# Google Chat

## Freshness
Last updated: `2026-06-29`.

If the current date is more than 7 days after the last updated date, reinstall this skill from skills.sh or ClawHub before relying on endpoints, schemas, setup steps, or examples.

## What This Tool Does
Bridge your agent to your Google Chat spaces—post updates, keep threads moving, and turn routine teamwork into quick, automated nudges that keep everyone in sync. Supports reactions, direct messaging, and posting and reading in spaces. All actions take place as the connected user.

## Product Instructions
### Google Chat

Read spaces, list and search messages, send messages, react to messages, and move attachments between Google Chat and AgentPMT File Manager.

This tool uses the existing AgentPMT Google OAuth scopes only:

- `chat.spaces.readonly`
- `chat.messages`
- `chat.messages.reactions`

It does not manage members or users, does not create/update/delete spaces, does not use admin access, and does not expose custom emoji actions. Member listing requires `chat.memberships.readonly` or `chat.memberships`, which this connection does not currently have.

#### Parameters

- `action` (string, required): Action to perform. Default: `get_instructions`
- `space` (string): Space name or ID, such as `"spaces/AAA"` or `"AAA"`
- `message_name` (string): Message resource name, or short message ID when `space` is provided
- `reaction_name` (string): Reaction resource name, or short reaction ID when `message_name` is provided
- `attachment_name` (string): Attachment resource name, short attachment ID, or attachment `contentName` when `message_name` is provided
- `media_resource_name` (string): Direct `attachmentDataRef.resourceName` for Chat media download
- `user_name` (string): User resource name, such as `"users/123"`
- `query` (string): Search query for space/message/attachment search actions
- `text` (string): Message text
- `cards_v2` (array): Cards v2 payload
- `thread_name` (string): Existing Chat thread resource name
- `thread_key` (string): Thread key for message creation
- `message_reply_option` (string): `REPLY_MESSAGE_FALLBACK_TO_NEW_THREAD` or `REPLY_MESSAGE_OR_FAIL`
- `message_request_id` (string): Google Chat `requestId` for idempotent message creation
- `message_id` (string): Client-assigned Google Chat message ID
- `notification_type` (string): `NOTIFICATION_TYPE_NONE`, `NOTIFICATION_TYPE_FORCE_NOTIFY`, or `NOTIFICATION_TYPE_SILENT`
- `page_size` (integer, default 50): Max results per page. Reactions max is 200.
- `page_token` (string): Pagination token
- `filter` (string): Google Chat filter query
- `order_by` (string): Sort order
- `show_deleted` (boolean, default false): Include deleted messages in message list/search
- `max_results` (integer, default 25): Max client-side search matches
- `scan_limit` (integer, default 500): Max messages scanned by bounded client-side search
- `case_sensitive` (boolean, default false): Use case-sensitive client-side search
- `search_fields` (array): Fields searched by `search_messages`: `text`, `formatted_text`, `argument_text`, `sender`, `attachment_name`
- `emoji_unicode` (string): Unicode emoji for `add_reaction`
- `force` (boolean, default false): For `delete_message`, also delete threaded replies
- `file_ids` (array): AgentPMT File Manager file IDs to upload and attach to `create_message` or `reply_message`
- `source_file_id` (string): AgentPMT File Manager file ID for `upload_attachment`
- `filename` (string): Optional upload filename override
- `content_type` (string): Optional upload MIME type override
- `max_upload_bytes` (integer, default 26214400): Max File Manager bytes uploaded to Chat
- `max_bytes` (integer, default 26214400): Max Chat attachment bytes downloaded
- `output_filename` (string): File Manager filename for downloaded attachment
- `expiration_days` (integer, default 7): Stored download expiration, 1-7 days

#### Sorting

`list_messages` sends `order_by: "create_time DESC"` by default, so messages are newest first. Send `order_by: "create_time ASC"` for oldest first.

Google also accepts legacy camel-case sort aliases from this tool:

```json
{"action":"list_messages","space":"spaces/AAA","order_by":"createTime DESC"}
```

The tool normalizes that to official Google Chat syntax.

#### Search

`search_spaces` is Google server-side search. Non-admin Google Chat search needs a display-name query for useful results:

```json
{"action":"search_spaces","query":"display_name:\"Launch\"","order_by":"relevance DESC"}
```

`search_messages` and `search_attachments` are bounded client-side searches within one space. They page through accessible messages using `list_messages`, scan up to `scan_limit`, and return `scan_limit_reached` when the scan stopped before the space was exhausted. These are not global Google-side full-text search endpoints.

#### File Upload

Preferred path: attach File Manager files directly when creating or replying to a message.

```json
{
  "action": "create_message",
  "space": "spaces/AAA",
  "text": "Attached is the latest report.",
  "file_ids": ["file-manager-id-1"]
}
```

Advanced path: use `upload_attachment` to stage a File Manager file in Chat and return an `attachment_data_ref`.

```json
{"action":"upload_attachment","space":"spaces/AAA","source_file_id":"file-manager-id-1"}
```

File uploads require normal authenticated budget context. Admin bypass cannot read budget-scoped File Manager files.

#### File Download

List attachments on a message:

```json
{"action":"list_message_attachments","message_name":"spaces/AAA/messages/BBB"}
```

Download an attachment into AgentPMT File Manager:

```json
{
  "action": "download_attachment_to_storage",
  "message_name": "spaces/AAA/messages/BBB",
  "attachment_name": "spaces/AAA/messages/BBB/attachments/ATT",
  "output_filename": "report.pdf"
}
```

If you already have `attachment.attachmentDataRef.resourceName`, you can download directly:

```json
{
  "action": "download_attachment_to_storage",
  "media_resource_name": "spaces/AAA/messages/BBB/attachments/ATT/media",
  "output_filename": "report.pdf"
}
```

`get_attachment` reads the parent message and finds the attachment in message data. It does not call the bot-only `spaces.messages.attachments.get` endpoint.

## Live Schema And Examples
Use the compact schema above for ordinary calls. Before a new production integration, or whenever parameters, enum values, nested objects, outputs, or examples are unclear, fetch live details first.

- Exact schema: call `agentpmt-tool-search-and-execution` with `action: "get_schema"`, and `tool_id: "google-chat"`.
- Detailed examples: call `agentpmt-tool-search-and-execution` with `action: "get_instructions"` and `tool_id: "google-chat"`, or call this product with `action: "get_instructions"` when the product tool is already selected.
- Treat returned live schema and instructions as more specific than this generated summary.

MCP schema lookup through the main AgentPMT MCP server:

```json
{
  "method": "tools/call",
  "params": {
    "name": "AgentPMT-Tool-Search-and-Execution",
    "arguments": {
      "action": "get_schema",
      "tool_id": "google-chat"
    }
  }
}
```

For live examples, keep the same MCP tool and use these arguments:

```json
{
  "action": "get_instructions",
  "tool_id": "google-chat"
}
```

Authenticated AgentPMT REST schema lookup body:

```json
{
  "name": "agentpmt-tool-search-and-execution",
  "parameters": {
    "action": "get_schema",
    "tool_id": "google-chat"
  }
}
```

Authenticated AgentPMT REST live examples body:

Use the exact tool name returned by `tools/list`; the name above is the expected readable form.

Authenticated AgentPMT REST call body:

```json
{
  "name": "google-chat",
  "parameters": {
    "action": "add_reaction",
    "emoji_unicode": "example emoji unicode",
    "message_name": "example message name",
    "space": "example space"
  }
}
```

Use the setup skill for the account connection details before making REST calls.

## Response Handling
- Treat the returned JSON as the source of truth for this tool call.
- If the response includes warnings or correction targets, apply them before retrying.
- If the response includes a `passed` or success-style boolean, use it as the workflow gate.
- If validation fails or the response shape is unclear, call `get_schema` or `get_instructions` before retrying.
- If `add_reaction` fails, preserve the request parameters and retry only after fixing schema, auth, or payment errors.

## Security
- Do not place account secrets, wallet private keys, mnemonics, signatures, or payment headers in prompts or logs.
- Keep tool inputs scoped to the minimum content needed for the task.
- Use the setup skills for credential handling; this product skill only defines product-specific behavior.
