No check matched anything in these tool definitions.


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `gocanvas_create_dispatch`

- The name "gocanvas_create_dispatch" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
WRITE: creates a dispatch, a job that appears on the assignee's mobile device (immediate_dispatch is sent at once, with a push notification when send_notification is true; scheduled_dispatch needs scheduled_at and scheduled_end). Responses pre-fill the assignee's form (entry ids from gocanvas_get_form). Without assignee_id the dispatch stays unassigned. Not idempotent: calling twice creates two dispatches. Media fields cannot be pre-filled.
```

### `gocanvas_mark_dispatch_received`

- The name "gocanvas_mark_dispatch_received" says "mark": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
WRITE: acknowledges a dispatch (status becomes received). Only works for a dispatch in the assigned state that is assigned to the connected user; repeating it is refused by GoCanvas.
