Lark Im

A comprehensive Lark (Feishu) instant messaging integration that handles the full spectrum of chat operations: sending messages, searching chat history, managing group members, and downloading files with automatic chunking for large attachments. The skill wraps Lark's IM APIs with smart shortcuts that handle identity switching between user and bot tokens, resolve P2P chat IDs automatically, and batch operations for efficiency. What makes this particularly solid is the upfront handling of Lark's complex permission model and the practical shortcuts for common workflows like threaded replies and message search across multiple chats.
