What problem does it solve? Reading Feishu (Lark) documents programmatically requires handling authentication tokens, document types, and complex block structures. This Skill wraps the official Feishu Open API so you can pull document content, metadata, and full block hierarchies with simple commands instead of writing API integration code yourself. ## Core Features & Use Cases - Document Content Extraction: Read Docx, legacy Doc, Sheet, and Slide documents using their document tokens, with structured JSON output. - Full Block Access: Retrieve complete block hierarchies including text, headings, tables, images, code blocks, and lists with parent-child relationships. - Robust Error Handling: Built-in token validation, permission checks, retry logic, and clear diagnostics for common Feishu API error codes. - Use Case: You need to migrate a knowledge base of Feishu docs into another system. Run the blocks script against each document token to export the full structured content as JSON for downstream transformation. ## Quick Start Set up your Feishu app credentials in the config file, then ask the assistant to read a Feishu document by providing its document token from the URL.
