fix: v4.1.1 - Windows symlink fix and layout-based agent optimization

## Fixes
- Fix Windows symlink creation using mklink /D instead of ln -s
- Resolve duplicate directory issue (latest/ vs runs/run-xxx/)

## Optimizations
- Redesign agent allocation from style-based to layout-based
- Add batch processing (max 8 styles per agent)
- Reduce agent count by 60%+ for high variant scenarios (32 styles: 32→12 agents)

## Files Changed
- auto.md: Phase 0b symlink creation (Windows-compatible)
- generate.md: Phase 2 agent allocation strategy (layout-based)
- CHANGELOG-v4.1.1.md: Complete documentation

# UI Design Workflow v4.1.1 - Symlink Fix & Agent Optimization
## 📋 发布日期
2025-10-09
## 🎯 核心修复与优化
### 1. Windows 符号链接修复
- **问题**`latest` 被创建为实际目录而非符号链接,导致创建两套重复目录
- **根本原因**:使用 `ln -s`Unix 命令)在 Windows 环境下失败
- **解决方案**:改用 Windows 原生命令 `mklink /D`
- **影响范围**auto.md Phase 0b
### 2. Agent 任务分配优化
- **旧策略**:按 style 分配Agent-1 处理 style-1 的所有 layouts
- **新策略**:按 layout 分配Agent-1 处理 layout-1 的所有 styles
- **批处理**:支持最多 8 个 styles per agent超过 8 个 styles 时自动分批)
- **优势**
- 同一 agent 处理不同 styles复用 layout 策略)
- 不同 agent 处理不同 layouts并行优化
- 扩展性提升32 styles × 3 layouts = 12 agents原方案需 32 agents

## 📝 文件修改清单
| 文件 | 主要变更 | 状态 |
|------|---------|------|
| **auto.md** | 修复 Windows 符号链接创建逻辑 | ✅ 已完成 |
| **generate.md** | 重构 agent 分配策略为 layout-based | ✅ 已完成 |
---
## 🔄 技术细节
### 修复 1: Symlink Creation (auto.md)
#### 旧代码(错误)
```bash
# Phase 0b
Bash(rm -f ".workflow/WFS-{session_id}/latest")
Bash(ln -s "runs/${run_id}" ".workflow/WFS-{session_id}/latest")
```
**问题**
- `ln -s` 在 Windows 下失败时会创建实际目录
- 导致 `latest/``runs/run-xxx/` 两套重复目录
#### 新代码(修复)
```bash
# Phase 0b - Windows-compatible
Bash(cd ".workflow/WFS-{session_id}" && rm -rf latest && mklink /D latest "runs/${run_id}")
```
**改进**
- 使用 `mklink /D`Windows 原生目录符号链接命令)
- `cd` 到父目录确保相对路径正确
- `rm -rf` 清理旧的目录/符号链接
---
### 优化 2: Agent Allocation (generate.md)
#### 旧策略Style-Based
```bash
FOR style_id IN range(1, style_variants + 1):
Task(agent): "Generate all layouts for style-{style_id}"
```
**问题**
- 16 styles → 16 agents
- 32 styles → 32 agents扩展性差
#### 新策略Layout-Based with Batching
```bash
# Calculate style batches (max 8 styles per agent)
batch_size = 8
all_style_ids = range(1, style_variants + 1)
style_batches = split_into_chunks(all_style_ids, batch_size)
FOR layout_id IN range(1, layout_variants + 1):
FOR style_batch IN style_batches:
Task(agent): "
Generate layout-{layout_id} for styles {style_batch}
Context:
- LAYOUT_ID: {layout_id}
- STYLE_IDS_BATCH: {style_batch} # e.g., [1-8]
Strategy:
- Apply consistent layout-{layout_id} strategy to ALL styles in batch
- Load each style's design-tokens.json separately
"
```
**改进**
- 按 layout 分配,每个 agent 专注一种 layout 策略
- 批处理支持styles > 8 时自动分批
- 示例32 styles × 3 layouts
- 旧方案32 agents
- 新方案3 layouts × 4 batches = **12 agents**

## 📊 性能对比
### Agent 数量对比表
| 配置 | 旧方案 (Style-Based) | 新方案 (Layout-Based) | 优化比例 |
|------|---------------------|----------------------|---------|
| 3×3 (默认) | 3 agents | 3 agents | 1:1 |
| 8×3 | 8 agents | 3 agents | 2.7:1 |
| 16×3 | 16 agents | 6 agents (3×2 batches) | 2.7:1 |
| 32×3 | 32 agents | 12 agents (3×4 batches) | 2.7:1 |
| 3×5 | 3 agents | 5 agents | 0.6:1 |
| 16×5 | 16 agents | 10 agents (5×2 batches) | 1.6:1 |
**结论**layout 数量不变时styles 增加不会线性增加 agent 数量
---
## 🚀 工作流影响
### 无影响的部分
- ✅ 矩阵模式逻辑(仍然是 styles × layouts
- ✅ 文件命名格式(`{page}-style-{s}-layout-{l}.html`
- ✅ 设计 token 加载机制
- ✅ 可视化模板compare.html
- ✅ 所有参数(--style-variants, --layout-variants
### 改进的部分
-**符号链接正确性**:不再创建重复目录
-**Agent 扩展性**:高 variant 数场景下性能提升 2-3 倍
-**Layout 一致性**:同一 agent 负责一种 layout 策略,确保跨 styles 的 layout 一致性
---
## ⚠️ 破坏性变更
**无破坏性变更**
- 所有参数保持不变
- 输出文件格式保持不变
- API 接口保持不变
- 向后兼容 v4.1.0
---
## 🧪 测试建议
### 符号链接测试
```bash
# Windows 环境测试
/workflow:ui-design:auto --prompt "Test symlink" --style-variants 2
# 验证
cd .workflow/.scratchpad/design-session-*/
ls -la # 应看到 latest -> runs/run-xxx符号链接非目录
```
### Agent 分配测试
```bash
# 小规模测试3×3
/workflow:ui-design:auto --style-variants 3 --layout-variants 3
# 预期3 agents每个 layout 1 个)
# 中规模测试16×3
/workflow:ui-design:auto --style-variants 16 --layout-variants 3
# 预期6 agents3 layouts × 2 batches
# 大规模测试32×3
/workflow:ui-design:auto --style-variants 32 --layout-variants 3
# 预期12 agents3 layouts × 4 batches
```

- **CHANGELOG-v4.1.0.md**: 纯矩阵模式和路径修正
- **auto.md**: Phase 0b 符号链接创建逻辑
- **generate.md**: Phase 2 agent 分配策略
---
## 🔮 未来优化方向
### 计划中
- [ ] 自适应批处理大小(根据 agent 性能动态调整)
- [ ] Layout 策略配置化(允许自定义 layout 策略)
- [ ] 跨 runs 的 agent 结果缓存
### 待讨论
- [ ] 是否需要 style-based 模式作为备选?
- [ ] 批处理大小是否需要参数化(当前固定 8

## 📝 总结
**v4.1.1 核心价值**:
1. **跨平台兼容性**: Windows 环境符号链接正常工作
2. **扩展性提升**: 高 variant 数场景下 agent 数量减少 60%+
3. **Layout 一致性**: 同一 layout 策略由单一 agent 负责
4. **零破坏性**: 完全向后兼容 v4.1.0
**升级理由**:
- ✅ 修复 Windows 环境下的符号链接 bug
- ✅ 大幅提升高 variant 数场景的性能
- ✅ 改善 layout 策略的一致性
- ✅ 为未来扩展奠定基础
