Chat with DeepSeek Harness Agent in Feishu via dsh-lark

`dsh-lark` is a Feishu/Lark channel plugin for DeepSeek Harness maintained by omdsh-dev (npm package name: `dsh-lark-channel`, licensed under BSD-3-Clause). After scanning the code to create an application, users can assign tasks and view execution progress in private chats or groups, and use cards to handle inquiries, plan confirmations and tool approvals without requiring public network callbacks. This article checks the installation commands, slash commands, multi-agent collaboration and environment requirements against the directory page and GitHub repository.
