用于基于AkShare数据的风险标签生成场景。适用于金融工作中的基础任务单元。
本 Skill 使用 AkShare 提供的 A 股市场数据接口进行风险标签打标，主要包括：
stock_zh_a_spot_em：A 股实时行情快照，用于获取最新价、涨跌幅、成交量、成交额、换手率、市盈率等基础指标。stock_zh_a_hist：A 股历史行情，用于计算近 N 日波动率、回撤、均线偏离、成交额均值等风险特征。stock_individual_info_em：个股基础信息（如股票简称、总市值等），用于补充个股静态属性。说明：不同 AkShare 版本的字段命名可能略有差异，脚本中已尽量兼容常见字段名，但建议在生产使用前结合实际环境验证一次。
本 Skill 面向 A 股股票池进行风险标签打标，输出每只股票的风险标签、风险分数和综合风险等级。
st_risk：证券简称包含 ST、*ST 等特殊处理标识。high_volatility_20d：近 20 个交易日年化波动率偏高。large_drawdown_60d：近 60 个交易日最大回撤较大。low_liquidity：近 20 个交易日平均成交额偏低，流动性不足。abnormal_turnover：最新换手率异常偏高。near_limit_down：最新单日跌幅接近跌停风险区间。penny_stock：股价过低，价格脆弱性更高。below_ma20：股价低于 20 日均线，短期趋势偏弱。脚本会为每只股票输出：
