## Definition
竞争饱和度评分0-100由 [[idea-reality-mcp]] 基于 GitHub 仓库数量、star 分布、Hacker News 讨论量、npm/PyPI/Product Hunt 数据计算得出。数值越高表示该赛道越拥挤。
## Decision Thresholds
| Score | Interpretation | Agent Action |
|-------|---------------|-------------|
| > 70 | 高竞争(红海) | STOP展示竞品 + stars询问用户是否继续/转型/放弃 |
| 30-70 | 中等竞争 | 展示竞品 + pivot_hints建议差异化角度 |
| < 30 | 低竞争(白海) | 直接构建,确认机会空间存在 |
## Core Value
- 基于**真实数据**repo counts、star distributions、HN volume而非 LLM 主观猜测
- 防止独立开发者在已被成熟产品占领的赛道中浪费生命
- 低分 = 真正的白海机会 = 单兵创业者最佳切入窗口
