Why this helps
Capacity constraints can remain implicit until commitments pile up or deadlines slip.
- Highlights capacity limits stated in the message.
- Separates constraints from inferred interpretations.
- Makes tradeoffs easier to discuss before adding work.
Setup

- 2Create an automation with a clear name.
- 3Use one prompt asking Anthropic to summarize explicit capacity constraints and tradeoffs in relevant channel messages, labeling any interpretation as uncertain.
- 4Select Channel Message Received, pick a report channel, and test with one real message that discusses bandwidth.
