工作流程

Step 1: 解析库名 → 获取 Library ID

# 基础搜索
npx ctx7 library react

# 带自然语言查询（提高相关性）
npx ctx7 library react "How to clean up useEffect with async operations"
npx ctx7 library nextjs "How to set up app router with middleware"
npx ctx7 library prisma "How to define one-to-many relations"

# 输出 JSON 便于脚本处理
npx ctx7 library react --json | jq '.[0].id'

返回字段：

• Library ID — 格式 /org/project，传给 ctx7 docs
• Code Snippets — 索引的代码示例数量
• Source Reputation — High/Medium/Low/Unknown
