What problem does it solve? It lets you operate Feishu (Lark) instant messaging from the terminal without manually calling the Open Platform REST APIs, covering message sending, chat management, history search, and file downloads. ## Core Features & Use Cases - Message Operations: Send and reply to messages as text, Markdown, post, or media (image/file/video/audio), with thread replies and idempotency keys. - Chat Management: Create, search, update group chats, and manage members with correct user/bot identity selection. - Search & Retrieval: Search messages across chats with sender, time, and attachment filters, plus auto-pagination for work summaries; download message resources with automatic 8MB chunked downloads for large files. - Use Case: Ask the agent to find last week's discussion in a project group, then reply in-thread with a status update and attach a report file. ## Quick Start Ask the agent to send the message "Build passed" to the Feishu group named "project-release" using lark-im.
