Cloud Firestore Database and Operations

[!IMPORTANT] Security Rules Authoring (`firestore.rules`) Whenever your task requires creating, authoring, or modifying firestore.rules: - 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.

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:

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

A. Instance Found

1. For each database found, inspect its edition and details:

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

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

prefer to create a new instance.

1. 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:

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

Proceed with using the guides under references/enterprise/.

2. Specialized Guides

Based on the identified or created instance edition, open and read the corresponding reference guides:

Standard Edition (references/standard/)

• Provisioning: Read provisioning.md
• Security Rules: See the firestore-rules-creation skill
• SDK Usage: Read web_sdk_usage.md,

android_sdk_usage.md, ios_setup.md, or flutter_setup.md

• Indexes: Read indexes.md

Enterprise Edition / Native Mode (references/enterprise/)

• Provisioning: Read

provisioning.md

• Data Model: Read data_model.md

• Security Rules: See the firestore-rules-creation skill

• SDK Usage:

[!CRITICAL] Mandatory Reference Reading Before writing or modifying any application code for Firestore Enterprise Edition, you MUST read at least one of the relevant reference documents below for the target platform/language to understand specific architectural requirements and pipeline initialization patterns.

Read web_sdk_usage.md, python_sdk_usage.md, android_sdk_usage.md, ios_setup.md, or flutter_setup.md

• Indexes: Read indexes.md
