Capture decisions without rereading the whole thread
When a team decision appears in Slack, get a compact brief that makes the outcome and follow-up easier to act on.
Trigger

Action

Why this helps
Decisions buried in fast-moving channel conversations are easy to lose between tasks.
- Pulls the stated decision into a short, readable summary.
- Highlights owners and follow-up only when the message provides them.
- Reduces the need to revisit a long conversation.
Setup
Build it in a few focused steps.
- 1Connect Slack and Anthropic administrator to Notis once in the portal.
- 2Create an automation in the portal and give it a name.
- 3Use one prompt: When a Slack channel message reports a decision, create a concise brief with the decision, any stated owner, and the next step; do not guess missing details.
- 4Pick the Slack Channel Message Received trigger, choose a channel for run reports, and test with one real decision message.
