Firebase Basics

A guide skill that helps you apply the correct setup order, current commands, and security patterns when working on a web or mobile project that uses Firebase products. To prevent falling back on old/deprecated patterns, it verifies NPM and installs/updates the firebase/agent-skills package before starting work; it then signs in via the Firebase CLI and sets the active project context.

When to use it? When adding Firebase to an app, creating a new Firebase project, initializing Firestore/Auth/Hosting/Functions, writing security rules, or performing Firebase operations via the CLI/MCP server.

What it produces? A step-by-step setup and integration guide (Markdown): a prerequisite verification table, the actual CLI commands to run (bash), a modular client SDK example (TypeScript), Firestore security rules, and recommended next steps. The output delivers a secure and up-to-date Firebase setup that preserves the order: prerequisites → project context → client SDK → security → deploy.

Reference areas it covers: core concepts, CLI usage, client library usage, MCP server, IaC, and IAM/security. When deeper product knowledge is needed, it points you to the Developer Knowledge MCP search_documents tool.
