What problem does it solve? Working with Feishu (Lark) cloud documents programmatically requires handling multiple API endpoints for reading, writing, and block-level editing. This Skill consolidates all document operations into one tool with an action parameter, so you can manage Feishu docs directly from conversation. ## Core Features & Use Cases - Full Document Operations: Read, create, overwrite, and append markdown content to Feishu documents using a doc_token extracted from the document URL. - Block-Level Editing: List all blocks, inspect individual blocks, update text content, or delete specific blocks for fine-grained document manipulation. - Structured Content Handling: Detect tables, images, and code blocks via block statistics, then retrieve full structured data with the list_blocks action. - Use Case: Paste a Feishu docx link and ask the assistant to summarize its content, append a meeting-notes section, or update a specific paragraph without leaving the chat. ## Quick Start Read the Feishu document at https://xxx.feishu.cn/docx/ABC123def and summarize its content for me.
