AutoGineer summary
Written by AutoGineer from the skill’s own files, not by the author
This skill provides a comprehensive framework for interacting with Google Cloud Firestore. It guides users through the lifecycle of a Firestore database, including instance provisioning, edition selection (Standard vs. Enterprise), data modeling, index management, and SDK integration across multiple platforms like Web, Android, iOS, and Flutter. It emphasizes architectural best practices, such as mandatory reference reading for SDK usage and proper security rule deployment.
What it does
- Lists and inspects existing Firestore database instances.
- Provisions new Firestore databases with specific edition and location settings.
- Provides structured guidance for data modeling using documents, collections, and subcollections.
- Facilitates SDK integration by providing platform-specific setup and initialization patterns.
- Manages database indexes and security rule deployment workflows.
- Enforces mandatory architectural checks before application code implementation.
When to use it
- When setting up a new Cloud Firestore database for an application.
- When migrating existing data or configuring database indexes.
- When integrating Firestore SDKs into Web, Android, iOS, or Flutter projects.
- When defining or updating data models for a NoSQL document-oriented structure.
- When troubleshooting or verifying database instance editions and configurations.
Advantages
- Ensures consistent database provisioning and configuration across environments.
- Provides clear paths for both Standard and Enterprise edition workflows.
- Promotes secure development practices by mandating security rule management.
- Reduces errors by requiring verification of SDK versions and architectural patterns.
Usage examples
- “List all my current Firestore databases and their editions.”
- The agent will execute the list command and provide a summary of all database IDs and their respective editions.
- “I need to set up a new Firestore database in the us-central1 region.”
- The agent will guide you through creating an Enterprise edition database in the specified location.
- “How do I query across all subcollections with the same name?”
- The agent will explain the concept of collection group queries and provide the necessary syntax for your platform.

Cloud Firestore Database and Operations
[!IMPORTANT] Security Rules Authoring (
firestore.rules) Whenever setting up a Firestore-backed app or creating/modifyingfirestore.rules, configure"firestore": { "rules": "firestore.rules" }infirebase.jsonand deployfirestore.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-authorsubagent are available: delegate authoringfirestore.rulesto thefirestore-rules-authorsubagent rather than writingfirestore.rulesdirectly in the main agent.If subagent delegation is unavailable (e.g., subagents not enabled in the IDE) OR
firestore-rules-authoris not installed: read and follow thefirestore-rules-creationskill to writefirestore.rulesdirectly.
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:listA. Instance Found
For each database found, inspect its edition and details:
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
editionisSTANDARD, follow the guides underreferences/standard/.If the
editionisENTERPRISEor native mode, follow the guides underreferences/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-creationskillSDK 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-creationskillSDK 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
