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

wecom 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 26d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (tools/get_dept_users/index.ts, tools/get_user/index.ts, tools/list_departments/index.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

企业微信技能

企业微信(WeCom)是腾讯面向企业的 IM 平台,具备组织架构(部门树)、应用消息推送等能力。

核心原则

组织架构是核心

企业微信的用户隶属于部门树,查询操作需要从组织架构出发:

wecom_list_departments → 获取部门列表(默认从根部门 ID=1 开始)
wecom_get_dept_users(dept_id) → 获取部门下的用户列表
wecom_get_user(user_id) → 获取用户详情

消息发送

wecom_send_text 通过应用消息接口发送文本消息,需要知道接收者的 userid。 群消息通过 webhook 回调自动处理,不需要主动调用发送工具。

工具分类

组织架构

工具 用途 说明
wecom_list_departments 部门列表 默认从根部门 ID=1 开始
wecom_get_dept_users 部门用户列表 返回简单用户信息
wecom_get_user 用户详情 需要通讯录权限

消息

工具 用途 说明
wecom_send_text 发送文本消息 发给指定用户,通过应用消息接口

易错点

  1. 部门查询从根部门 ID=1 开始。不知道部门 ID 时先 list_departments 获取整棵部门树。
  2. 消息发送需要 userid,不是用户名或昵称。仅有昵称时先通过 get_dept_users 查找。
  3. 企业微信不支持机器人撤回消息,一旦发出无法撤回。
  4. Access Token 有效期 7200 秒,适配器会自动刷新。
Files

What ships with it

4 files 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.
