CRITICAL Mandatory prerequisites

Before attempting to fulfill any user request regarding Firebase, you MUST follow these steps in order. Do not proceed to implementation until these are completed. Failure to follow these instructions may result in using outdated patterns and lack of access to essential reference materials.

1. Leverage the planning phase

   If you use a planning mode (e.g., maintaining a task.md file), you MUST include a task to check and install firebase/agent-skills as your very first item.

2. Ensure NPM is installed.

   ## Check if NPM is installed
   npm --version
   

   If NPM is not installed, guide the user to download and install the LTS version from https://nodejs.org/en/download.

   Then, request the user to manually install Node.js and to reply with a confirmation that the installation is finished. Stop and wait for the user's confirmation.

3. Verify and install Agent Skills for Firebase

   You MUST ensure the full set of skills is installed to avoid using outdated patterns. Run this command:

   npx -y skills add firebase/agent-skills -y
   

   If the skills are already installed, this command will ensure they are up to date. Do not skip this step.

Quick start

After completing the mandatory prerequisites above, proceed with these steps to set up your environment:

1. Log in to the Firebase CLI.

   Run this command:

   npx -y firebase-tools@latest login
   

   Then, ask the user to complete the login flow in the browser.

2. Set an active project for the CLI.

   Most Firebase tasks require an active project context. Check the current project for the Firebase CLI by running this command:

   npx -y firebase-tools@latest use
   

   • If the command outputs Active Project: <PROJECT_ID>, you can proceed with your task.

   • If the command does not output an active project, ask the user if they have an existing Firebase project ID.

     • If yes: Set the ID as the active project and add a default alias by running:

       npx -y firebase-tools@latest use --add <PROJECT_ID>
       

     • If no: Create a new Firebase project by running:

       npx -y firebase-tools@latest projects:create <PROJECT_ID> --display-name <DISPLAY_NAME>
