Slack

How Dispatch reads channels and threads in your Slack workspace and posts on your behalf.

To connect Slack, open the in-app Connections settings.

Slack lets Dispatch operate inside your team's messaging. The agent can list and read channels you belong to, follow threads, post messages, and download files shared in channels.

OAuth scopes

Dispatch requests the Slack scopes it needs and no more. The in-app connect screen shows the current scope request before you authorize.

Read capabilities

  • List channels the Slack app is in, including public channels, private channels, and direct-message conversations.
  • Read recent message history in a channel or DM.
  • Read messages in a thread.
  • Download files attached to messages.

Write capabilities

Posting is annotated external-write and passes through the permission gate.

  • Post a message in a channel or in a thread.

What automations can use

Slack is a chat origin, not a triggered-automation source. Messages a user sends to Dispatch through Slack create chat-origin agent runs in the user's account, similar to Telegram. Slack does not currently expose event-based automation triggers (no SLACK_MESSAGE trigger type).

  • Scheduled actions that read or post to Slack are supported (for example, "every Friday afternoon, post a wrap-up to #team").

Limits and behavior

  • Posts are gated. Posting in a public channel is consequential; post tools carry an external-write risk annotation and route through the permission gate. The gate consults your policy on every post once the permissionAgent enforcement flag is on for your org; while the flag is off the gate emits telemetry and lets the post through. Rules like "always ask before posting to #leadership" go in /preferences/permissions.md.
  • Identity. Slack OAuth uses bot scopes, so posts are attributed to the Dispatch Slack app rather than your user account.
  • Per-workspace. Each connected Slack workspace is a separate connection.
  • Search, edit, delete not exposed. The connector reads channel, DM, and thread history; message search, edit, and delete are not in the current tool set.
