Grimmory Self Hosted Library

If you're running a personal book server, this gives Claude the context to help you deploy and configure Grimmory, a self-hosted library manager that handles EPUBs, PDFs, comics, and syncs with Kobo devices. The skill covers the full Docker Compose setup with MariaDB, the bookdrop auto-import folder that watches for new files and fetches metadata from Google Books, and the network storage mode for NFS or SMB mounts. It also includes Java controller patterns and API routes if you're extending the backend. Useful when you want Claude to troubleshoot your docker-compose.yml, explain OPDS catalog endpoints, or help you write a custom import script that talks to the REST API.
