Follow up on architecture discussions with code context
Mark the architecture message that needs more context and let Devin help the team understand how the repository currently works.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Ask question
Ask any question about a GitHub repository and get an AI-powered, context-grounded response. Args: repoName: GitHub repository or list of repositories (max 10) in owner/repo format question: The question to ask about the repository
Why this helps
Architecture follow-up gets deferred when nobody has an uninterrupted block to explore implementation details.
- Capture a follow-up signal directly on the relevant message.
- Connect architecture discussion to current repository context.
- Reduce the chance that an open technical question is forgotten.
Setup
Build it in a few focused steps.
- 1Connect Slack and Devin MCP to Notis once through the portal.
- 2Create an automation through the portal or by asking Notis conversationally.
- 3Give Notis one instruction asking Devin to explain implementation context for architecture messages marked with the chosen reaction.
- 4Choose the Slack message reaction added trigger and a channel for run reports.
- 5Test by reacting to one real architecture message.
Questions about this workflow
Can I use this for only one reaction?
