Spot the missing detail before work stalls
Convert a vague channel request into a focused question that makes the next action clearer.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
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
Ambiguous asks force repeated rereading and back-and-forth before anyone can start.
- Calls attention to details the request leaves open.
- Creates one concise, neutral question to resolve uncertainty.
- Helps reduce avoidable follow-up loops.
Setup
Build it in a few focused steps.
- 1Connect Slack and Anthropic administrator to Notis once through the portal.
- 2Create a named automation in the portal or tell Notis what outcome you want in plain language.
- 3In one instruction, ask Anthropic to identify ambiguity in each Slack channel request and draft one respectful clarification question without sending it or inventing context.
- 4Choose Channel Message Received as the trigger, select a run-report channel, and test on one real ambiguous request.
Questions about this workflow
Will the clarification be posted to Slack automatically?
The action generates assistant text; the prompt can ask for a draft and should not imply it sends a Slack reply.
What if the request is already clear?
The instruction can ask for a brief note that no clarification appears necessary.
