Firebase Firestore

This handles Cloud Firestore operations from detection through deployment, and it's opinionated in the right way. It forces you to identify whether you're on Standard or Enterprise edition before doing anything else, then routes you to edition-specific guides for security rules, SDK setup, and indexing. Works with Firebase CLI under the hood but doesn't require a global install. The automatic defaulting to Enterprise for new databases is a smart choice given Google's direction. If you're doing any Firestore work beyond trivial reads, the structured approach to data modeling and security rules will save you from the usual Firebase gotchas around permissions and query performance.

Cloud Firestore Database and Operations

[!IMPORTANT] Security Rules Authoring (firestore.rules) Whenever setting up a Firestore-backed app or creating/modifying firestore.rules, configure "firestore": { "rules": "firestore.rules" } in firebase.json and deploy firestore.rules (npx -y firebase-tools@latest deploy --only firestore:rules), even if server routes use the Admin SDK:

If subagent delegation AND the firestore-rules-author subagent are available: delegate authoring firestore.rules to the firestore-rules-author subagent rather than writing firestore.rules directly in the main agent.

If subagent delegation is unavailable (e.g., subagents not enabled in the IDE) OR firestore-rules-author is not installed: read and follow the firestore-rules-creation skill to write firestore.rules directly.
