AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

The firestore-data skill provides a set of tools for interacting with Google Cloud Firestore databases. It enables developers to perform standard CRUD operations, query collections with specific filters, and explore the database hierarchy. The skill requires data to be formatted in Firestore's native JSON structure, including explicit type indicators for all fields, ensuring precise and predictable data manipulation.

What it does

Add new documents to collections with typed field definitions
Retrieve specific documents by their relative paths
Delete multiple documents using their paths
Query collections using various operators and ordering
Update existing documents with support for selective field updates via masks
List subcollections within the Firestore hierarchy

When to use it

When you need to perform programmatic CRUD operations on Firestore data
When you need to query collections based on specific field criteria
When you are exploring the structure of a Firestore database
When you need to update specific fields in a document without overwriting the entire object

Advantages

Supports granular control over document updates using update masks
Provides structured querying capabilities for complex data retrieval
Enforces explicit data typing for reliable Firestore interactions
Allows for efficient context management by toggling return data

Usage examples

“Add a new user document to the users collection with a name and age.”: The agent executes the add_documents script with the collectionPath set to 'users' and the documentData formatted with stringValue and integerValue types.
“Find all users older than 18 in the users collection.”: The agent uses query_collection with the path 'users' and a filter object specifying the field 'age', operator '>', and value 18.

Install

Download the skill as a ZIP:

Unzip it into the cross-client skills folder of your project:

mkdir -p .agents/skills && unzip firestore-data.zip -d .agents/skills

Documentation by Cline

Usage

All scripts can be executed using Node.js. Replace <param_name> and <param_value> with actual values.

Bash: node <skill_dir>/scripts/<script_name>.js '{"<param_name>": "<param_value>"}'

PowerShell: node <skill_dir>/scripts/<script_name>.js '{\"<param_name>\": \"<param_value>\"}'

Note: The scripts automatically load the environment variables from various .env files. Do not ask the user to set vars unless skill executions fails due to env var absence.

Scripts

add_documents

Adds a new document to a Firestore collection. Please follow the best practices :

Always use typed values in the documentData: Every field must be wrapped with its appropriate type indicator (e.g., {"stringValue": "text"})
Integer values can be strings in the documentData: The tool accepts integer values as strings (e.g., {"integerValue": "1500"})
Use returnData sparingly: Only set to true when you need to verify the exact data that was written
Validate data before sending: Ensure your data matches Firestore's native JSON format
Handle timestamps properly: Use RFC3339 format for timestamp strings
Base64 encode binary data: Binary data must be base64 encoded in the bytesValue field
Consider security rules: Ensure your Firestore security rules allow document creation in the target collection

Parameters

Name	Type	Description	Required	Default
collectionPath	string	The relative path of the collection where the document will be added to (e.g., 'users' or 'users/userId/posts'). Note: This is a relative path, NOT an absolute path like 'projects/{project_id}/databases/{database_id}/documents/...'	Yes
documentData	object	The document data in Firestore's native JSON format. Each field must be wrapped with a type indicator:

Strings: {"stringValue": "text"}
Integers: {"integerValue": "123"} or {"integerValue": 123}
Doubles: {"doubleValue": 123.45}
Booleans: {"booleanValue": true}
Timestamps: {"timestampValue": "2025-01-07T10:00:00Z"}
GeoPoints: {"geoPointValue": {"latitude": 34.05, "longitude": -118.24}}
Arrays: {"arrayValue": {"values": [{"stringValue": "item1"}, {"integerValue": "2"}]}}
Maps: {"mapValue": {"fields": {"key1": {"stringValue": "value1"}, "key2": {"booleanValue": true}}}}
Null: {"nullValue": null}
Bytes: {"bytesValue": "base64EncodedString"}
References: {"referenceValue": "collection/document"} | Yes | | | returnData | boolean | If set to true the output will have the data of the created document. This flag if set to false will help avoid overloading the context of the agent. | No | false |

delete_documents

Delete multiple documents from Firestore

Parameters

Name	Type	Description	Required	Default
documentPaths	array	Array of relative document paths to delete from Firestore (e.g., 'users/userId' or 'users/userId/posts/postId'). Note: These are relative paths, NOT absolute paths like 'projects/{project_id}/databases/{database_id}/documents/...'	Yes

get_documents

Gets multiple documents from Firestore by their paths

Parameters

Name	Type	Description	Required	Default
documentPaths	array	Array of relative document paths to retrieve from Firestore (e.g., 'users/userId' or 'users/userId/posts/postId'). Note: These are relative paths, NOT absolute paths like 'projects/{project_id}/databases/{database_id}/documents/...'	Yes

list_collections

List Firestore collections for a given parent path

Parameters

Name	Type	Description	Required	Default
parentPath	string	Relative parent document path to list subcollections from (e.g., 'users/userId'). If not provided, lists root collections. Note: This is a relative path, NOT an absolute path like 'projects/{project_id}/databases/{database_id}/documents/...'	No

query_collection

Retrieves one or more Firestore documents from a collection in a database in the current project by a collection with a full document path. Use this if you know the exact path of a collection and the filtering clause you would like for the document.

Parameters

Name	Type	Description	Required	Default
collectionPath	string	The relative path to the Firestore collection to query (e.g., 'users' or 'users/userId/posts'). Note: This is a relative path, NOT an absolute path like 'projects/{project_id}/databases/{database_id}/documents/...'	Yes
filters	array	Array of filter objects to apply to the query. Each filter is a JSON string with:

field: The field name to filter on
op: The operator to use ("<", "<=", ">", ">=", "==", "!=", "array-contains", "array-contains-any", "in", "not-in")
value: The value to compare against (can be string, number, boolean, or array) Example: {"field": "age", "op": ">", "value": 18} | Yes | | | orderBy | string | JSON string specifying the field and direction to order by (e.g., {"field": "name", "direction": "ASCENDING"}). Leave empty if not specified | Yes | | | limit | integer | The maximum number of documents to return | No | 100 | | analyzeQuery | boolean | If true, returns query explain metrics including execution statistics | No | false |

update_document

Updates an existing document in Firestore. Supports both full document updates and selective field updates using an update mask. Please follow the best practices:

Use update masks for precision: When you only need to update specific fields, use the updateMask parameter to avoid unintended changes
Always use typed values in the documentData: Every field must be wrapped with its appropriate type indicator (e.g., {"stringValue": "text"})
Delete fields using update mask: To delete fields, include them in the updateMask but omit them from documentData
Integer values can be strings: The skill accepts integer values as strings (e.g., {"integerValue": "1500"})
Use returnData sparingly: Only set to true when you need to verify the exact data after the update
Handle timestamps properly: Use RFC3339 format for timestamp strings
Consider security rules: Ensure your Firestore security rules allow document updates

Parameters

Name	Type	Description	Required	Default
documentPath	string	The relative path of the document which needs to be updated (e.g., 'users/userId' or 'users/userId/posts/postId'). Note: This is a relative path, NOT an absolute path like 'projects/{project_id}/databases/{database_id}/documents/...'	Yes
documentData	object	The document data in Firestore's native JSON format. Each field must be wrapped with a type indicator:

Strings: {"stringValue": "text"}
Integers: {"integerValue": "123"} or {"integerValue": 123}
Doubles: {"doubleValue": 123.45}
Booleans: {"booleanValue": true}

Maps: {"mapValue": {"fields": {"key1": {"stringValue": "value1"}, "key2": {"booleanValue": true}}}}
Null: {"nullValue": null}
Bytes: {"bytesValue": "base64EncodedString"}
References: {"referenceValue": "collection/document"} | Yes | | | updateMask | array | The selective fields to update. If not provided, all fields in documentData will be updated. When provided, only the specified fields will be updated. Fields referenced in the mask but not present in documentData will be deleted from the document | No | | | returnData | boolean | If set to true the output will have the data of the updated document. This flag if set to false will help avoid overloading the context of the agent. | No | false |

      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
