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
- Use
get_schemafirst to inspect tables, fields, row counts, and source structure. - Use
get_table_detailwhen one table needs deeper field-level metadata. - Use
profile_datafor data quality, missingness, type, and distribution diagnostics. - Use
query_datafor small verification samples or targeted aggregates. - Use
generate_chartonly when a compact diagnostic chart materially helps explain the data.
