category-filtering-and-difficulty-analysis is agent-read markdown (skill) from opensensenova/sensenova-skills: 对Excel数据进行自定义分类统计、交叉分析与可视化，并基于多维度指标（如文本长度、术语密度、正则匹配等）进行综合评分与分级，适用于多类别数据分布统计及文本内容难度/质量评估场景。.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add opensensenova/sensenova-skills/category-filtering-and-difficulty-analysis@git:20260426.f0ab496mdr add opensensenova/sensenova-skills/category-filtering-and-difficulty-analysis@sha256:491f09cc2f98526fPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
