<!-- GUDASPEC:RESEARCH:START -->

## CRITICAL: DOCUMENT ONLY, NO SUGGESTIONS

- **DO NOT** suggest improvements or changes
- **DO NOT** critique implementation or identify problems
- **DO NOT** recommend refactoring or optimizations
- **ONLY** describe: what exists, where it exists, how components interact
- You are creating a **technical map** of constraints, not a roadmap for changes

## Purpose

执行代码域调研（Internal Research），分析现有代码库约束，生成需求ID和待审查的内部研究文档。

## Guardrails

- If project lacks `./openspec/` directory, prompt user to run `/gudaspec:init`.
- **MANDATORY**: Use `mcp__auggie-mcp__codebase-retrieval` to minimize grep/find operations.
- **NEVER** divide tasks by roles. **ALWAYS** divide by context boundaries.
- Base all judgments on code evidence. Speculation prohibited.
- All findings must include file:line references.

---

## Steps

### Step 0: Receive Requirement

When invoked, respond:

```
我已准备好进行代码域调研。请描述您的需求，我将：

1. 分析现有代码库中的相关约束
2. 生成需求ID便于后续管理
3. 输出待审查的内部研究文档

请描述您的需求：
```

Wait for user input.

### Step 1: Generate Requirement ID

Based on user's requirement description, generate a kebab-case ID:

**命名规范**（参考OpenSpec）：
- 格式: `<action>-<target>[-<scope>]`
- 动作词: `add`, `fix`, `update`, `remove`, `refactor`, `migrate`
- 全小写，单词间用连字符
- 长度: 3-5个单词
- 避免缩写，保持可读性

**示例**：
| 用户需求 | 生成的需求ID |
|----------|--------------|
| "添加Outlook邮件前端" | `add-outlook-email-frontend` |
| "修复用户登录超时问题" | `fix-user-login-timeout` |
| "重构支付模块" | `refactor-payment-module` |
| "添加双因素认证" | `add-two-factor-auth` |
| "迁移数据库到PostgreSQL" | `migrate-database-postgresql` |

Confirm with user:
```
需求ID: <generated-id>
确认此ID或提供修改建议：
```

### Step 2: Read Mentioned Files

- If user mentions specific files, read them **FULLY** before proceeding
- This ensures complete context before decomposition

### Step 3: Codebase Assessment

Use `mcp__auggie-mcp__codebase-retrieval` to:
- Scan project structure
- Identify relevant modules/directories
- Determine context boundaries for parallel research

### Step 4: Define Context Boundaries

Divide by **context**, not roles:

| Correct (Context) | Incorrect (Role) |
|-------------------|------------------|
| User-related code | "架构师 agent" |
| Authentication layer | "安全专家 agent" |
| Data access layer | "DBA agent" |
| Target feature area | "领域专家 agent" |

### Step 5: Parallel Subagent Research

For each context boundary, spawn subagent:

```
You are a documentarian, NOT a critic.
Document what EXISTS, not what SHOULD BE.

Context: [boundary_name]
Scope: [directories/files]

Output JSON:
{
  "context_boundary": "string",
  "relevant_files": [{"path": "", "purpose": "", "key_exports": [], "lines": ""}],
  "existing_patterns": ["pattern - location"],
  "hard_constraints": ["constraint - file:line - reason"],
  "soft_constraints": ["convention - where observed"],
  "dependencies": {"internal": [], "external": []},
  "information_flow": "description",
  "integration_points": ["where new code must connect"],
  "open_questions": ["question - context"]
}
```

### Step 6: Aggregate and Generate Internal Document

Create directory and file:
```
gudaspec/research/<requirement-id>/internal.md
```

**Document Template**:

````markdown

requirement_id: <requirement-id>
created: <ISO timestamp>
researcher: claude
git_commit: <current commit>
branch: <current branch>
status: pending-review

## External Research 初步判断

基于以上内部研究，以下情况可能需要外部调研：

| 触发条件 | 检测结果 | 说明 |
|----------|----------|------|
| 引入新技术/库 | ⬜ 是 / ⬜ 否 | |
| 代码库无相关参考 | ⬜ 是 / ⬜ 否 | |
| 新架构模式 | ⬜ 是 / ⬜ 否 | |
| 未知领域知识 | ⬜ 是 / ⬜ 否 | |
| 用户显式要求 | ⬜ 是 / ⬜ 否 | |

初步建议: [ ] 需要 External Research / [ ] 不需要
