[Video](https://www.youtube.com/watch?v=8V_I4jsXXyo) Firebase agent skills ([GitHub](https://github.com/firebase/agent-skills)) are portable, self-contained modules of Firebase-specific knowledge, instructions, and workflows. They're designed to help AI assistants understand Firebase best practices and execute complex tasks with higher accuracy and lower token cost. For a full list of the Firebase agent skills, see [Available skills](https://firebase.google.com/docs/ai-assistance/agent-skills.md.txt#available-skills). ## Get started Firebase agent skills work with any AI assistant that supports skills, including Antigravity, Claude Code, Codex, and Cursor. ### Install Firebase agent skills In most cases, Firebase agent skills can be installed in your preferred editor with a single command: ### Antigravity - **Option 1: Global-level access** Firebase agent skills are included in the **Firebase** plugin in the [Antigravity Marketplace](https://antigravity.google/docs/marketplace) (and as a **Build with Google** integration bundle). Install the plugin using any of the following options: - From the Antigravity Marketplace: Click **Customizations** , select the **Marketplace** tab, and then click **+** on the **Firebase** plugin card. - In Antigravity CLI: Run `/plugin install firebase@agent-marketplace` (or run `/plugin` and install **Firebase** from the **Discover** tab). Plugins installed in Antigravity also sync automatically to Antigravity CLI. - During onboarding: Select the checkbox for the Firebase stack. - **Option 2: Project-level access** Run the following command in your project's directory: ```bash npx skills add firebase/agent-skills --agent=antigravity ``` ### Claude Code Run the following commands in your terminal: ```bash claude plugin marketplace add firebase/agent-skills claude plugin install firebase@firebase ``` ### Codex - **Option 1: Codex terminal** Run the following commands in your terminal: ```bash codex plugin marketplace add firebase/agent-skills codex plugin add firebase@firebase ``` - **Option 2: Codex app** 1. Complete the following tasks one time: 1. Register through the terminal: ```bash codex plugin marketplace add firebase/agent-skills ``` 2. Fully restart the Codex app. 3. Open **Plugins**. 4. Select the Firebase marketplace/source. 5. Open **Firebase** and click **+ Install**. 2. Start a new task. 3. Type `@Firebase` to select the plugin, or ask Codex to perform a Firebase task. ### Cursor - **Option 1:** Install the plugin directly from the [Cursor Marketplace](https://cursor.com/marketplace/firebase). - **Option 2:** Run the following command in your terminal: ```bash npx skills add firebase/agent-skills --agent=cursor ``` ### Other agents Run the following command in your terminal: ```bash npx skills add firebase/agent-skills ``` > [!IMPORTANT] > **Important:** Agent skills are actively developed. To ensure your AI assistant always has the latest Firebase features, best practices, and security recommendations, be sure to regularly [update your skills](https://firebase.google.com/docs/ai-assistance/agent-skills.md.txt#update-skills). ### Update Firebase agent skills You can get all available updates and clean up out-of-date skills by running the `update` command: ### Antigravity Plugins installed from the [Antigravity Marketplace](https://antigravity.google/docs/marketplace) (or enabled during onboarding) are managed and updated automatically by Antigravity. If you installed agent skills using the `npx` command, you can get all available updates by running the `update` command: npx skills update --all ### Claude Code claude plugin marketplace update firebase ### Codex Refresh the repository snapshot: codex plugin marketplace upgrade firebase If a refreshed version is not picked up, reinstall the plugin: codex plugin remove firebase@firebase codex plugin add firebase@firebase ### Cursor npx skills update --all ### Other agents npx skills update --all ### Use Firebase agent skills AI assistants are designed to use skills automatically whenever they detect that a skill's description matches your current request. However, skills can also be manually invoked. This is often done by typing `/` in the agent chat and searching for the skill name. ## Core components of a skill Each agent skill is a specialized package centered around a `SKILL.md` definition that provides the AI assistant with the following components: - **Specialized instructions** : Detailed guidance on achieving specific tasks, such as implementing Firebase Authentication or provisioning a Cloud Firestore database. - **Best practices**: Built-in security and performance patterns to ensure your app follows Firebase recommendations from the start. - **Automation scripts**: Executable code that allows your AI agent to perform local environment setup or configuration automatically. ## Benefits to using skills Using agent skills reduces the manual effort of searching documentation while improving the efficiency of your AI interactions. ### Reduced token costs Conventional AI integrations often load massive amounts of documentation upfront, which consumes significant tokens and increases session costs. Agent skills use **progressive disclosure** to minimize this overhead: - The agent initially only "scans" brief metadata to see if a skill is relevant. - Detailed instructions and resources are only loaded when the agent determines they're necessary for your specific task. ### AI-guided implementation Instead of manually searching through documentation, you can describe your intent in natural language. Skills guide your AI assistant to perform tasks such as the following: - *Add a sign-in screen to my web app.* - *Save my to-do list items to a database.* - *Help me deploy my new web app.* For a full list of the Firebase agent skills, see [Available skills](https://firebase.google.com/docs/ai-assistance/agent-skills.md.txt#available-skills). ## Use skills alongside the Firebase MCP server Agent skills are designed to complement the [Firebase MCP server](https://firebase.google.com/docs/ai-assistance/mcp-server.md.txt): - **Firebase MCP server**: Designed for AI-assisted development workflows, enabling AI assistants to interact with your Firebase projects, resources, and data programmatically. - **Firebase agent skills** : Provide the quick instructions and recommended practices that tell an agent how to perform Firebase tasks through token-efficient progressive disclosure. They educate the agent on how to use tools like the [Firebase CLI](https://firebase.google.com/docs/cli.md.txt) and MCP server effectively. > [!NOTE] > **Note:** To get the most out of Firebase agent skills, we recommend also installing the [Firebase MCP server](https://firebase.google.com/docs/ai-assistance/mcp-server.md.txt). Having both tools installed allows the agent to use MCP tools to complete complex tasks more efficiently. ## Available skills Firebase provides a suite of skills for core products.
