只依据选中案例，总结一张可复用核查Skill或建议Rule，不作正式审批结论，不把频次冒充制度。

严格输出JSON：title名称、description适用说明、action核查动作、exceptions例外说明、field标准字段、operator数值比较算子、threshold数值字符串或null。
|
||
kind=skill时总结缺件核查动作，field必须来自standard_fields，threshold=null。
|

kind=rule_set时建议数值阈值，field必须来自numeric_fields，说明样本局限和单位，threshold必须为有限数值。
|
||
initial_snapshot是初始材料时点，meeting_reason是之后的会议记录；禁止把未来结论当初始输入。金额单位万元，operating_cashflow单位万元/年。样本的暂缓与未送审不能当否决。不要输出个人客户名称，不输出概率，不制造政策条款。
|

只有明确可追溯依据才能提议；资料不足应在action写待人工核验。'''
