Create, read, edit, and manage Lark documents with content extraction, summarization, and formatting support. Supports three document types: Docx, Wiki, and Cloud Documents; handles embedded spreadsheets, multidimensional tables, and whiteboards by extracting tokens for downstream skill routing Core operations include fetch (with scoping and detail levels), create (XML or Markdown), update (str_replace, block operations, append, overwrite), and media management (insert, download, preview) All docs +create , docs +fetch , and docs +update commands require --api-version v2 flag; defaults to DocxXML format unless Markdown is explicitly requested Recognizes Feishu document URLs and tokens from both feishu.cn and doubao.com domains; routes based on URL path patterns and token type, not domain alone

Manage files, folders, and documents in Lark Drive with upload, download, import, comments, and permissions. Upload and download files; create folders; copy, move, and delete files; import local Word/Markdown/Excel/CSV/PPTX and Base snapshots as cloud documents Add full-text or block-level comments to docs, sheets, slides, and files; manage comment replies and reactions; subscribe to comment change events Manage document permissions, transfer ownership, and apply for access; update file titles across docx, sheet, bitable, file, folder, and wiki types Auto-unwrap wiki URLs to underlying document types (docx, sheet, bitable, slides, file); inspect document metadata and view access records Sync local directories with Drive folders using hash-based or timestamp-based diffing; version history, export, and secure label management

Manage Lark Wiki spaces, members, nodes, and document organization hierarchies. Create, list, and delete knowledge spaces; retrieve space and node information via token or URL Add, remove, and list space members with support for users, groups, and departments; enforces identity constraints (bot identity cannot manage department members) Create, move, copy, and delete wiki nodes; organize documents and shortcuts within space hierarchies Prioritizes user identity over bot identity for personal knowledge resources; includes safety checks for destructive operations like space deletion requiring explicit user confirmation

Create and edit Lark Office slides with XML protocol, supporting presentation creation, page management, and content modification. Supports three creation workflows: one-step creation for simple slides, two-step creation (empty presentation + page-by-page addition) for complex content, and block-level editing of existing pages without reordering Handles slide operations including create, read, delete, and replace at both presentation and individual page levels; automatically parses /slides/ and /wiki/ URLs to extract presentation tokens Requires planning layer (slide_plan.json) before XML generation for new presentations or major rewrites; includes visual planning (layout_type, visual_focus, text_density) and asset planning with fallback strategies Enforces strict XML validation: text must use <content><p>...</p></content> , images require uploaded file_tokens (no external URLs), and all complex content undergoes post-creation verification against validation checklist Provides template search, summarization, and extraction via template_tool.py to avoid boilerplate; prioritizes user identity ( --as user ) for personal content operations
