# 安装 SDK
cd plugin/plugin_core
pip install -e .

# 安装 tool 插件
cd plugin/sample_tool
pip install -e .

# 安装 workflow 插件
cd plugin/sample_workflow_with_tool
pip install -e .

# 运行
acg-sample-tool --input /path/to/files --output /path/to/output

1. acg-sample-tool 发现 job (entry_points)
2. 加载 job.yml
3. 加载引用的 stages (tool.scan, tool.read, tool.copy)
4. 从 entry_points 发现 stage handlers
5. 构建 DAG 并执行
