Why this helps
A decision is easy to find later but harder to understand when its surrounding discussion is scattered.
- Recover stated rationale from nearby context.
- Highlight implications or dependencies.
- Make decisions easier to revisit.
Setup
Build it in a few focused steps.
- 1Connect Slack and DeepSeek to Notis once in the portal.
- 2Create an automation or ask Notis to explain reacted-to Slack decisions.
- 3Use one instruction asking DeepSeek to summarize the decision, stated rationale, implications, and any missing context.
- 4Pick the Slack reaction added trigger and choose a channel for run reports.
- 5Test by reacting to a real message that records a decision.
Questions about this workflow
Can it recover context from an entire channel?
The response depends on the message and context available to the automation. Ask DeepSeek to state when the supplied context is incomplete.
Can the reaction be limited to a decision marker?
The trigger can optionally filter by emoji name and channel.
