Quick heads up that the URL to the installation script points to the wrong subdomain.

Located here, in section "Quick Install", HTML class seems to be install-cmd:
https://www.agent-zero.ai/p/docs/get-started/#installation

Current URL:
curl -fsSL https://unix.agent-zero.ai | bash

Likely the correct URL:
curl -fsSL https://bash.agent-zero.ai | bash
