What problem does it solve? It lets an AI agent operate Lark (Feishu) instant messaging end to end: sending and replying to messages, searching chat history, managing group members, downloading message attachments, and handling interactive card callbacks without manual console work. ## 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. - Group Administration: Create group or topic chats, list and search chats, manage members, managers, moderation, nicknames, pins, and per-user mute settings. - Resources & Cards: Upload images, download message files with automatic chunked download for large files, manage reactions, bookmarks, feed shortcuts and feed groups, and listen to card.action.trigger callbacks to update cards. - Use Case: Ask the agent to find the "release discussion" group, pull the last 50 messages with attachments downloaded, then post a summary card whose buttons trigger automated follow-up updates. ## Quick Start Ask the agent to send a message saying "Deployment finished" to the Lark group named "release-notices" using the lark-im skill.
