Firebase agent skills are the official Firebase skills that teach coding agents setup, Auth, Firestore and deploys.

Firebase agent skills are Firebase’s own collection of skills in the Agent Skills format: instructions, recommended practices and automation scripts for Firebase tasks such as adding sign-in, provisioning Cloud Firestore or deploying a web app (Firebase docs). Firebase says they work with any assistant that supports skills, naming Antigravity, Claude Code, Codex and Cursor. The source is the firebase/agent-skills repository under the Apache 2.0 license; the Claude and Codex plugin manifests in it are at version 1.1.0.

The skills listed in the docs cover first-time setup (firebase-basics), Authentication (firebase-auth-basics), Cloud Firestore, Firebase SQL Connect (firebase-data-connect-basics), classic Hosting (firebase-hosting-basics), App Hosting for Next.js and Angular (firebase-app-hosting-basics), Firebase AI Logic (firebase-ai-logic-basics), Crashlytics (firebase-crashlytics), Remote Config (firebase-remote-config-basics) and a Firestore security rules auditor. The repository also carries an xcode-project-setup skill for adding Swift packages to iOS projects and extension-to-functions-codebase for turning a Firebase Extension into a Cloud Functions codebase.

Firebase pitches them as a complement to the Firebase MCP server: the server acts on your projects and data, and the skills tell the agent how to use it and the Firebase CLI. The repository’s .mcp.json starts that server through npx firebase-tools, and the Codex plugin manifest declares both skills and MCP. Skills load by progressive disclosure: the agent reads short metadata first and the full instructions only when a request matches (Firebase docs).

Questions

Are Firebase agent skills official?

Yes. Firebase documents them on firebase.google.com, and the repository is published under the Firebase GitHub organization with Google LLC named as the skills’ author.

How do I install Firebase agent skills in Claude Code?

Run claude plugin marketplace add firebase/agent-skills, then claude plugin install firebase@firebase. The plugin brings the skills and the Firebase MCP server configuration.

Do I need the Firebase MCP server as well?

Firebase designed the skills to complement the MCP server: the skills give instructions, and the server lets the agent act on your Firebase projects and data. The Claude Code and Codex plugins set up both. Skills such as firebase-auth-basics state in their metadata that they are best used with the Firebase CLI but do not require it.

How do I call a Firebase skill directly?

Agents load a skill when its description matches the request. Firebase’s docs say you can also invoke one by typing / in the agent chat and searching for the skill name.
