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 without learning the underlying API surface. ## 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, inspect, update, and delete individual blocks (headings, paragraphs, code, todos) for fine-grained document manipulation. - Structured Content Handling: Detect tables, images, and other structured blocks via read statistics, then retrieve full block data with list_blocks. - Use Case: A user pastes a Feishu doc link and asks to summarize it, then append meeting notes. The Skill extracts the doc_token, reads the content, and appends the new markdown section. ## Quick Start Read the Feishu document at https://xxx.feishu.cn/docx/ABC123def and summarize its content for me.
