firebase-local-env-setup

To set up a Firebase development environment, you must install Node.js version 20 or higher, install the firebase-tools CLI, complete the first-time login process, and link your specific agent setup references.

Firebase CLI setup requires Node.js version 20 or higher. The environment setup process validates your current Node.js version and guides you through installation via nvm with OS-specific steps if needed.

Firebase CLI login for non-localhost environments is handled automatically during the initial setup. The process verifies firebase-tools is installed, checks your login status, and triggers non-localhost authentication when required.

You cannot use this initial Firebase setup process for troubleshooting or refreshing existing environments. This is strictly for first-time setup; updating or troubleshooting an existing environment requires the firebase-basics skill instead.

Firebase local environment setup supports agent-specific configurations by providing dedicated setup documentation references for Gemini CLI, Antigravity, Claude Code, Cursor, GitHub Copilot, and other agents after core validation.

You need firebase-tools to enable Firebase CLI commands within your Node.js development environment. The setup validates its presence to ensure you can authenticate, manage projects, and deploy services correctly.
