Bring repository context to PR conversations
When a pull request concern comes up in a channel, let Devin explain the repository context that can help the team review it.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
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
PR discussions can fragment attention when reviewers have to leave Slack and retrace how related code works.
- Give reviewers a grounded starting point for further inspection.
- Reduce back-and-forth spent locating related code context.
- Keep PR questions moving in the channel where the team raised them.
Setup
Build it in a few focused steps.
- 1Connect Slack and Devin MCP to Notis once through the portal.
- 2Create the automation in the portal or ask Notis to create it conversationally.
- 3Write one plain-language prompt asking Devin to answer PR-related repository questions raised in channel messages.
- 4Pick the Slack channel message trigger and set the run-report channel.
- 5Test with one real PR concern and a repository that Devin can access.
