-When an [automation](/automations) posts a [Slack notification](/automations/manage#slack-notifications) about a pull request it opened, reply in that thread and mention `@mintlify` to continue the work.

+When a code change automation opens a documentation pull request, it posts a comment on the triggering code pull request linking to the docs pull request it created, and assigns a reviewer by trying the code pull request's author and committers in order until one accepts.
 
 ## Manage automations
 
-Ask the agent to create, configure, or run [automations](/automations). The agent can perform the same actions as you on the [Automations](https://app.mintlify.com/products/automations) page of your dashboard.
+The Slack agent and [Automations](/automations) both use the Mintlify agent. Ask the agent to create, configure, run, or troubleshoot any automation. It can perform every action available to you on the [Automations](https://app.mintlify.com/products/automations) page of your dashboard.
 
 Example prompts:
 
 - "Create an automation that drafts a changelog entry every time we merge to main."
 - "Set up an automation that updates the docs whenever a Jira issue closes."
 - "Turn off the weekly changelog automation."
-- "Run the automation that reviews assistant conversations right now."
+- "Run the code change automation on PR #123."
+- "Review the last month of merges and update the changelog."
 
 You can also ask the agent about automation activity, such as recent runs, failures, or credit use.
 
 - "How can I make my automations more credit efficient?"
 - "Why did the last run of the code change automation fail?"
 
+### Trigger automations from Slack messages
+
+You can configure a custom automation to run when someone posts a top-level message in a chosen Slack channel. The agent reads each message, decides whether it warrants a documentation update, and opens a pull request when it does. Set this up when you create or edit the automation on the [Automations](https://app.mintlify.com/products/automations) page.
+
+The `mintlify` app must be a member of the channel you choose. Invite it with `/invite @mintlify` before saving the automation.
+
 ## Reference other repositories
 
 The agent can read source code from any repository connected through the [GitHub App](/deploy/github) or [GitLab integration](/deploy/gitlab), even if it isn't your documentation repository. This lets the agent build deeper context to guide documentation updates.

+## Use the agent in the Slack sidepanel
+
+Chat with `@mintlify` in the Slack side panel to ask questions or request documentation updates without posting in a channel. The sidepanel agent behaves like the Slack agent: same permissions, same tools, and the same review process for any changes it makes.

 ## Best practices
 
 - **Be specific**: Tell the agent exactly what you want to know or what you want changed and where.
