Astock cache
磁盘缓存 + K线 parquet。当用户跑全市场筛选每次都要等 30 分钟时,Claude 应使用此 Skill。K线缓存到 ~/.astock_skills/cache/kline/ 目录,5 秒 vs 30 分钟,差 360 倍。From its SKILL.md

何时使用
- 全市场筛选太慢 (每次 30 分钟)
- 反复拉同一只股票 K 线
- 跑 screener 跑 2 遍
- 想要"盘后更新一次,白天用一天"
🚀 快速上手
# 看缓存多少了
python main.py kline-stats
# 跑一次全市场 K 线更新 (15-30 分钟, 但之后都是 5 秒)
python daily_update.py
# 单独看某只股票
python main.py kline-stats
# {"count": 5028, "size_mb": 18.4}

screener 集成示例
from skills.01-infra.astock-cache.main import kline_get_or_fetch
from skills.01-infra.astock-data-source.main import get_kline
def smart_kline(code, days=60):
"""优先读缓存, 缓存没有才拉网络"""
return kline_get_or_fetch(code, get_kline, days=days)
# 第一次慢 (拉网络), 之后 5 秒
df = smart_kline("601991", 60)
性能
| 场景 | 无缓存 | 有缓存 | 加速比 |
|---|---|---|---|
| 单股 60 日 K 线 | 1.2s | 0.05s | 24x |
| 全市场 5028 只 60 日 | 30min | 5s | 360x |
