Feishu Doc Skill

Fetch content from Feishu (Lark) Wiki, Docs, Sheets, and Bitable. Write and update documents.

Prerequisites

• Install feishu-common first.
• This skill depends on ../feishu-common/index.js for token and API auth.

Capabilities

• Read: Fetch content from Docs, Sheets, Bitable, and Wiki.
• Create: Create new blank documents.
• Write: Overwrite document content with Markdown.
• Append: Append Markdown content to the end of a document.
• Blocks: List, get, update, and delete specific blocks.

Long Document Handling (Unlimited Length)

To generate long documents (exceeding LLM output limits of ~2000-4000 tokens):

1. Create the document first to get a doc_token.
2. Chunk the content into logical sections (e.g., Introduction, Chapter 1, Chapter 2).
3. Append each chunk sequentially using feishu_doc_append.
4. Do NOT try to write the entire document in one feishu_doc_write call if it is very long; use the append loop pattern.

Usage

# Read
node index.js --action read --token <doc_token>

# Create
node index.js --action create --title "My Doc"

# Write (Overwrite)
node index.js --action write --token <doc_token> --content "# Title\nHello world"

# Append
node index.js --action append --token <doc_token> --content "## Section 2\nMore text"
