Find wiki guidance for a Slack message
Mark a message that needs documentation, and let Devin bring relevant repository wiki context into the follow-up.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Read wiki contents
View documentation about a GitHub repository. Args: repoName: GitHub repository in owner/repo format (e.g. "facebook/react")
Why this helps
Documentation follow-up often gets forgotten once a busy channel moves on to the next topic.
- Use a simple reaction to capture documentation follow-up intent.
- Bring wiki context closer to the original conversation.
- Lower the chance that a useful research question disappears in channel traffic.
Setup
Build it in a few focused steps.
- 1Connect Slack and Devin MCP to Notis once through the portal.
- 2Create an automation in the portal or ask Notis to set it up conversationally.
- 3Give Notis one instruction to use Devin's repository wiki to follow up on reacted-to messages that need documentation.
- 4Select the Slack message reaction added trigger and choose a channel for run reports.
- 5Test with one message that points to a topic documented in the repository wiki.
