## 故障排除
### 子智能体未被调用
**问题**：主智能体试图自己做工作而不是委派。
**解决方案**：
1. **使描述更具体：**
```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
// 好
{ name: "research-specialist", description: "Conducts in-depth research on specific topics using web search. Use when you need detailed information that requires multiple searches." }
// 差
{ name: "helper", description: "helps with stuff" }
```
2. **指示主智能体进行委派：**
```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
const agent = createDeepAgent({
systemPrompt: `...your instructions...
IMPORTANT: For complex tasks, delegate to your subagents using the task() tool.
This keeps your context clean and improves results.`,
subagents: [...]
});
```
### 上下文仍然膨胀
**问题**：尽管使用了子智能体，上下文仍然填满。
**解决方案**：
1. **指示子智能体返回简洁结果：**
```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
systemPrompt: `...
IMPORTANT: Return only the essential summary.
Do NOT include raw data, intermediate search results, or detailed tool outputs.
Your response should be under 500 words.`
```
2. **对大数据使用文件系统：**
```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
systemPrompt: `When you gather large amounts of data:
1. Save raw data to /data/raw_results.txt
2. Process and analyze the data
3. Return only the analysis summary
This keeps context clean.`
```
### 选择了错误的子智能体
**问题**：主智能体为任务调用了不适当的子智能体。
**解决方案**：在描述中清晰区分子智能体：
```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
const subagents = [
{
name: "quick-researcher",
description: "For simple, quick research questions that need 1-2 searches. Use when you need basic facts or definitions.",
},
{
name: "deep-researcher",
description: "For complex, in-depth research requiring multiple searches, synthesis, and analysis. Use for comprehensive reports.",
}
];
```

## 结构化输出
子智能体支持[结构化输出](/oss/javascript/langchain/structured-output)，因此父智能体接收的是可预测、可解析的 JSON，而非自由格式文本。
