Subagent
Subagent 是 Qwen Code 中专用于处理特定类型任务的 AI 助手。你可以将专注性工作委托给配置了特定任务提示词、工具和行为的 AI 代理。
什么是 Subagent?
Subagent 是独立的 AI 助手,具备以下特性:
- 专注特定任务 - 每个 Subagent 都配置了针对特定工作类型的专用 system prompt
- 独立上下文 - 它们维护自己的对话历史,与主聊天窗口隔离
- 受控工具访问 - 你可以配置每个 Subagent 可使用的工具
- 自主运行 - 接收任务后,它们会独立工作直至完成或失败
- 提供详细反馈 - 你可以实时查看其进度、工具使用情况和执行统计信息
核心优势
- 任务专精:创建针对特定工作流(测试、文档、重构等)优化的代理
- 上下文隔离:将专项工作与主对话隔离开
- 可复用性:跨项目和会话保存并复用代理配置
- 访问控制:限制每个代理可用的工具,以提升安全性和专注度
- 进度可见:通过实时进度更新监控代理执行情况
Subagent 工作原理
- 配置:创建 Subagent 配置,定义其行为、工具和 system prompt
- 任务委派:主 AI 可自动将任务委派给合适的 Subagent
- 执行:Subagent 独立工作,使用配置的工具完成任务
- 结果返回:将结果和执行摘要返回给主对话
快速上手
快速开始
-
创建你的第一个 Subagent:
/agents create按照引导向导创建专用代理。
-
管理现有代理:
/agents manage查看和管理已配置的 Subagent。
-
自动使用 Subagent:只需让主 AI 执行与你的 Subagent 专长匹配的任务。AI 会自动委派合适的工作。
使用示例
User: "Please write comprehensive tests for the authentication module"
AI: I'll delegate this to your testing specialist Subagents.
[Delegates to "testing-expert" Subagents]
[Shows real-time progress of test creation]
[Returns with completed test files and execution summary]`管理
CLI 命令
Subagent 通过 /agents 斜杠命令及其子命令进行管理:
用法:/agents create。通过分步引导向导创建新的 Subagent。
用法:/agents manage。打开交互式管理对话框,用于查看和管理现有 Subagent。
存储位置
Subagent 以 Markdown 文件形式存储在多个位置:
- 项目级:
.qwen/agents/(优先级最高) - 用户级:
~/.qwen/agents/(回退路径) - 扩展级:由已安装的扩展提供
这使你能够拥有项目专属代理、跨所有项目使用的个人代理,以及提供专项能力的扩展代理。
扩展 Subagent
扩展可以提供自定义 Subagent,在启用扩展时即可使用。这些代理存储在扩展的 agents/ 目录中,格式与个人和项目代理相同。
扩展 Subagent:
- 启用扩展时自动发现
- 在
/agents manage对话框的 “Extension Agents” 部分显示 - 无法直接编辑(需修改扩展源码)
- 遵循与用户定义代理相同的配置格式
要查看哪些扩展提供了 Subagent,请检查扩展的 qwen-extension.json 文件中的 agents 字段。
文件格式
Subagent 使用带有 YAML frontmatter 的 Markdown 文件进行配置。该格式易于阅读,且可使用任何文本编辑器轻松修改。
基本结构

System prompt content goes here.
Multiple paragraphs are supported.模型选择
使用可选的 model frontmatter 字段控制 Subagent 使用的模型:
inherit:使用与主对话相同的模型- 省略该字段:等同于
inherit glm-5:使用该模型 ID,并沿用主对话的认证类型openai:gpt-4o:使用其他提供商(从环境变量解析凭证)

自动委派
Qwen Code 会根据以下信息主动委派任务:
- 请求中的任务描述
- Subagent 配置中的
description字段 - 当前上下文和可用工具
若要鼓励更主动地使用 Subagent,可在 description 字段中加入 “use PROACTIVELY” 或 “MUST BE USED” 等短语。
