# Claude Code Workflow Analysis & Clauxton Integration Strategy

**Date**: 2025-10-20
**Purpose**: Validate typical Claude Code development workflows and determine optimal Clauxton integration
**Status**: Research Phase

---

## 1. Research Question

> "When building apps with Claude Code, does the typical flow go:
> Vague request → Requirements → Design docs (MD) → Implementation following those docs?"

**Goal**: Understand actual Claude Code workflows to design Clauxton features that fit naturally.

---

## 2. Typical Claude Code Workflows (Hypothesis)

### Scenario A: "Greenfield Project" (New App from Scratch)

#### Traditional Approach (Without Clauxton)
```
Step 1: Initial Request
User: "Todoアプリを作りたい"

Step 2: Claude Code Generates Requirements
Claude: "了解しました.以下の要件で進めます: 
- FastAPI + React
- JWT認証
- PostgreSQL
..."

Step 3: Claude Starts Coding Immediately
Claude:
  Write backend/main.py
  Write backend/models.py
  Write frontend/App.tsx
  ...

Problem:
❌ 要件が散逸(チャット履歴に埋もれる)
❌ 設計書なし(後から参照できない)
❌ Claude Codeは前のセッションを覚えていない
❌ チーム共有できない
```

#### Current Best Practice (With Manual Documentation)
```
Step 1: Initial Request
User: "Todoアプリを作りたい"

Step 2: Requirements Document
User: "まず要件定義書を docs/requirements.md に書いて"
Claude: ✓ Creates docs/requirements.md

Step 3: Architecture Design
User: "次にアーキテクチャ設計を docs/architecture.md に書いて"
Claude: ✓ Creates docs/architecture.md

Step 4: Task Breakdown
User: "タスクを docs/tasks.md にリストアップして"
Claude: ✓ Creates docs/tasks.md (but just markdown, not structured)

Step 5: Implementation
User: "では docs/tasks.md の最初のタスクから実装して"
Claude: Reads docs/tasks.md → Implements Task 1

Problem:
⚠️ 手動でドキュメント作成を指示する必要がある
⚠️ タスクは単なるMarkdown(構造化されていない)
⚠️ タスクの進捗管理が手動
⚠️ 競合検出なし
```

---

### Scenario B: "Feature Addition" (Existing Project)

#### Without Clauxton
```
Step 1: Feature Request
User: "ユーザー認証機能を追加して"

Step 2: Claude Code Investigates
Claude:
  - Reads existing code
  - Understands current architecture
  - BUT: No persistent context about past decisions

Step 3: Implementation
Claude: Starts implementing...

Problem:
❌ Past decisions not documented (e.g., "Why did we choose JWT?")
❌ No task breakdown
❌ Claude might make inconsistent choices
```

#### With Manual Documentation (Best Practice)
```
Step 1: Feature Request
User: "ユーザー認証機能を追加して"

Step 2: Claude Reads Existing Docs
Claude:
  - Reads docs/architecture.md
  - Reads docs/decisions.md
  - Understands context ✓

Step 3: Design & Task Breakdown
User: "認証機能の設計とタスクを docs/auth-design.md に書いて"
Claude: ✓ Creates docs/auth-design.md

Step 4: Implementation
Claude: Follows docs/auth-design.md

Better, but still:
⚠️ Manual documentation creation
⚠️ No structured task management
```

---

## 3. Observed Patterns

### Pattern 1: Documentation-Driven Development
**Reality**: Experienced developers DO create docs first with Claude Code:
- `docs/requirements.md` - What to build
- `docs/architecture.md` - How to structure it
- `docs/api-design.md` - API specifications
- `docs/tasks.md` - Task list (but unstructured)

**Why**:
- Provides persistent context across sessions
- Enables team collaboration
- Makes Claude Code's suggestions more consistent

### Pattern 2: Iterative Refinement
**Reality**: Development is NOT linear:
```
1. Initial vague request
2. Claude proposes high-level design
3. User refines requirements
4. Claude updates design
5. User asks "What about authentication?"
6. Claude adds auth design
7. Repeat...
```

**Key Insight**: Requirements and design evolve through conversation.

### Pattern 3: Context Loss Problem
**Reality**: Claude Code forgets:
- Why certain decisions were made
- What alternatives were considered
- What constraints exist
- What the overall plan is

**Current Workaround**:
- Put everything in markdown docs
- Tell Claude to "read docs/architecture.md" frequently

---

## 4. Where Clauxton Fits In

### 4.1 Current Clauxton Approach (v0.9.0-beta)

```
# Manual Knowledge Base registration
User: "FastAPIを使う理由をKBに登録して"
User: clauxton kb add --title "FastAPI選定理由" --category decision ...

# Manual Task registration
User: clauxton task add --name "JWT認証実装" ...
```

**Problem**: Too manual, doesn't fit natural Claude Code flow

---

### 4.2 Ideal Integration (Proposed)

#### Vision: Clauxton as "Intelligent Documentation Backend"

Instead of:
```
User → Claude → docs/requirements.md (unstructured)
User → Claude → docs/tasks.md (unstructured)
```

Should be:
```
User → Claude → Clauxton KB (structured)
User → Claude → Clauxton Tasks (structured)
             ↓
          Auto-generates docs/requirements.md for human reading
```

---

## 5. Proposed Workflow Integration

### 5.1 Greenfield Project with Clauxton

```
Step 1: Initial Request
User: "Todoアプリを作りたい"

Step 2: Requirements Gathering (Interactive)
Claude: "以下の要件でよろしいですか?
- バックエンド: FastAPI
- フロントエンド: React + TypeScript
- データベース: PostgreSQL
- 認証: JWT
..."

User: "はい, それでお願いします"

Step 3: Claude Auto-Registers to Clauxton KB ✨
Claude (internally):
  kb_add(title="FastAPI採用", category="architecture", content="...")
  kb_add(title="PostgreSQL選定", category="decision", content="...")
  kb_add(title="JWT認証方式", category="decision", content="...")

Step 4: Task Breakdown ✨
Claude: "タスクを分解しました: 
1. FastAPI初期化
2. DB接続設定
3. ユーザーモデル作成
..."

Claude (internally):
  task_import_yaml(yaml_content="""
  tasks:
    - name: "FastAPI初期化"
      priority: high
      files: [backend/main.py]
    ...
  """)

Step 5: Documentation Export (Optional) ✨
Claude: docs/requirements.md を生成(Clauxton KBから)
Claude: docs/tasks.md を生成(Clauxton Tasksから)

Step 6: Implementation
Claude: "TASK-001から始めます"
Claude (internally): task_get("TASK-001") → reads requirements
Claude: Implements...
Claude (internally): task_update("TASK-001", status="completed")
```

**Key Benefits**:
✅ Claude Code naturally integrates Clauxton into conversation
✅ Context is structured and persistent
✅ Human-readable docs are auto-generated
✅ No manual KB/Task registration needed

---

### 5.2 Feature Addition with Clauxton

```
Step 1: Feature Request
User: "ユーザー認証機能を追加して"

Step 2: Claude Searches Existing Context ✨
Claude (internally):
  kb_search("認証") → Finds "JWT認証方式" decision
  kb_search("FastAPI") → Understands backend stack

Claude: "既存の設計では JWT 認証を採用していますね.
これに従って実装します..."

Step 3: Design & Task Generation ✨
Claude (internally):
  kb_add(title="認証エンドポイント設計", ...)
  task_import_yaml(...)

Step 4: Conflict Detection ✨
Claude (internally):
  detect_conflicts("TASK-005") → "⚠️ backend/models/user.py は TASK-003 で編集中"

Claude: "注意: backend/models/user.py は別のタスクで編集中です.
先に TASK-003 を完了させますか?"

Step 5: Implementation
Claude: Implements following existing architecture ✓
```

---

## 6. Key Integration Points

### 6.1 Natural Language → Structured Data

**Current**: User manually runs `clauxton kb add`
**Proposed**: Claude Code extracts decisions from conversation and auto-registers

Example conversation:
```
User: "FastAPIを使いたい.理由は非同期処理が必要だから"

Claude (internally):
  Detects: Architecture decision
  Extracts: Technology=FastAPI, Reason=非同期処理
  Auto-registers: kb_add(
    title="FastAPI採用",
    category="architecture",
    content="非同期処理が必要なため, FastAPIを採用....",
    tags=["backend", "fastapi", "async"]
  )

Claude (to user): "了解しました.FastAPIで進めます."
```

**How**: Claude Code uses Clauxton MCP tools automatically

---

### 6.2 Conversational Task Breakdown

**Current**: User manually runs `clauxton task add` 10 times
**Proposed**: Claude Code generates tasks from conversation

Example:
```
User: "認証機能を実装して"

Claude: "認証機能を以下のタスクに分解しました: 
1. ユーザーモデル作成 (2h)
2. JWT生成ユーティリティ (1h)
3. ログインエンドポイント (3h)
4. トークン検証ミドルウェア (2h)

実装を開始してよろしいですか?"

User: "はい"

Claude (internally):
  task_import_yaml(yaml_content="""
  tasks:
    - name: "ユーザーモデル作成"
      priority: high
      files: [backend/models/user.py]
      estimate: 2
    ...
  """)
```

---

### 6.3 Auto-Generated Documentation

**Proposed**: Clauxton data → Human-readable docs

```
# After KB and Tasks are populated via conversation...

User: "ドキュメントを生成して"

Claude (internally):
  kb_entries = kb_list()
  tasks = task_list()

  Generates:
    docs/requirements.md (from KB: decisions + constraints)
    docs/architecture.md (from KB: architecture + patterns)
    docs/tasks.md (from Tasks)
    docs/api-design.md (from KB: pattern entries)
```

**Why**:
- Clauxton = source of truth (structured)
- Markdown docs = human-friendly view
- Best of both worlds

---

## 7. Missing Features for Ideal Integration

### 7.1 YAML Import (Already Proposed)
**Status**: Design document created (`BATCH_TASK_IMPORT.md`)
**Priority**: HIGH
**Why**: Enables Claude Code to generate tasks efficiently

### 7.2 Document Generation from KB
**Status**: NEW proposal
**Priority**: MEDIUM
**Feature**: `clauxton kb export docs/`

```bash
# Export KB entries to markdown docs
clauxton kb export docs/ --format=requirements

# Generates:
#   docs/requirements.md (decisions + constraints)
#   docs/architecture.md (architecture patterns)
#   docs/conventions.md (coding conventions)
```

**MCP Tool**:
```python
@mcp.tool()
def kb_export_docs(
    output_dir: str,
    format: str = "requirements"  # requirements, architecture, full
) -> dict[str, Any]:
    """
    Generate human-readable documentation from Knowledge Base.

    Returns:
        Dictionary with generated file paths
    """
```

### 7.3 Task Export to Markdown
**Status**: NEW proposal
**Priority**: LOW (nice-to-have)
**Feature**: `clauxton task export docs/tasks.md`

```bash
# Export tasks to markdown
clauxton task export docs/tasks.md

# Generates:
# # Project Tasks
#
# ## High Priority
# - [ ] TASK-001: FastAPI初期化 (1h)
# - [ ] TASK-002: DB接続設定 (2h)
# ...
```

### 7.4 Conversational KB Registration (Future)
**Status**: Future enhancement
**Priority**: MEDIUM-HIGH
**Concept**: Claude Code auto-detects decisions in conversation

**Example**:
```
User: "認証はJWTにしよう.OAuth2は複雑すぎる"

Claude (internally):
  Detects decision: JWT authentication
  Extracts reasoning: OAuth2 complexity
  Auto-suggests:
    "この決定をKnowledge Baseに記録しますか?
     タイトル: JWT認証採用
     カテゴリ: decision
     理由: OAuth2の複雑性を避けるため"

User: "はい"

Claude: kb_add(...) ✓
```

**Challenge**: Requires Claude Code to understand when to persist context
**Solution**: Provide clear prompts in CLAUDE.md for when to use KB

---

## 8. Recommended Clauxton Enhancements

### Priority 1: YAML Task Import (HIGH)
**Why**: Enables efficient task generation from conversation
**Timeline**: v0.10.0 (next release)
**Effort**: 8 hours

### Priority 2: KB Export to Docs (MEDIUM)
**Why**: Bridges structured data ↔ human-readable docs
**Timeline**: v0.10.0 or v0.11.0
**Effort**: 4 hours

### Priority 3: Enhanced CLAUDE.md Guidance (HIGH)
**Why**: Teach Claude Code when/how to use Clauxton
**Timeline**: Immediate (documentation update)
**Effort**: 2 hours

**Example additions to CLAUDE.md**:
```markdown
## When to Use Clauxton Knowledge Base

### During Requirements Gathering
When user mentions:
- Technology choices ("FastAPIを使う") → kb_add(category="architecture")
- Constraints ("ユーザーは最大1000件まで") → kb_add(category="constraint")
- Design decisions ("JWTで認証する") → kb_add(category="decision")

### During Task Planning
After breaking down features into tasks:
- Use task_import_yaml() to register all tasks at once
- Check conflicts with detect_conflicts() before starting work

### Before Implementation
Always:
1. kb_search() to find relevant design decisions
2. task_next() to get recommended task
3. detect_conflicts() to check file conflicts
```

### Priority 4: Task Templates (MEDIUM)
**Why**: Accelerate common project setups
**Timeline**: v0.11.0
**Effort**: 4 hours (creating templates)

---

## 9. Validation: Does This Match Reality?

### Question 1: Do users actually create docs first?
**Answer**: YES, experienced developers do
- Evidence: Common pattern in Claude Code community
- Benefit: Persistent context across sessions

### Question 2: Is manual KB registration realistic?
**Answer**: NO, too manual for natural conversation flow
**Solution**:
- Claude Code should auto-register via MCP tools
- Enhanced CLAUDE.md guides when to persist

### Question 3: Will users adopt task import?
**Answer**: YES, if it's seamless
- Key: Claude Code generates YAML automatically
- User just sees: "タスクを登録しました" (transparent)

### Question 4: Is Clauxton better than plain markdown?
**Answer**: YES, for structured data
- KB entries: Searchable, categorized, tagged
- Tasks: Dependency tracking, conflict detection, priority
- Markdown: Human-readable view (auto-generated)
