# db-source-health 源健康状态

查询各数据源的健康状态：

```bash
uv run python .claude/skills/db-source-health/scripts/health.py
```

输出 JSON：
```json
{
  "success": true,
  "sources": [
    {
      "source": "hacker_news",
      "last_success": "2026-02-19T...",
      "last_failure": null,
      "consecutive_failures": 0,
      "total_calls": 15,
      "total_failures": 1,
      "failure_rate": 0.067
    }
  ],
