## CRITICAL: RESEARCH ONLY, NO IMPLEMENTATION

- **DO NOT** write any implementation code
- **DO NOT** make final technology decisions without user confirmation
- **ONLY** gather information, compare options, document constraints
- Present options objectively with pros/cons

## Purpose

执行问题域调研（External Research），研究外部技术、模式和最佳实践，为需求实现提供技术选型依据。

## Guardrails

- **MUST** read internal.md first to understand existing constraints
- **MANDATORY**: Use `mcp__grok-search` for external research
- **MUST** verify external recommendations against internal constraints
- All findings must include source URLs
- Prefer recent sources (2024-2025)

---

## Steps

### Step 0: Load Internal Research

```bash
# Read internal research for context
cat gudaspec/research/<requirement-id>/internal.md
```

Extract:
- Hard constraints (compatibility requirements)
- Existing technology stack
- Integration points
- Open questions that need external research

### Step 1: Identify Research Topics

Based on internal research triggers, identify specific research topics:

```
📋 External Research 议题

需求ID: <requirement-id>
基于内部研究，需要调研以下议题:

| ID | 议题 | 调研目的 | 与内部约束关系 |
|----|------|----------|----------------|
| ER-1 | <topic> | <purpose> | <constraint compatibility> |
| ER-2 | <topic> | <purpose> | <constraint compatibility> |

确认开始调研？
```

### Step 2: Execute External Research

For each research topic, use `mcp__grok-search`:

**Search Patterns**:
| 调研类型 | 搜索模式 |
|----------|----------|
| 技术对比 | `"[Tech A] vs [Tech B] [use case] 2024 2025"` |
| 最佳实践 | `"[Domain] best practices production 2025"` |
| 实现参考 | `"[Framework] [feature] implementation example"` |
| API限制 | `"[Service] API rate limits pricing 2025"` |
| 安全考量 | `"[Technology] security vulnerabilities CVE 2024"` |

### Step 3: Analyze Each Topic

For each topic, gather:
- Multiple options/approaches
- Pros and cons of each
- Compatibility with internal constraints
- Community adoption and maintenance status
- License considerations

### Step 4: Generate External Document

Create:
```
gudaspec/research/<requirement-id>/external.md
```

**Document Template**:

```markdown
---
requirement_id: <requirement-id>
created: <ISO timestamp>
researcher: claude
status: pending-review
type: external
internal_ref: gudaspec/research/<requirement-id>/internal.md
