Install only if you are comfortable with a study coach that stores progress files locally, fetches learning-resource feeds, and can add cron reminders after you approve them.

Medium

Category: MCP Least Privilege
Confidence: 92% confidence
Finding: The skill documentation directs use of file I/O, network ingestion, and shell-backed scripts (for cron setup, persistence, and content fetching) but does not declare corresponding permissions. This creates a permission-model mismatch where reviewers or runtime policy may underestimate the skill’s actual capabilities, increasing the risk of unauthorized filesystem changes, scheduled task creation, or external data access.
