Open Tasks → Pull requests and select a GitHub PR. Mains fetches its current details from GitHub rather than importing it as a synced issue.

​
Before you begin

Connect GitHub with access to the repository. Your account and token need permission for the actions you want to take. The PR inbox uses the stored connection token. It does not need the GitHub CLI used for creating a PR from your workspace.

​
Inspect the PR

Read the description, author, reviewers, comments, checks, and merge status. Browse the file-by-file diff and inspect existing review threads. The default inbox scope follows the repositories selected on the GitHub connection. You can change the search filters to find another PR you can access.

​
Comment and resolve

You can add a general comment, start a thread on a diff line, reply to a thread, and resolve it. These actions publish to GitHub. Review the text before submitting. They are separate from workspace diff comments, which are attached to a local agent message.

​
Merge or mark ready

For a draft, choose Mark ready when it is ready for review. For an eligible PR, choose Merge, Squash, or Rebase. GitHub’s repository permissions, checks, and branch rules still apply. A blocked merge remains blocked and Mains reports the provider’s error.

​
Current support

The live PR inbox supports GitHub. GitLab issue sync does not provide a GitLab merge-request review interface.
