DeepSeek Harness Feishu Plugin (dsh-plugin-feishu)

`dsh-plugin-feishu` is a Node.js plugin purpose-built for DeepSeek Harness, enabling direct interaction between agents and the Feishu ecosystem. It has no external dependencies and provides 25 tools covering chat messages, cloud documents (including charts and tables), multi-dimensional tables, spreadsheets, and permission management. Developers must configure it using credentials from a self-built enterprise Feishu app, with support for environment variable injection. The plugin supports local rendering of documents and charts, but be mindful of ASCII character limitations. All credentials are handled locally only, making it suitable for developers who need to operate the Feishu ecosystem directly within DeepSeek Harness.
