What it does
A2a Mode Switch is an agent skill from Leochens/feishu-bot-chat-plugin. A2A 协作模式切换指南。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) 用户想临时禁用协作（"只跟你聊"、"不要叫其他 bot"） (2) 用户想切换协作策略（优先速度 vs 优先质量） (3) 用户想恢复协作模式 (4) 用户想指定只与某些 bot 协作
Its SKILL.md is about 290 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
- “不要叫其他 bot”
- “/a2a-mode-switch”
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 Mode Switch loads about 293 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 69 words of instructions outside code blocks.
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 协作模式切换
模式定义
| 模式 | 触发词 | 行为 |
|---|---|---|
| 🟢 正常模式 | 默认 | 按协作规则，用户要求或关键字触发时 @ 其他 bot |
| 🔴 独立模式 | "只跟你聊"、"不要叫别人"、"单独对话" | 不 @ 任何其他 bot，所有问题自己处理 |
| 🟡 指定模式 | "只找后端和前端"、"这次只需要 xxx" | 只 @ 用户指定的 bot |
| 🔵 全力模式 | "全员协作"、"大家一起上" | 主动拆解任务分配给所有相关 bot |
模式识别
进入独立模式
用户：接下来只跟你聊，不要叫其他机器人
你：好的，切换到独立模式，后续我自己处理所有问题。需要恢复协作时告诉我。进入指定模式
用户：这个任务只需要后端和测试参与
你：收到，这次只协调后端和测试。其他 bot 不会参与。进入全力模式
用户：这个需求比较大，大家一起协作完成
你：好的，我来拆解任务分配给各个 bot。恢复正常模式
用户：好了，恢复正常
你：已恢复正常协作模式。模式下的行为差异
独立模式
- 不 @ 任何 bot，即使任务超出自己能力范围
- 如果遇到确实需要其他 bot 的情况，提示用户："这个任务可能需要后端协助，要切回协作模式吗？"
- 收到其他 bot 的 @ 仍正常响应（不影响被动协作）
指定模式
- 只 @ 用户指定的 bot
- 其他 bot 即使更合适也不主动 @
- 如果指定的 bot 无法完成任务，告知用户并建议调整
全力模式
- 主动分析任务，拆解并分配给所有相关 bot
- 不需要等用户逐个指定
- 使用 a2a-task-decompose skill 进行任务分解
注意事项
- 模式切换只影响当前对话上下文，不是永久设置
- 被动协作（收到其他 bot 的 @）不受模式限制，始终正常响应
- 如果用户没有明确切换模式，保持正常模式
- 模式切换时简短确认即可，不需要长篇解释
