数据诊断

先获取 schema 和必要样本,报告表规模、字段类型、缺失、重复、异常、时间范围和关键分布。区分事实、风险与建议,指出可直接分析的字段及需要用户确认的口径。

Tool routing

  1. Use get_schema first to inspect tables, fields, row counts, and source structure.
  2. Use get_table_detail when one table needs deeper field-level metadata.
  3. Use profile_data for data quality, missingness, type, and distribution diagnostics.
  4. Use query_data for small verification samples or targeted aggregates.
  5. Use generate_chart only when a compact diagnostic chart materially helps explain the data.
