 ### Required Permissions
 
-This action requires the `pull-request: write` permission to add a comment to your pull request. If you're using the default `GITHUB_TOKEN`, ensure that you include both `pull-request: write` and `contents: read` permissions in the job. The `contents: read` permission is necessary for the `actions/checkout` action to checkout the repository. This is particularly important for new repositories created after GitHub's [announcement](https://github.blog/changelog/2023-02-02-github-actions-updating-the-default-github_token-permissions-to-read-only/) to change the default permissions to `read-only` for all new `GITHUB_TOKEN`s.
