+export SKILL_SEARCH_KEY="your-api-key"  # 可选
+
+# 搜索
+python -m skill_search "python testing"
+
+# 限定类别
+python -m skill_search "docker deploy" --category devops
+
+# JSON 输出（适合程序集成）
+python -m skill_search "git workflow" --json
+
+# 查看环境信息
+python -m skill_search --env
+
+# 查看索引统计
+python -m skill_search --stats
+```
