作为架构师，分析以下功能需求:

"${feature}"

请提供:
1. 技术方案概述
2. 需要的文件列表
3. Executor 任务描述
4. Reviewer 审查点

返回结构化 JSON:
{
  "approach": "技术方案概述",
  "files": ["预计需要的文件"],
  "executorTask": "详细任务描述",
  "reviewPoints": ["审查要点"]
}
  `, { schema: AnalysisSchema })

  // 指派 Executor Sub Agent
  const executorResult = await agent(`
作为后端开发专家，执行以下任务:

${analysis.executorTask}

技术要求:
- 使用项目现有代码风格
- 编写完整的单元测试
- 测试覆盖率 > 80%

完成后返回结构化 JSON:
{
  "files": ["修改的文件列表"],
  "tests": "测试结果",
  "changes": "主要改动说明",
  "status": "完成|部分完成|失败"
}
  `, {

  log(`📁 修改文件: ${executorResult.files.join(', ')}`)

  phase('代码审查')

  // 指派 Reviewer Sub Agent
  const reviewResult = await agent(`
作为代码审查专家，审查以下改动:

文件: ${executorResult.files.join(', ')}
改动: ${executorResult.changes}

审查要点:
${analysis.reviewPoints.map(p => `- ${p}`).join('\n')}

检查项目:
1. 代码质量和可读性
2. 测试覆盖是否充分
3. 是否有潜在的 bug
4. 安全性考虑
5. 性能影响

返回结构化 JSON:

  "severity": "low|medium|high|critical",
  "approval": true|false,
  "suggestions": ["改进建议"]
}
