# Firebase

Use this as the single executable router for Firebase work.

## Routing

- Start with project and CLI context; use npx firebase-tools where the folded references require it.
- Route product-specific work to Auth, Firestore, Hosting, Data Connect, AI Logic, App Hosting, Crashlytics, or Remote Config references.
- Security-sensitive work loads Security Rules guidance before writing rules or data access code.

## Reference Loading

Load one folded reference at a time. Prefer the most specific reference that matches the user's named service, framework, command, or error. If no folded reference matches, use the router guidance here and verify with primary docs or local project state.

These former standalone skills are bundled here as references to keep the runtime list compact. Load only the reference that matches the user's exact product, framework, or failure mode.
