Firebase Basics

CRITICAL Mandatory prerequisites

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.
   bash

   ## 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   You MUST ensure the full set of skills is installed to avoid using outdated patterns.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:
   bash

   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

1. Log in to the Firebase CLI.
   Run this command:
   bash

   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:
   bash

   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:
       bash

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

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

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