lark-openapi-explorer

A skill for finding and calling Lark APIs that are not already available through existing commands. An API is a defined way for software to request work from another service.

In plain words
What is it for?
It can search Lark’s official documentation for an endpoint and call that endpoint through the Lark command-line tool.
Why use it?
It helps when an existing Lark skill or command cannot perform the needed operation, while requiring the API to be located in official documentation first.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-openapi-explorer 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.

⚙️ Cowork / Claude Desktop 执行环境说明(自动注入)

本技能依赖本地 lark-cli@larksuite/cli,可用 command -v lark-cli 定位)及其 ~/.lark-cli 登录态(应用密钥存于 macOS keychain)。

在 Cowork 中运行任何 lark-cli 命令时,必须在本地 macOS 上执行(使用 Desktop Commander 的 start_process / interact_with_process,或其它本地 shell 工具),不要用隔离的 Linux 沙箱 mcp__workspace__bash——沙箱里没有 lark-cli、也读不到 keychain。 执行前确保 npm 全局 bin 目录(npm prefix -g 输出目录下的 bin)在 PATH 中。

(在 Claude Code 中可忽略本说明,lark-cli 在本机 shell 直接可用。)

OpenAPI Explorer

前置条件: 先阅读 ../lark-shared/SKILL.md 了解认证、身份切换和安全规则。

当用户的需求无法被现有 skill 或 CLI 已注册 API 覆盖时,使用本技能从飞书官方 markdown 文档库中逐层挖掘原生 OpenAPI 接口,然后通过 lark-cli api 裸调完成任务。

文档库结构

飞书 OpenAPI 文档以 markdown 层级组织:

llms.txt                          ← 顶层索引,列出所有模块文档链接
  └─ llms-<module>.txt            ← 模块文档,包含功能概述 + 底层 API 文档链接
       └─ <api-doc>.md            ← 单个 API 的完整说明(方法/路径/参数/响应/错误码)

文档入口:

品牌 入口 URL
飞书 (Feishu) https://open.feishu.cn/llms.txt
Lark https://open.larksuite.com/llms.txt

所有文档以中文编写。如果用户使用英文交流,需将文档内容翻译为英文后输出。

挖掘流程

严格按以下步骤逐层检索,不要跳步或猜测 API

Step 1:确认现有能力不足

# 先检查是否已有对应的 skill 或已注册 API
lark-cli <可能的service> --help

如果已有对应命令或 shortcut,直接使用,不需要继续挖掘

Step 2:从顶层索引定位模块

用 WebFetch 获取顶层索引,找到与需求相关的模块文档链接:

WebFetch https://open.feishu.cn/llms.txt
  → 提取问题:"列出所有模块文档链接,找出与 <用户需求关键词> 相关的链接"
  • 飞书品牌使用 open.feishu.cn
  • Lark 品牌使用 open.larksuite.com
  • 如不确定用户品牌,默认使用飞书

Step 3:从模块文档定位具体 API

用 WebFetch 获取模块文档,找到具体 API 的文档链接:

WebFetch https://open.feishu.cn/llms-docs/zh-CN/llms-<module>.txt
  → 提取问题:"找出与 <用户需求> 相关的 API 说明和文档链接"

Step 4:获取 API 完整规范

用 WebFetch 获取具体 API 文档,提取完整的调用规范:

WebFetch https://open.feishu.cn/document/server-docs/.../<api>.md
  → 提取问题:"返回完整 API 规范:HTTP 方法、URL 路径、路径参数、查询参数、请求体字段(名称/类型/必填/说明)、响应字段、所需权限、错误码"

Step 5:通过 CLI 调用 API

使用 lark-cli api 裸调:

# GET 请求
lark-cli api GET /open-apis/<path> --params '{"key":"value"}'

# POST 请求
lark-cli api POST /open-apis/<path> --data '{"key":"value"}'

# PUT 请求
lark-cli api PUT /open-apis/<path> --data '{"key":"value"}'

# DELETE 请求
lark-cli api DELETE /open-apis/<path>

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.

lark-openapi-explorer is a skill published in the GitHub repository DropFan/claude-code-plugins (7 stars, last pushed 27d ago), licensed MIT. It adds 76 tokens to every session and 1,712 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
