OpenBook RSS Reader: A Local-First RSS Reading and Knowledge Collection Plugin

OpenBook, a DeepSeek Harness plugin, is a local-first RSS reader refactored as a DSH plugin, offering a three-pane reading interface, note management, and full-text reading capabilities. It runs using native Cordis services, supports environment awareness, can inject article content into the Agent context, and enables discussion, summarization, and note organization for articles via commands and tools. Data is stored in SQLite, and SSRF protection is enabled by default. Once installed via the CLI, it integrates seamlessly into the Web UI, deeply combining knowledge collection with agent workflows.
