带普通用户把 Excel、CSV 或表格问题转成可复核的数据分析。用于第一次做数据清洗、描述统计、分组比较、趋势、异常检查、图表和结论汇报时；必须先明确业务问题、字段含义、时间范围与统计口径，再检查数据质量并生成可重复步骤，不把相关性写成因果，也不根据缺失数据编造结论。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

How to install
mdr add philrobinluo/ai-coevolution-skills/lls-ai-data-analysis-starter@sha256:6d02cefe38d351a1The line at the top of this page pins the label git:20260728.7cf7926, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
