Prerequisites

Complete these setup steps before proceeding:

Local Environment Setup: Verify the environment is properly set up so we

can use Firebase tools:

Run npx -y firebase-tools@latest --version to check if the Firebase

CLI is installed.

Verify if the Firebase MCP server is installed using your existing

tools.

CRITICAL: Before configuring any extensions or agent environments

below, you MUST read references/local-env-setup.md.

DO NOT SKIP this step: if 'firebase-basics' is the only

Firebase skill available to you, you must follow the reference for your agent environment to set up the full suite of Firebase skills:

Gemini CLI: Review

references/setup/gemini_cli.md

Antigravity: Review

references/setup/antigravity.md

Android Studio: Review

references/setup/android_studio.md

Claude Code: Review

references/setup/claude_code.md

Cursor: Review

references/setup/cursor.md

GitHub Copilot: Review

references/setup/github_copilot.md

Other Agents: Review

references/setup/other_agents.md

Authentication: Ensure you are logged in to Firebase so that commands

have the correct permissions. Run npx -y firebase-tools@latest login. For environments without a browser (e.g., remote shells), use npx -y firebase-tools@latest login --no-localhost.

The command should output the current user.
If you are not logged in, follow the interactive instructions from this

command to authenticate.

Active Project:

Most Firebase tasks require an active project context.

> !IMPORTANT] > For Agents: Before proceeding with project configuration, you MUST pause and ask the developer if they prefer to: > 1. Provide an existing Firebase Project ID, or > 2. Create a new Firebase project.

If using an existing Project ID:

Check the current project by running npx -y firebase-tools@latest use.
If the command outputs Active Project: <project-id>, confirm with the user if this is the intended project.
If not, or if no project is active, set the project provided by the user:

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

If creating a new project:

Run the following command to create it: bash npx -y firebase-tools@latest projects:create <project-id> --display-name "<display-name>" Note: The `<project-id>` must be 6-30 characters, lowercase, and can contain digits and hyphens. It must be globally unique.

Firebase Usage Principles

Adhere to these principles:

Use npx for CLI commands: To ensure you always use the latest version of the Firebase CLI, always prepend commands with npx -y firebase-tools@latest instead of just firebase. For example, use npx -y firebase-tools@latest --version. NEVER suggest the naked firebase command as an alternative.
Prioritize official knowledge: For any Firebase-related knowledge, consult the developerknowledge_search_documents MCP tool before falling back to Google Search or your internal knowledge base. Including "Firebase" in your search query significantly improves relevance.
Follow Agent Skills for implementation guidance: Skills provide opinionated workflows (CUJs), security rules, and best practices. Always consult them to understand how to implement Firebase features correctly instead of relying on general knowledge.
Use Firebase MCP Server tools instead of direct API calls: Whenever you need to interact with remote Firebase APIs (such as fetching Crashlytics logs or executing Data Connect queries), use the tools provided by the Firebase MCP Server instead of attempting manual API calls.
Keep Plugin / Agent Skills updated: Since Firebase best practices evolve quickly, regularly check for and install updates to their Firebase plugin or Agent Skills. Similarly, if you encounter issues with outdated tools or commands, follow the steps below based on your agent environment:

Antigravity: Follow references/refresh/antigravity.md
Gemini CLI: Follow references/refresh/gemini-cli.md
Claude Code: Follow references/refresh/claude.md
Cursor: Follow references/refresh/other-agents.md
Android Studio: Follow references/refresh/android_studio.md
Others: Follow references/refresh/other-agents.md

Automate Config File Retrieval: When setting up iOS or Android apps, do NOT direct users to the Firebase Console to download google-services.json or GoogleService-Info.plist. Instead, use the Firebase CLI to fetch the config programmatically:

For Android: npx -y firebase-tools@latest apps:sdkconfig ANDROID <APP_ID> --project <PROJECT_ID>
For iOS: npx -y firebase-tools@latest apps:sdkconfig IOS <APP_ID> --project <PROJECT_ID>

Save the output to the appropriate location (e.g., app/google-services.json for Android, or a path to be linked by xcode-project-setup for iOS).

References

Initialize Firebase: See references/firebase-service-init.md when you need to initialize new Firebase services using the CLI.
Exploring Commands: See references/firebase-cli-guide.md to discover and understand CLI functionality.
SDK Setup: For detailed guides on adding Firebase to your app:
Web: See references/web_setup.md
Android: See references/android_setup.md
iOS: See references/ios_setup.md

Common Issues

Login Issues: If the browser fails to open during the login step, use

npx -y firebase-tools@latest login --no-localhost instead.

Genkit:

If using Genkit, install the skills: bash npx skills add genkit-ai/skills

Prompt

I need to add Firebase to my Android app build and retrieve the app's configuration file. Please obtain the necessary config data using command line commands instead of asking me to navigate the web console, and save it to my app directory.

Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
