Get a quick read on what a new direct message asks for, how time-sensitive it sounds, and what response may be needed.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Action
Create Message
Tool to create a new message completion. use when you need to generate assistant text given a conversation history.
Why this helps
Several incoming DMs can compete for attention without making their relative urgency clear.
- Summarizes the message request in plain language.
- Labels urgency based on explicit cues in the DM.
- Surfaces a likely next response without sending it.
Setup
Build it in a few focused steps.
- 1Connect Slack and Anthropic administrator to Notis once in the portal.
- 2Create a named automation, either in the portal or by describing it to Notis.
- 3Use a single instruction asking Anthropic to summarize each new DM, assess urgency from its wording, and suggest a response direction without replying or assuming a deadline.
- 4Pick Direct Message Received, choose a run-report channel, and test with one real DM.
Questions about this workflow
Will it send a reply to the person?
No. The instruction asks for a suggested response direction; the action creates assistant text.
How should it handle urgency it cannot determine?
Ask it to label urgency as unclear when the DM gives no reliable timing cues.
