About the project

Pinvou/pinvou-agent is an open-source desktop workspace where an AI agent helps with work, visual design, and software development. People use it to work with files and knowledge, create editable visual artifacts, connect coding agents to projects, and extend the workspace with tools, MCP servers, skills, and workflows; the catalogue skills add capabilities to that environment.

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

wecomcli-message scanned grade A with 1 finding 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.

企业微信发送消息

执行任何 wecom-cli 命令前,必须先读取并完成 wecomcli-shared 技能的公共前置检查。

  1. 可以向授权人发送消息。
  2. 可以向授权人以外的、机器人最近有消息往来的聊天会话(单聊和群聊)发送消息。

适用范围

适用

  • 适用于给授权人发消息,使用 wecom-cli identity whoami 获取授权人ID,可作为 chat_id 使用,无需调用 sessions list
  • 适用于查询当前有权限发送消息的聊天会话范围并给这些范围中的成员或群聊发送 Markdown 消息、图片、文件、AMR 语音或视频

不适用

  • 发送对象不是授权人且不在本次 sessions list 返回结果中 → 告知用户当前只能向最近活跃的会话或授权人发送

技能依赖

调用依赖技能前,必须先完整读取对应 SKILL.md

依赖技能 触发场景 数据流向
wecomcli-media 发送图片、文件、语音或视频时只有本地文件路径,没有可直接复用的 media_id 包含媒体上传接口,如没有已有的 media_id,必须先阅读该技能获取 media_idmedia upload 以本地 file_path 上传,type 为可选入参(image/voice/video/file);发送时以上传响应返回的 type 对齐 msg_type

获取能发送消息的会话列表

命令

wecom-cli message aibot sessions list

返回

字段 类型 说明
sessions array 会话列表,按最后一条消息时间从新到旧排序,具体数量以实际回包为准
sessions[].chat_id string 会话 ID
sessions[].chat_name string 群名称或单聊名称
sessions[].chat_type string single 单聊或 group 群聊
sessions[].last_msg_time string 最后一条消息时间,格式 YYYY-MM-DD HH:MM:SS
sessions_count integer sessions 数组元素数量

chat_id 来源

向授权人以外的用户发送消息,调用 wecom-cli message aibot send 前,需要先调用一次 sessions list,然后从本次返回的 sessions[] 中选定目标项,把该项的 chat_id 原样复制到 send.chat_id

以下值都不能直接作为 send.chat_id

  • 用户输入的 ID
  • 之前轮次或历史上下文保存的 chat_id
  • wecomcli-contact 返回的 userid
  • 根据姓名、群名或其他字段自行构造的值

这些值最多只能作为匹配线索;最终发送参数必须重新取自本次 sessions list 的匹配项。

目标会话匹配

  • 聊天名称:在本次 sessions[] 中按非空 chat_name 精确匹配;不能精确匹配需要向用户反问确认发送目标,唯一命中时从匹配项复制 chat_id
  • 最近第一个/最近某个会话:按 sessions[] 原始顺序选择用户明确指定的项。
  • 用户提供 ID:只能与本次 sessions[].chat_id 做完全相等校验;命中后仍从匹配项复制 chat_id,不能直接复用用户输入值。

匹配结果处理:

  • 唯一匹配时继续发送。
  • 多个聊天会话候选时,按返回顺序展示聊天名和最后消息时间,让用户选择。
  • 用户完成选择后,必须重新调用 sessions list,再用选定对象匹配当次返回值。
  • 无匹配时停止发送,如实告知目标不在本次返回的最近会话中;不要接受外部 chat_id 绕过限制。
  • sessions_count=0 时停止发送,告知当前没有可发送的最近会话。
  • 展示会话列表时保持接口原始顺序;展示名称和时间,不展示内部 chat_id

发送消息

前置条件

调用本接口前必须完成以下步骤:

  1. 根据发送对象选择调用 wecom-cli message aibot sessions list获取 chat_idwecom-cli identity whoami 获取授权人ID。
  2. 在本次列表中唯一匹配目标。
  3. 如果发送授权人以外的对象,从列表中匹配项原样复制 sessions[].chat_id
  4. 目标是媒体消息时,再准备对应的 media_id

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.
