Trigger

Action

Why this helps
A task can quietly wait on another person or decision without a clear follow-up owner.
- Highlights stated prerequisites and handoffs.
- Shows when a dependency lacks an explicit owner or next check.
- Helps focus follow-up on the point that is holding work.
Setup
Build it in a few focused steps.
- 1Connect Slack and Anthropic administrator once via the portal.
- 2Create a named automation in the portal.
- 3Write one prompt asking Anthropic to identify dependencies and handoffs in each relevant channel message, including stated owners and unresolved ownership gaps.
- 4Select Channel Message Received, choose a run-report channel, and test on a real message that mentions something pending.
Questions about this workflow
Does it assign owners to open dependencies?
No. It reports stated ownership and identifies gaps without assigning people.
Can it tell a dependency is blocking work?
It can report explicit waiting or blocking language and label other concerns as possible.
