# Rerun Arnica Status Check

Post \[a] rerun on a pull request to trigger a fresh Arnica status check without retriggering other CI pipelines.

## Summary

To rescan a pull request with Arnica, post `[a] rerun` as a standalone comment on the pull request. Arnica starts a fresh status check run for that pull request.

This works across all supported source control platforms:

* GitHub
* GitLab
* Bitbucket
* Azure DevOps

## Why use `[a] rerun`

Pushing an empty commit also resynchronizes the pull request and retriggers other CI pipelines and workflows, which wastes time and compute.

`[a] rerun` refreshes only the Arnica status check. Other checks and pipelines are not restarted by this comment.

## How to rerun the status check

1. Open the pull request in your source control platform.
2. Add a new comment that contains only:

```
[a] rerun
```

3. Submit the comment.
4. Wait for Arnica to queue and complete a new status check run on the pull request.

{% hint style="info" %}
The comment must be a standalone pull request comment with the exact text `[a] rerun`. Do not embed the command in a longer comment or reply thread.
{% endhint %}

## When to use it

Use `[a] rerun` when:

* The Arnica status check failed and you want Arnica to scan the pull request again.
* Policy, configuration, or finding changes should be reflected on the pull request without pushing new commits.
* You need a fresh Arnica run for any other reason.

{% hint style="warning" %}
`[a] rerun` does not change findings or policies on its own. It re-executes the Arnica status check for the current pull request state. If findings still match a failing policy rule, the status check can fail again after the rerun.
{% endhint %}
