1. Define 3 scenarios with progressive difficulty

1. Define 3 scenarios with progressive difficulty

scenarios = [ {"name": "simple", "complexity": 1.0, "input_size": 10}, {"name": "medium", "complexity": 3.0, "input_size": 50}, {"name": "complex", "complexity": 8.0, "input_size": 200}, ]
scenarios = [ {"name": "simple", "complexity": 1.0, "input_size": 10}, {"name": "medium", "complexity": 3.0, "input_size": 50}, {"name": "complex", "complexity": 8.0, "input_size": 200}, ]

Key Components

核心组件

  1. Coordinator - Spawns and monitors 3 instances
  2. State Manager - Tracks progress per scenario
  3. Aggregator - Merges results, extracts patterns
  1. Coordinator（协调器） - 生成并监控3个Skill实例
  2. State Manager（状态管理器） - 跟踪每个场景的进度
  3. Aggregator（聚合器） - 合并结果，提取规律

Key Decisions

关键决策

DecisionRecommendation
Synchronization modeFree-running with checkpoints
Scenario countAlways 3: simple, medium, complex
Input scaling1x, 3x, 8x (exponential)
Time budgets30s, 90s, 300s
Checkpoint frequencyEvery milestone + completion
决策项推荐方案
同步模式带检查点的自由运行模式
场景数量固定为3个：简单、中等、复杂
输入规模缩放1倍、3倍、8倍（指数级）
时间预算30秒、90秒、300秒
检查点频率每个里程碑节点+完成时

Common Mistakes

常见误区

  • Sequential instead of parallel: Defeats purpose. Always fan-out.
  • No synchronization: Results appear disjointed.
  • Unclear difficulty scaling: Differ in scale, not approach.
  • Missing aggregation: Individual results lack comparative insights.
  • 串行而非并行执行：违背设计初衷，必须采用扇出模式。
  • 未设置同步机制：结果显得零散无关联。
  • 难度缩放不清晰：仅在规模上差异，而非处理方式。
  • 缺少聚合步骤：单独结果无法提供对比洞察。
