User Commands
User commands allow you to trigger specific gitStream actions manually by adding comments to pull requests. These commands provide on-demand execution of automation actions without requiring changes to your .cm configuration files.
GitHub Only & v2 Action Required
User commands are only supported on GitHub and require the linear-b/gitstream-github-action@v2. This feature is not available on GitLab or Bitbucket.
