lark-safe-write

lark-safe-write is a skill for Codex from tranfu-labs/tranfu-skills. It costs 78 tokens per session (2,847 once invoked), scanned A, original, MIT.

A safety procedure for creating or updating documents in Lark or Feishu, a workplace collaboration platform with shared wikis and documents. It requires checking access, making a backup, writing the content, and verifying the result.

In plain words
What is it for?
Use it when creating or replacing Lark wiki documents or DOCX files. It covers document types it supports and stops when extra permissions or manual checks are needed.
Why use it?
It reduces the risk of overwriting content, using the wrong document token, or assuming a write succeeded when indexing is still delayed.

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

lark-safe-write 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 11d 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.

Lark Safe Write

触发时机:任何需要向 Lark wiki 创建新文档节点、更新现有文档内容或覆盖文档的任务。 核心原则:先解析 token → 再备份 → 再写入 → 最后验证。凡覆盖必备份,写入必验证,验证失败禁止自动重试。

同类 Skill 对比

公司库内

暂无直接同类。公司库现有 lark-wiki(知识库查询)、lark-doc(云文档管理)等操作 skill,但无「写入安全」专项 skill。

外部世界

暂无(未找到公开可验证的 Lark/Feishu wiki 安全写入专项 skill)。

本 skill 独特价值

  • 唯一强制四步闭环:预检→备份→写入→验证,把覆盖风险消灭在发生前。
  • 精准解决 lark-cli 三大坑:wiki_token/obj_token 混淆、--markdown /path 路径当内容、异步索引导致验证失败。
  • 与现有 lark 生态互补:lark-wiki 查、lark-safe-write 写,形成完整读写链。

使用技巧

材料方案

  • 首次使用该 skill 前,确保 lark-cli 已配置 bot 身份(lark-cli auth test --as bot 通过)。
  • 写入内容包含链接时,禁用 <https://...> 自动链接语法,改用标准 [文本](https://...) 语法,避免飞书 docx 不兼容导致内容丢失。

推荐用法

  • 覆盖现有文档时,skill 会自动备份到 .backups/,操作完成后可手动检查备份文件确认无误。
  • 验证失败后禁止自动重试,需人工检查原因(常见:异步索引延迟不足、markdown 格式非法)。

已知限制

  • 仅支持 docx/doc 类型文档,sheet/bitable/slides 等类型会停止并建议转用对应 skill。
  • 无法处理需要复杂权限审批的 wiki 空间(如仅特定部门可见),需先在飞书控制台完成审批。

第一步:预检与 Token 解析(不可跳过)

1.1 身份与连通性

  • 所有命令必须携带 --bot 标志(或 --as bot
  • 执行 lark-cli auth test --as bot 确认 bot token 有效
  • 若失败:暂停执行,提示用户检查 LARK_APP_ID / LARK_APP_SECRET

1.2 解析目标 Token

用户输入可能是 wiki URL 或 wiki_token。

若用户给的是 wiki URL

https://xxx.larksuite.com/wiki/WIKITOKEN

提取 URL 中 /wiki/ 后的 token 作为 wiki_token

若用户直接给的是 token

  • wik 开头 → 这是 wiki_token,需要解析
  • dox / doc 开头 → 这是 obj_token(真实文档 token),可直接使用

1.3 wiki_token → obj_token 解析(关键!不可跳过)

wiki_token 不能直接用于文档读写。必须先用以下命令解析:

lark-cli wiki spaces get_node --params '{"token":"<wiki_token>"}' --as bot

从返回的 JSON 中提取:

  • node.obj_token → 这是真实的文档 token,后续所有读写操作都用它
  • node.obj_type → 文档类型(docx / doc / sheet / bitable / slides 等)
  • node.title → 文档当前标题

类型检查

  • obj_typedocxdoc:继续执行本文档流程
  • obj_typesheet / bitable / slides 等:停止执行,向用户说明本 skill 仅支持文档类型,建议转用对应的 skill(如 lark-sheets

1.4 权限确认

首次操作该 wiki 空间时,确认 bot 有 wiki:node:readwiki:node:createdrive:drive 权限。


第二步:备份(更新/覆盖场景必须执行)

仅当文档已存在(即用户提供了已有 wiki 的 URL/token)时执行。创建新文档可跳过。
