calibre-ebooks@1.0.12

CAUTION· static only

Publisher claims: "calibre-ebooks is an OpenClaw skill for querying and operating a local Calibre library through a local Books API and helper scripts. It works only with books already available in the configured Calibre library and does not download, search, or add books from external sources. The project includes agent workflow guidance, a Python API client, a FastAPI server, semantic RAG support, systemd services, and local environment-based configuration."
