What problem does it solve? It lets an AI agent operate Feishu (Lark) instant messaging on your behalf: sending and replying to messages, searching chat history, managing group members, downloading message attachments, and handling interactive card callbacks without manually calling the OpenAPI. ## Core Features & Use Cases - Messaging & Search: Send text, markdown, post, media, and interactive card messages; reply in threads; search messages and chats with keyword, sender, and time filters. - Chat & Member Management: Create group or topic chats, list members, update names and descriptions, manage pins, reactions, bookmarks, feed shortcuts, and feed groups. - Resources & Cards: Upload images, download message files with automatic chunked download for large files, and listen for card.action.trigger callbacks to update interactive cards. - Use Case: Ask the agent to find the 'daily report' group, read today's messages, download the attached spreadsheet, and reply with a summary card whose buttons trigger follow-up actions. ## Quick Start Use the lark-im skill to send a markdown message saying 'Meeting moved to 3pm' to the group chat named 'Project Discussion'.
