Minio

This gives Claude the ability to interact with MinIO's S3-compatible object storage through the mc command line client. You get standard bucket operations like upload, download, and listing, plus some genuinely useful stuff like pre-signed URL generation for temporary file sharing and mirror commands for continuous directory syncing. The skill covers the mc tool primarily but also shows fallback methods using curl with AWS signature authentication and the AWS CLI, which is smart since MinIO is fully S3-compatible. Most helpful for self-hosted storage scenarios where you need Claude to manage files without exposing credentials directly, especially the pre-signed URL workflow.
