| `/child_epic <epic>` | | | ✓ | Add child epic to `<epic>`. The `<epic>` value should be in the format of `&epic`, `group&epic`, or a URL to an epic ([introduced in GitLab 12.0](https://gitlab.com/gitlab-org/gitlab/-/issues/7330)). **(ULTIMATE)** |
| `/clone <path/to/project> [--with_notes]`| ✓ | | | Clone the issue to given project, or the current one if no arguments are given ([introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/9421) in GitLab 13.7). Copies as much data as possible as long as the target project contains equivalent labels, milestones, and so on. Does not copy comments or system notes unless `--with_notes` is provided as an argument. |
| `/epic <epic>` | ✓ | | | Add to epic `<epic>`. The `<epic>` value should be in the format of `&epic`, `group&epic`, or a URL to an epic. **(PREMIUM)** |
| `/estimate <<W>w <DD>d <hh>h <mm>m>` | ✓ | ✓ | | Set time estimate. For example, `/estimate 1w 3d 2h 14m`. |
| `/iteration *iteration:"iteration name"` | ✓ | | | Set iteration. For example, to set the `Late in July` iteration: `/iteration *iteration:"Late in July"` ([introduced in GitLab 13.1](https://gitlab.com/gitlab-org/gitlab/-/issues/196795)). **(STARTER)** |
| `/label ~label1 ~label2` | ✓ | ✓ | ✓ | Add one or more labels. Label names can also start without a tilde (`~`), but mixed syntax is not supported. |
| `/merge` | | ✓ | | Merge changes. Depending on the project setting, this may be [when the pipeline succeeds](merge_requests/merge_when_pipeline_succeeds.md), adding to a [Merge Train](../../ci/merge_request_pipelines/pipelines_for_merged_results/merge_trains/index.md), etc. |
| `/move <path/to/project>` | ✓ | | | Move this issue to another project. |
| `/parent_epic <epic>` | | | ✓ | Set parent epic to `<epic>`. The `<epic>` value should be in the format of `&epic`, `group&epic`, or a URL to an epic ([introduced in GitLab 12.1](https://gitlab.com/gitlab-org/gitlab/-/issues/10556)). **(ULTIMATE)** |
| `/rebase` | | ✓ | | Rebase source branch. This will schedule a background task that attempt to rebase the changes in the source branch on the latest commit of the target branch. If `/rebase` is used, `/merge` will be ignored to avoid a race condition where the source branch is merged or deleted before it is rebased. If there are merge conflicts, GitLab will display a message that a rebase cannot be scheduled. Rebase failures will be displayed with the merge request status. |
| `/reassign_reviewer @user1 @user2` | | ✓ | | Replace current reviewers with those specified. **(STARTER)** |
| `/relate #issue1 #issue2` | ✓ | | | Mark issues as related. **(STARTER)** |
| `/remove_child_epic <epic>` | | | ✓ | Remove child epic from `<epic>`. The `<epic>` value should be in the format of `&epic`, `group&epic`, or a URL to an epic ([introduced in GitLab 12.0](https://gitlab.com/gitlab-org/gitlab/-/issues/7330)). **(ULTIMATE)** |
| `/remove_zoom` | ✓ | | | Remove Zoom meeting from this issue ([introduced in GitLab 12.4](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/16609)). |

| `/shrug <comment>` | ✓ | ✓ | ✓ | Append the comment with `¯\_(ツ)_/¯`. |
| `/spend <time(-<h>h <mm>m)> <date(<YYYY-MM-DD>)>` | ✓ | ✓ | | Subtract spent time. Optionally, specify the date that time was spent on. For example, `/spend time(-1h 30m)` or `/spend time(-1h 30m) date(2018-08-26)`. |
| `/spend <time(<h>h <mm>m)> <date(<YYYY-MM-DD>)>` | ✓ | ✓ | | Add spent time. Optionally, specify the date that time was spent on. For example, `/spend time(1h 30m)` or `/spend time(1h 30m) date(2018-08-26)`. |
| `/submit_review` | | ✓ | | Submit a pending review ([introduced in GitLab 12.7](https://gitlab.com/gitlab-org/gitlab/-/issues/8041)). **(PREMIUM)** |
