Npjames Apple Reminders

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Apple Reminders CLI helper, though users should be careful with its delete examples.

Install only if you intend to let the agent operate on your Apple Reminders. Before any delete or list-delete command, ask the agent to show the matching reminder or list first and avoid force deletion unless you are certain of the target.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Finding
The skill documents a destructive command (`remindctl delete 4A83 --force`) without any caution, confirmation guidance, or recommendation to verify the target ID first. In an agent setting, users or downstream automation may copy this pattern directly, increasing the risk of unintended permanent deletion of reminders or lists of personal task data.
