## Definition
后续 Agent通常是 Reviewer/QA 角色)对前序 Agent 的产出进行审查,生成具体改进建议,前序 Agent 根据反馈修改后再交付的迭代机制。
## Core Principle
反馈必须是**具体的、可执行的**,而非泛泛的评价。"CTA 按钮颜色对比度不够"比"设计不够好"有价值一万倍。
## Usage in The Agency
- [[workflow-landing-page]]Growth Hacker 审查 HTML 后给出具体修改意见 → Frontend Developer 15:30 前应用反馈并交付最终版本
- [[workflow-startup-mvp]]QA Auditor 检查第一版 → Dev 根据 Bug 报告修复 → Re-audit 循环直到达标
- [[support-analytics-reporter]]Analytics Reporter 生成报告 → 用户反馈 → 调整分析维度
## Structure
```
[Agent A 产出 v1] → [Reviewer Agent B 审查] → [具体改进建议]
↑ ↓
└──────────── [Agent A 修改后交付 v2] ←───────┘
```
## Key Requirements
1. **Reviewer 必须独立于 Creator**——自己评审自己的产出无效
2. **反馈必须有具体量化指标**——"降低 50ms 加载时间"比"优化性能"有用
3. **时间盒必须保护修改时间**——反馈没有时间完成修改等于无效
## Aliases
- Review-Iterate Cycle
- Quality Assurance Loop
- Iteration Cycle
