feishu-doc

A tool for reading, replacing, appending to, and creating Feishu documents, including documents shared through docx links. Feishu is a workplace collaboration service with online documents.

In plain words
What is it for?
Reading document text, creating documents, replacing or appending Markdown content, and inspecting structured content such as tables and images.
Why use it?
It removes the need to open Feishu and edit documents manually when an agent needs to work with their contents. It can also expose document blocks when plain text is not enough.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

feishu-doc scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to feishu-doc — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Feishu Document Tool

Single tool feishu_doc with action parameter for all document operations.

Token Extraction

From URL https://xxx.feishu.cn/docx/ABC123defdoc_token = ABC123def

Actions

Read Document

{ "action": "read", "doc_token": "ABC123def" }

Returns: title, plain text content, block statistics. Check hint field - if present, structured content (tables, images) exists that requires list_blocks.

Write Document (Replace All)

{ "action": "write", "doc_token": "ABC123def", "content": "# Title\n\nMarkdown content..." }

Replaces entire document with markdown content. Supports: headings, lists, code blocks, quotes, links, images (![](url) auto-uploaded), bold/italic/strikethrough.

Limitation: Markdown tables are NOT supported.

Append Content

{ "action": "append", "doc_token": "ABC123def", "content": "Additional content" }

{ "action": "create", "title": "New Document", "folder_token": "fldcnXXX" }

List Blocks

{ "action": "list_blocks", "doc_token": "ABC123def" }

Returns full block data including tables, images. Use this to read structured content.

Get Single Block

{ "action": "get_block", "doc_token": "ABC123def", "block_id": "doxcnXXX" }

Update Block Text

{
  "action": "update_block",
  "doc_token": "ABC123def",
  "block_id": "doxcnXXX",
  "content": "New text"
}

Delete Block

{ "action": "delete_block", "doc_token": "ABC123def", "block_id": "doxcnXXX" }

Reading Workflow

  1. Start with action: "read" - get plain text + statistics
  2. Check block_types in response for Table, Image, Code, etc.
  3. If structured content exists, use action: "list_blocks" for full data

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
