Slop Detection

Automatically detect low-quality, AI-generated pull requests on public GitHub repositories.

|

When a pull request is opened on a public GitHub repository, CodeRabbit analyzes the changes for signals of low-quality, AI-generated content. If the PR is classified as slop, CodeRabbit notes this in the PR Walkthrough comment. Additionally, you can configure a label in your settings to get the suspicious PRs labeled automatically.

The detection runs as part of CodeRabbit’s standard review pipeline, no additional setup is required.

Configuration

Configuration file

Configure the slop_detection section in your .coderabbit.yaml file:

.coderabbit.yaml

reviews:
  slop_detection:
    enabled: true   # Runs automatically on public repos unless disabled
    label: "slop"   # Add a label to apply when slop is detected (no label applied by default)

Web UI

1. Go to CodeRabbit settings for your repository or organization.
2. Switch the mode (bottom-left) to All Settings.
3. Navigate to Reviews → General.
4. Scroll down to the Anti-Slop section to toggle Enabled on or off, and optionally set a custom Label.

Disabling Slop Detection

To disable Slop Detection on a repository, set enabled to false or disable it in the web UI:

.coderabbit.yaml

reviews:
  slop_detection:
    enabled: false

Label flagged PRs

By default, Slop Detection does not apply any label, it only adds a note to the PR Walkthrough comment. To also apply a label to flagged PRs, set the label field:

.coderabbit.yaml

reviews:
  slop_detection:
    label: "slop"   # Or any label name you prefer, e.g. "ai-spam"

Frequently asked questions

Does Slop Detection work on private repositories?

No. Slop Detection only runs on public GitHub repositories.

Will Slop Detection block a PR from being merged?

No. Slop Detection does not block merges. When a PR is classified as slop, a note is added to the PR Walkthrough comment. If a label is configured, it is also applied so maintainers can filter and triage PRs at their discretion.

Can I automatically close slop PRs?

Not at the moment. CodeRabbit is currently gathering data and tuning the detection mechanism to ensure accuracy.
