Works in 4 steps: 克制 @：默认不主动 @ 其他机器人，除非用户明确要求或触发协作关键字 → 每次最多 @ 1 个：一条回复中最多 @ 1 个机器人 → 区分"提到"和"请求"：提到用名字，请求才用标签 → …
SKILL.md covers 核心原则, 什么时候该 @, 任务协作闭环（最重要的规则） and 标签格式, plus 4 more sections
Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

A2a Collaboration Guide is an agent skill from Leochens/feishu-bot-chat-plugin. A2A 群内协作规则速查手册。仅在飞书群聊中使用，私聊时不适用。当以下情况时使用此 Skill： (1) 不确定是否应该 @ 其他机器人 (2) 不确定如何正确使用 🔕仅通知标记 (3) 收到其他机器人 @ 你的消息后不确定如何回应 (4) 用户询问"你们怎么协作的？" (5) 遇到协作边界情况需要参考

Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: OpenClaw plugin for bot-to-bot @ communication in Feishu group chats. The licence is MIT.

Example prompts

“你们怎么协作的？”
“/a2a-collaboration-guide”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

克制 @：默认不主动 @ 其他机器人，除非用户明确要求或触发协作关键字
每次最多 @ 1 个：一条回复中最多 @ 1 个机器人
区分"提到"和"请求"：提到用名字，请求才用标签
任务必须闭环：收到任务型 @ 后，完成任务必须 @ 回发起者汇报结果

What it can do on your machine

Read from SKILL.md and the folder at commit 69b0fdc. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

A2a Collaboration Guide loads about 522 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 161 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~47
When it runs · the whole SKILL.md, loaded when a task matches: ~522

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

A2A 群内协作规则速查

核心原则

克制 @：默认不主动 @ 其他机器人，除非用户明确要求或触发协作关键字
每次最多 @ 1 个：一条回复中最多 @ 1 个机器人
区分"提到"和"请求"：提到用名字，请求才用 <at> 标签
任务必须闭环：收到任务型 @ 后，完成任务必须 @ 回发起者汇报结果

什么时候该 @

场景	是否 @	说明
用户说"让后端看看"	✅ @	用户明确要求
用户说"群内协作完成这个需求"	✅ @	触发协作关键字
收到任务请求，完成后需要汇报	✅ @ 回发起者	必须 @ 回，让发起者获得上下文
回复中顺便提到某个 bot 的能力	❌ 不 @	只是提到，用名字即可
只是通知对方一个信息	用 🔕仅通知	加标记避免回传

任务协作闭环（最重要的规则）

当用户 @ 你并要求你完成一个需求时，完整的协作链路是：

用户 @ 主Agent → 主Agent 拆任务 @ 子Agent → 子Agent 完成后 @ 回主Agent → 主Agent 汇总回复用户

关键规则：

你作为子 Agent 被 @ 分配了任务 → 完成后必须 @ 回发起者，汇报结果
你作为主 Agent 收到子 Agent 的结果回传 → 不要再 @ 回子 Agent，整理结果回复用户
每一步的 @ 回传都是必须的，否则主 Agent 会丢失上下文，不知道任务进展

判断是否需要 @ 回：

对方给你分配了任务、请你执行操作、请你回答问题 → ✅ 必须 @ 回
对方只是通知你信息（带 🔕仅通知）→ ❌ 不需要 @ 回
对方是在回传结果给你 → ❌ 不需要 @ 回（你是主 Agent，汇总即可）

`<at>` 标签格式

<at user_id="ou_xxxx">bot名字</at>

直接写在回复正文中即可，飞书会原生投递给目标机器人。

🔕仅通知标记

当你 @ 其他机器人只是单向通知、共享结果，不需要对方回复或 @ 你时：

🔕仅通知 <at user_id="ou_xxxx">bot名字</at> 排期已确认，按原计划推进即可

对方收到后不需要 @ 回你。

收到 @ 消息后的行为

当其他机器人 @ 你时，消息开头会自动注入发送者信息：

[来自机器人「mac-后端」— 如需 @ 回对方请使用：<at user_id="ou_xxxx">mac-后端</at>]

直接复制其中的 <at> 标签即可 @ 回对方，不需要自己查找 ID。

收到「任务请求」

处理任务
完成后必须 @ 回发起者（使用消息开头提供的 <at> 标签），汇报结果

收到「结果回传」（你是主 Agent）

不要 @ 回对方
整理结果，直接回复用户
如果还有其他子任务待分配，继续 @ 下一个 Agent

收到「仅通知」

不要 @ 回对方
阅读信息，自行处理即可

常见错误

错误	正确做法
收到任务后完成了但没 @ 回发起者	必须 @ 回，否则发起者不知道你完成了
收到结果回传后又 @ 回对方	直接整理结果回复用户，不要 @
在回复中用 `<at>` 标签提到 bot 但不需要它做事	用文字名字提到即可，不用标签
一条消息 @ 了多个 bot	每次最多 @ 1 个，需要多个就分多轮
通知类消息没加 🔕仅通知	不需要回复的 @ 一定要加标记
启动了服务但没有持久化，回复后服务就停了	用 `pm2` 或 `nohup` 启动，确保服务持续运行

协作关键字

以下关键字出现时，可以主动发起协作：

"群内协作"、"分配任务"、"协作完成"
"让 xxx 看看"、"问问 xxx"
"大家一起"、"各自负责"
