This gives Claude direct access to AWS S3 through the Membrane CLI, handling all the auth headaches so you can skip straight to managing buckets and objects. You authenticate once with `membrane login`, connect to AWS through their OAuth flow, then search for actions with natural language queries or proxy requests directly to the S3 API. Membrane keeps credentials fresh automatically. The skill shines when you need to script S3 operations without wrestling with AWS SDK configuration or storing keys locally. Free tier supported, MIT licensed, and the action discovery approach means you're not guessing at API endpoints.
