## Iron Law
**NEVER use the naked `firebase` binary — always `npx -y firebase-tools@latest <cmd>`.**
This guarantees the latest CLI version is used without polluting global node_modules.
Every command in this skill prepends `npx -y firebase-tools@latest`.
## Project Context
Check the project's `CLAUDE.md` to understand which Firebase services are in use and any
project-specific constraints (e.g. which services are intentionally NOT used, whether
Firestore is used as a canonical store or a status bus only, etc.).
Firebase project ID should be stored in an environment variable (e.g. `FIREBASE_PROJECT_ID`)
— never hardcoded.
# Prerequisites
1. **Local Environment Setup:**
```bash
npx -y firebase-tools@latest --version
```
Read [references/local-env-setup.md](references/local-env-setup.md) for full setup.
2. **Authentication:**
```bash
npx -y firebase-tools@latest login
# Headless / remote shell:
npx -y firebase-tools@latest login --no-localhost
```
3. **Active Project:**
```bash
npx -y firebase-tools@latest use
# Set project from env var (preferred):
npx -y firebase-tools@latest use --add ${FIREBASE_PROJECT_ID}
```
# Firebase Usage Principles
1. **npx always:** `npx -y firebase-tools@latest <cmd>` — never bare `firebase`
2. **Consult Firebase MCP first:** Use `developerknowledge_search_documents` before
falling back to web search or memory
3. **Use Firebase MCP tools for remote API calls:** Crashlytics, Firestore queries,
project management — always MCP, never manual REST calls
4. **Emulator for local dev:** Set `FIREBASE_AUTH_EMULATOR_HOST` and related emulator
environment variables — without them, Admin SDK calls hit production Firebase with
dev tokens
