Security audit

🎓 费曼学习法

Security checks across malware telemetry and agentic risk

Overview

This learning skill is educational and coherent, but it stores and reuses student learning responses and ratings without clear consent, retention, or deletion controls.

Review this carefully before installing for children or shared accounts. It should ideally disclose what student answers and learning ratings are saved, where they go, how long they remain, who can access them, and how a user or parent can delete them.

Vague Triggers

Medium
Confidence
89% confidence
Finding
The trigger phrases are broad enough that normal conversational statements like wanting to explain something or test understanding could activate the skill unintentionally. In an educational context this is not inherently malicious, but accidental activation can lead to unexpected state changes, persistence of student responses, and collection of learning data without a clearly intentional opt-in.

Missing User Warnings

Medium
Confidence
94% confidence
Finding
The workflow explicitly records student answers, evaluation grades, and writes back 'DNA' understanding data, but the document does not define any user-facing disclosure, consent, or retention controls. Because the skill is aimed at students, including minors, silent persistence of educational performance data creates meaningful privacy and compliance risk.

Missing User Warnings

Medium
Confidence
92% confidence
Finding
The pause/resume design persists the current state and student content, then reuses it in a later session without specifying a reminder that prior data was stored and is being surfaced again. This is risky because resumed sessions may reveal previously recorded student content to the user or another person using the same device/account without clear contextual notice.
