Install Engineering OS globally on this machine, for yourself (the coding agent reading this).
Repo: https://github.com/soummyaanon/engineering-os

1. Read the installer before running it: https://engineering-os-hazel.vercel.app/install
2. Work out your agent id for the skills CLI. Common ids: claude-code, codex, cursor, gemini-cli, github-copilot, windsurf, opencode, cline, roo, amp. If unsure, run: npx skills add --help
3. Run the installer:
   - If you are Claude Code:  curl -fsSL https://engineering-os-hazel.vercel.app/install | bash
   - Any other agent:         curl -fsSL https://engineering-os-hazel.vercel.app/install | bash -s -- --agent <your-agent-id>
4. If the installer says it doesn't know your agent's rules file, add the contents of ~/engineering-os/CLAUDE.md to your own global instructions/rules file.
5. Show me the installer's summary, then tell me to start a new session so the skills load.

It needs git, node (npx) and python3. If one is missing, stop and tell me how to install it instead of working around it.
