const result = await deepline.tools.execute(
  'slack_upload_file',
  {
    "channel_id": "channel_123",
    "channels": "example",
    "filename": "example"
  },
);

console.log(result.toolResponse.raw);

Example response

The static output schema lacks the details for a reliable example. Use deepline describe slack_upload_file --json for the complete live contract.

Input reference

Slack filesUploadV2-compatible external upload. Use Slack file/content fields. Deepline materializes Dataset Handles into bounded CSV attachments with row-safe truncation and no server filesystem access. Requires files:write.

Name	Type	Required	Default	Details
`payload.channel_id`	`string`	No	—	Minimum length: 1.
`payload.channels`	`string`	No	—	Comma-separated Slack channel or user IDs. This maps to files.completeUploadExternal. do not combine with thread_ts. Minimum length: 1.
`payload.filename`	`string`	No	—	Slack filename, including its extension. Minimum length: 1. Maximum length: 255.
`payload.file`	`unknown`	No	—	Slack file value. Provide a Dataset Handle or a { run_id, path?, dataset_id? } selector to materialize a completed Deepline dataset as a bounded CSV. In a Play, pass the handle directly. Deepline pages rows, retains complete rows within 50,000 rows, 500 columns, and 25 MiB, and reports omissions in meta.file_transport. Any other JSON value is serialized as a file. Deepline never reads a server filesystem path.
`payload.content`	`string`	No	—	Slack text file contents. Use this for CSV, HTML, JSON, Markdown, or plain text. Exactly one of content or file is required. Maximum length: 37748736.

`payload.snippet_type`	`string`	No	—	Slack snippet syntax identifier, such as python. Minimum length: 1. Maximum length: 255.
`payload.file_uploads`	`array`	No	—	Slack filesUploadV2 batch entries. May be combined with a top-level file or content, as in Slack’s Web API client. Minimum items: 1. Maximum items: 10.
`payload.initial_comment`	`string`	No	—	Optional text introducing the shared files. Minimum length: 1.
`payload.blocks`	`array`	No	—	Maximum items: 50.
`payload.thread_ts`	`string`	No	—	Parent message timestamp. Shares the files as a thread reply. Use only with the parent message timestamp. Minimum length: 1.
`payload.username`	`string`	No	—	Optional bot display name for the file share. Requires chat:write.customize. Minimum length: 1.
`payload.icon_url`	`string`	No	—	Optional bot icon URL for the file share. Requires chat:write.customize. Format: `uri`. Minimum length: 1.
