データ分析
lucid-skill
AI-native data analysis via natural language. Connect Excel, CSV, MySQL, PostgreSQL data sources and query with SQL. Use when: (1) user asks to query, analyze, or explore data ('查询数据', '数据分析', '帮我看下数据'), (2) user provides Excel/CSV files or database credentials for analysis, (3) user asks business questions about connected data ('哪个产品销量最高', 'how do orders and customers relate?'), (4) user wants to discover table relationships, JOINs, or business domains, (5) user wants semantic search across tables. NOT for: data modification (INSERT/UPDATE/DELETE/DROP are blocked — read-only queries only), ETL pipelines, or data ingestion beyond connecting sources.
