that agent's standard skill directory.

Use it
Once installed, ask your agent to "use the excalidraw-diagram-generator skill" or describe what you want (e.g. "Generate Excalidraw diagrams from natural language descriptions. Use when asked"). Most agents auto-discover the skill from its SKILL.md description — no slash command needed.
