Automate PR Review Requests from Linear Issues to GitHub

Engineering teams lose time manually creating GitHub pull requests and linking them back to Linear issues. This workflow reads in-progress Linear issues, checks for associated GitHub branches or PRs, and posts review request reminders to Slack when PRs have been open without review for too long.

How the workflow runs

The scenario uses specific integration tools at each step, while Metorial keeps access scoped and visible.

  1. 1

    Find in-progress Linear issues

    Search Linear for issues in the In Progress or In Review state that have been open beyond the expected cycle time.

    • linear:search_issues
  2. 2

    Retrieve issue details and branch context

    Fetch full details for each flagged Linear issue to identify the associated branch name and assignee.

    • linear:get_issue
  3. 3

    List open pull requests

    Query GitHub for open pull requests matching the branch names from the Linear issues.

    • github:list_pull_requests
  4. 4

    Check review status

    Retrieve PR details to determine if reviews have been requested, submitted, or if the PR is blocked.

    • github:get_issue
  5. 5

    Send review reminder to Slack

    Post a message to the engineering Slack channel listing PRs awaiting review with links, author names, and time open.

    • slack:send_message
  6. 6

    Update Linear issue status

    Update the Linear issue state to reflect any PRs that have already been merged or closed since the last check.

    • linear:update_issue
