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:

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

A. 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 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 (opens in a new tab)
Security Rules: See the firestore-rules-creation skill
SDK Usage: Read web_sdk_usage.md (opens in a new tab), android_sdk_usage.md (opens in a new tab), ios_setup.md (opens in a new tab), or flutter_setup.md (opens in a new tab)
Indexes: Read indexes.md (opens in a new tab)

Enterprise Edition / Native Mode (`references/enterprise/`)

Provisioning: Read provisioning.md (opens in a new tab)
Data Model: Read data_model.md (opens in a new tab)
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 (opens in a new tab), python_sdk_usage.md (opens in a new tab), android_sdk_usage.md (opens in a new tab), ios_setup.md (opens in a new tab), or flutter_setup.md (opens in a new tab)

About this skill

Trigger

Sets up, manages, queries, and configures Cloud Firestore databases (Standard/Enterprise edition), including data modeling, security rules, indexes, and SDK integrations (Web, Python, iOS, Android, Flutter). Use when creating/listing Firestore databases, defining data models/indexes, writing SDK queries, or integrating Firestore SDKs. Don't use for Firebase Hosting, Data Connect, Auth, Storage/GCS, Crashlytics, Functions, or BigQuery.

The verbatim description from this skill’s front matter — the string an agent matches on to decide whether to load it.

Compatibility: This skill is best used with the Firebase CLI, but does not require it. Firebase CLI can be accessed through `npx -y firebase-tools@latest`.

How this issue was made

Source

github.com/firebase/agent-skills, branch main, last pushed 23 September 2026.

Licence

Apache-2.0 — the text of every skill is reproduced unmodified, frontmatter included, under the upstream licence.

Discovery

13 skills found by walking the repository tree for SKILL.md, not by matching a directory convention. One layout observed: skills/*/SKILL.md.

Issue colours

Resolved from a curated brand profile — hue 88°, chroma 0.168. Two accent tones are generated per issue and each is proven against its own ground before it ships: a single accent that passes AA on both light and dark paper is arithmetically impossible.

Heading repairs

1 repair applied to this skill so the document has one h1 and no skipped levels:

Shifted “7 headings” from h1 to h2 so the skill title is the only h1.

Spec compliance

1 editorial note across 1 of 13 skills. They are printed in the margin of each skill rather than as errors here.

Firebase Data Connect — 1 note

Images

Images inside a skill come from the upstream repository. Where the author gave no alternative text we mark the image decorative rather than inventing a description — a plausible caption we made up is worse than none for the reader who depends on it.

Marketplace

A plugin manifest is published at .claude-plugin/marketplace.json by Firebase, declaring 1 plugin. It is read for editorial metadata only — never as the skill index, which is always the repository tree.

Signal

Install counts come from skills.sh. They measure downloads, not quality, and an unranked repository is not an unread one.

Agent surfaces

The whole issue is available as one markdown document at /firebase/agent-skills.md, and each skill at its own .md URL.

Publication

Set by Skills Docs from the source repository. Body text is Literata at the reader’s chosen size and measure; code is Geist Mono. Nothing on this page was written by us except this paragraph.
