-    The `/skills` path installs CopilotKit's published skills only (not the repository's internal tooling), and `-y` installs **all** of them without prompting you to pick them one by one. This pulls the latest skills directly from the CopilotKit repository into your project's skills directory (e.g. `.claude/skills/` for Claude Code) — installing per-project keeps each project pinned to the skills that match its CopilotKit version. The CopilotKit MCP server is also auto-wired so your agent has live documentation access.
