Firebase Firestore Agent Skill

Cloud Firestore Database and Operations

Before setting up dependencies, writing data models, or configuring security

rules, you MUST always identify the Firestore instance edition.

1. Instance Selection and Edition Detection

Run the following command to list current Firestore databases:

bash npx -y firebase-tools@latest firestore:databases:list

A. Instance Found

• For each database found, inspect its edition and details:

bash npx -y firebase-tools@latest firestore:databases:get <database-id>

• Ask the user which database instance they wish to target or if they would

prefer to create a new instance.

• Once the target instance is established:
• If the edition is STANDARD, follow the guides under

references/standard/.

• If the edition is ENTERPRISE or native mode, follow the guides

under references/enterprise/.

B. No Instance Found (or New Requested)

If no databases exist or the user requests a new one, default to provisioning an

Enterprise edition database and ask the user what location to use. Run

npx -y firebase-tools@latest firestore:locations to get the list of options.

Suggest colocating with other resources if applicable.

Once the location is determined, create the database:

bash npx -y firebase-tools@latest firestore:databases:create <database-id> --edition="enterprise" --location="<selected-location>"

Proceed with using the guides under references/enterprise/.
