kazuki e799c35efd refactor: migrate to clean architecture with src/ layout
## Migration Summary
- Moved from flat `superclaude/` to `src/superclaude/` (PEP 517/518)
- Deleted old structure (119 files removed)
- Added new structure with clean architecture layers

## Project Structure Changes
- OLD: `superclaude/{agents,commands,modes,framework}/`
- NEW: `src/superclaude/{cli,execution,pm_agent}/`

## Build System Updates
- Switched: setuptools → hatchling (modern, PEP 517)
- Updated: pyproject.toml with proper entry points
- Added: pytest plugin auto-discovery
- Version: 4.1.6 → 0.4.0 (clean slate)

## Makefile Enhancements
- Removed: `superclaude install` calls (deprecated)
- Added: `make verify` - Phase 1 installation verification
- Added: `make test-plugin` - pytest plugin loading test
- Added: `make doctor` - health check command

## Documentation Added
- docs/architecture/ - 7 architecture docs
- docs/research/python_src_layout_research_20251021.md
- docs/PR_STRATEGY.md

## Migration Phases
- Phase 1: Core installation  (this commit)
- Phase 2: Lazy loading + Skills system (next)
- Phase 3: PM Agent meta-layer (future)

# PM Agent: Upstream vs Clean Architecture Comparison
**Date**: 2025-10-21
**Purpose**: 本家Upstreamと今回のクリーンアーキテクチャでのPM Agent実装の違い
---
## 🎯 概要
### Upstream (本家) - Skills型PM Agent
**場所**: `~/.claude/skills/pm/` にインストール
**形式**: Markdown skill + Python init hooks
**読み込み**: Claude Codeが起動時に全Skills読み込み
### This PR - Core型PM Agent
**場所**: `src/superclaude/pm_agent/` Pythonパッケージ
**形式**: Pure Python modules
**読み込み**: pytest実行時のみ、import必要分だけ

## 🔄 機能比較
### 1. Session Start Protocol
#### Upstream (本家)
```yaml
Trigger: EVERY session start (自動)
Method: pm_init/init_hook.py
Actions:
1. PARALLEL Read:
- docs/memory/pm_context.md
- docs/memory/last_session.md
- docs/memory/next_actions.md
- docs/memory/current_plan.json
2. Confidence Check (200 tokens)
3. Output: 🟢 [branch] | [n]M [n]D | [token]%
Token Cost: ~8K (memory files) + 200 (confidence)
```
#### This PR
```python
# 自動実行なし - 手動で呼び出し
from superclaude.pm_agent.confidence import ConfidenceChecker
checker = ConfidenceChecker()
confidence = checker.assess(context)
Token Cost: ~2K (confidence moduleのみ)
```
**差分**:
- ❌ 自動実行なし
- ✅ トークン消費 8.2K → 2K (75%削減)
- ✅ オンデマンド実行
---
### 2. Pre-Execution Confidence Check
#### Upstream (本家)
```markdown
# superclaude/agents/pm-agent.md より
Confidence Check (200 tokens):
❓ "全ファイル読めた?"
❓ "コンテキストに矛盾ない?"
❓ "次のアクション実行に十分な情報?"
Output: Markdown形式
Location: Agent definition内
```
#### This PR
```python
# src/superclaude/pm_agent/confidence.py
class ConfidenceChecker:
def assess(self, context: Dict[str, Any]) -> float:
"""
Assess confidence (0.0-1.0)
Checks:
1. Documentation verified? (40%)
2. Patterns identified? (30%)
3. Implementation clear? (30%)
Budget: 100-200 tokens
"""
# Python実装
return confidence_score
```
**差分**:
- ✅ Python関数として実装
- ✅ テスト可能18 tests
- ✅ Pytest fixture利用可能
- ✅ 型安全
- ❌ Markdown定義なし
---
### 3. Post-Implementation Self-Check
#### Upstream (本家)
```yaml

Self-Evaluation Checklist:
- [ ] Did I follow architecture patterns?
- [ ] Did I read documentation first?
- [ ] Did I check existing implementations?
- [ ] Are all tasks complete?
- [ ] What mistakes did I make?
- [ ] What did I learn?
Token Budget:
Simple: 200 tokens
Medium: 1,000 tokens
Complex: 2,500 tokens
Output: docs/pdca/[feature]/check.md
```
#### This PR
```python
# src/superclaude/pm_agent/self_check.py
class SelfCheckProtocol:
def validate(self, implementation: Dict[str, Any])
-> Tuple[bool, List[str]]:
"""
Four Questions Protocol:
1. All tests pass?
2. Requirements met?
3. Assumptions verified?
4. Evidence exists?
7 Hallucination Red Flags detection
Returns: (passed, issues)
"""
# Python実装
```
**差分**:
- ✅ プログラマティックに実行可能
- ✅ 16 tests完備
- ✅ Hallucination detection実装
- ❌ PDCA docs自動生成なし
---
### 4. Reflexion (Error Learning)
#### Upstream (本家)
```python
# superclaude/core/pm_init/reflexion_memory.py
class ReflexionMemory:
"""
Error learning with dual storage:
1. Local JSONL: docs/memory/solutions_learned.jsonl
2. Mindbase: Semantic search (if available)
Lookup: mindbase → grep fallback
"""
```
#### This PR
```python
# src/superclaude/pm_agent/reflexion.py
class ReflexionPattern:
"""
Same dual storage strategy:
1. Local JSONL: docs/memory/solutions_learned.jsonl
2. Mindbase: Semantic search (optional)
Methods:
- get_solution(error_info) → past solution lookup
- record_error(error_info) → save to memory
- get_statistics() → recurrence rate
"""
```
**差分**:
- ✅ 同じアルゴリズム
- ✅ 16 tests追加
- ✅ Mindbase optional化
- ✅ Statistics追加
---
### 5. Token Budget Management
#### Upstream (本家)
```yaml
# agents/pm-agent.md より
Token Budget (Complexity-Based):
Simple Task (typo): 200 tokens
Medium Task (bug): 1,000 tokens
Complex Task (feature): 2,500 tokens
Implementation: Markdown定義のみ
Enforcement: 手動
```
#### This PR
```python
# src/superclaude/pm_agent/token_budget.py
class TokenBudgetManager:
BUDGETS = {
"simple": 200,
"medium": 1000,
"complex": 2500,
}
def use(self, tokens: int) -> bool:
"""Track usage"""
@property
def remaining(self) -> int:
"""Get remaining budget"""
def get_recommendation(self) -> str:
"""Suggest optimization"""
```
**差分**:

## 📊 トークン消費比較
### シナリオ: PM Agent利用時
| フェーズ | Upstream | This PR | 削減 |
|---------|----------|---------|------|
| **Session Start** | 8.2K tokens (auto) | 0K (manual) | -8.2K |
| **Confidence Check** | 0.2K (included) | 2K (on-demand) | +1.8K |
| **Self-Check** | 1-2.5K (depends) | 1-2.5K (same) | 0K |
| **Reflexion** | 3K (full MD) | 3K (Python) | 0K |
| **Token Budget** | 0K (manual) | 0.5K (tracking) | +0.5K |
| **Total (typical)** | **12.4K tokens** | **6K tokens** | **-6.4K (52%)** |
**Key Point**: Session start自動実行がない分、大幅削減
---
## ✅ 維持される機能
| 機能 | Upstream | This PR | Status |
|------|----------|---------|--------|
| Pre-execution confidence | ✅ | ✅ | **維持** |
| Post-implementation validation | ✅ | ✅ | **維持** |
| Error learning (Reflexion) | ✅ | ✅ | **維持** |
| Token budget allocation | ✅ | ✅ | **維持** |
| Dual storage (JSONL + Mindbase) | ✅ | ✅ | **維持** |
| Hallucination detection | ✅ | ✅ | **維持** |
| Test coverage | Partial | 79 tests | **改善** |
---
## ⚠️ 削除される機能
### 1. Auto-Activation (Session Start)
**Upstream**:
```yaml
EVERY session start:
- Auto-read memory files
- Auto-restore context
- Auto-output status
```
**This PR**:
```python
# Manual activation required
from superclaude.pm_agent.confidence import ConfidenceChecker
checker = ConfidenceChecker()
```
**影響**: ユーザーが明示的に呼び出す必要あり
**代替案**: Skillsシステムで実装可能
---
### 2. PDCA Cycle Documentation
**Upstream**:
```yaml
Auto-generate:
- docs/pdca/[feature]/plan.md
- docs/pdca/[feature]/do.md
- docs/pdca/[feature]/check.md
- docs/pdca/[feature]/act.md
```
**This PR**:
```python
# なし - ユーザーが手動で記録
```
**影響**: 自動ドキュメント生成なし
**代替案**: Skillsとして実装可能
---
### 3. Task Management Workflow
**Upstream**:
```yaml
# workflows/task-management.md
- TodoWrite auto-tracking
- Progress checkpoints
- Session continuity
```
**This PR**:
```python
# TodoWriteはClaude Codeネイティブツールとして利用可能
# PM Agent特有のワークフローなし
```
**影響**: PM Agent統合ワークフローなし
**代替案**: pytest + TodoWriteで実現可能
---
## 🎯 移行パス
### ユーザーが本家PM Agentの機能を使いたい場合
**Option 1: Skillsとして併用**
```bash
# Core PM Agent (This PR) - always installed
pip install -e .
# Skills PM Agent (Upstream) - optional
superclaude install-skill pm-agent
```
**Result**:
- Pytest fixtures: `src/superclaude/pm_agent/`
- Auto-activation: `~/.claude/skills/pm/`
- **両方利用可能**
---
**Option 2: Skills完全移行**
```bash
# 本家Skills版のみ使用
superclaude install-skill pm-agent
# Pytest fixturesは使わない
```
**Result**:
- Upstream互換100%
- トークン消費は本家と同じ
---
**Option 3: Coreのみ推奨**
```bash
# This PRのみ
pip install -e .
# Skillsなし
```
**Result**:
- 最小トークン消費
- Pytest integration最適化
- Auto-activation なし
---
## 💡 推奨アプローチ
### プロジェクト用途別
**1. ライブラリ開発者 (pytest重視)**
**Option 3: Core のみ**
- Pytest fixtures活用
- テスト駆動開発
- トークン最小化
**2. Claude Code パワーユーザー (自動化重視)**
**Option 1: 併用**
- Auto-activation活用
- PDCA docs自動生成
- Pytest fixturesも利用
**3. 本家互換性重視**
**Option 2: Skills のみ**
- 100% Upstream互換
- 既存ワークフロー維持
