高等数学学情数据分析Skill

This skill appears to do what it says (student/class analytics) but the SKILL.md omits crucial operational and privacy details. Before installing or enabling it: 1) Ask the maintainer for the data connectors and exact data flow—where do assignment grades, timestamps, and student identifiers come from and what credentials are required? 2) Confirm how/where visualizations and exported data are hosted or uploaded (no placeholders like example.com in real use). 3) Require and verify privacy controls: data minimization, anonymization options, retention policy, and access controls, and ensure compliance with applicable student-data laws/policies. 4) If you must test, run it in an isolated environment with synthetic or anonymized data and audit network traffic to ensure no unexpected exfiltration. 5) Prefer skills with a visible source repo, maintainer contact, and documentation describing authentication and storage; lack of a homepage/source is an additional risk factor.
