invalid-data-cleaning skillA

invalid-data-cleaning is agent-read markdown (skill) from opensensenova/sensenova-skills: 用于大规模Excel数据的预处理，通过统计总行数判断是否转换为Parquet格式以提升读写效率，并使用正则表达式清洗指定文本列（如仅保留中文字符），最后导出清洗后的文件并提供下载链接。.

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

Latest version
mdr add opensensenova/sensenova-skills/invalid-data-cleaning@git:20260426.f0ab496
Exact content
mdr add opensensenova/sensenova-skills/invalid-data-cleaning@sha256:25a890b17ac40316

Pin 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.
