 ### Step 2.3. Running RuboCop

Now you'll get into the nitty gritty details of the [RuboCop linter](https://rubocop.readthedocs.io/en/latest/basic_usage/#rubocop-as-a-code-style-checker) and [Checks API annotations](/rest/reference/checks#create-a-check-run).

 The following code runs RuboCop and saves the style code errors in JSON format. Add this code below the call to `clone_repository` you added in the [previous step](#step-22-cloning-the-repository) and above the code that updates the check run to complete.

 Because this code stores the RuboCop results in a `@report` variable, it can safely remove the checkout of the repository. This code also parses the JSON so you can easily access the keys and values in your GitHub App using the `@output` variable.

 When the `offense_count` is zero, the CI test is a `success`. If there are errors, this code sets the conclusion to `neutral` in order to prevent strictly enforcing errors from code linters. But you can change the conclusion to `failure` if you would like to ensure that the check suite fails when there are linting errors.
 
-When errors are reported, the code above iterates through the `files` array in the RuboCop report. For each file, it extracts the file path and sets the annotation level to `notice`. You could go even further and set specific warning levels for each type of [RuboCop Cop](https://rubocop.readthedocs.io/en/latest/cops/), but to keep things simpler in this quickstart, all errors are set to a level of `notice`.

 This code also iterates through each error in the `offenses` array and collects the location of the offense and error message. After extracting the information needed, the code creates an annotation for each error and stores it in the `annotations` array. Because annotations only support start and end columns on the same line, `start_column` and `end_column` are only added to the `annotation` object if the start and end line values are the same.

 If you've made it this far, kudos! 👏 You've already created a CI test. In this section, you'll add one more feature that uses RuboCop to automatically fix the errors it finds. You already added the "Fix this" button in the [previous section](#step-25-updating-the-check-run-with-ci-test-results). Now you'll add the code to handle the `requested_action` check run event triggered when someone clicks the "Fix this" button.
 
-The RuboCop tool [offers](https://rubocop.readthedocs.io/en/latest/basic_usage/#auto-correcting-offenses) the `--auto-correct` command-line option to automatically fix errors it finds. When you use the `--auto-correct` feature, the updates are applied to the local files on the server. You'll need to push the changes to GitHub after RuboCop does its magic.

 To push to a repository, your app must have write permissions for "Repository contents." You set that permission back in [Step 2.2. Cloning the repository](#step-22-cloning-the-repository) to **Read & write**, so you're all set.
