> ⚠️ Disclaimer: The configuration review tools provide read-only access to your arr settings. Any changes to your configuration must be made directly in the arr application interfaces. The AI's suggestions are recommendations only - always back up your configuration before making significant changes. The maintainers are not responsible for any configuration changes, data loss, or other issues that may arise from following AI-generated recommendations.
Access community-curated quality profiles, custom formats, and naming conventions from TRaSH Guides directly through Claude. These tools work without any *arr configuration - they fetch reference data from the TRaSH Guides GitHub repository.
