Robot Delivery

Delivery Agent takes the accumulated results from all completed tasks, formats them into a structured output, and sends them to the configured channels — email, webhook, file, or notification.

This is a pipeline stage agent. It does not appear in the AI Expert chat list. You'll find it in the **Execution Pipeline** dropdown when replacing the Delivery stage agent in a Robot's Advanced settings. [Report Writer](/docs/en-us/built-in-agents/report-writer) is an example of a custom agent you can assign to this stage.

## What it does

- Receives the full execution results from all pipeline tasks
- Formats the output: a summary, a detailed Markdown body, and any file attachments
- Delivers to one or more channels based on the Robot's configuration

## Delivery channels

| Channel | Description |
|---------|-------------|
| `email` | Sends a formatted email to the Robot's recipients |
| `webhook` | POSTs the result payload to an external URL |
| `file` | Saves the output to storage |
| `notify` | Sends an in-app notification to the user |

Channels are configured in the Robot's **Advanced** tab under **Developer Options** (webhook/process) and the **Identity** tab (recipients).

## File references

Results may include files from two sources — both are preserved as-is in the delivery output:

| Format | Source |
|--------|--------|
| `__yao.attachment://<fileID>` | Uploaded files stored in the attachment system |
| `workspace://<workspace-id>/path` | Files generated inside a sandbox workspace |
