Apple Reminders.Old

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Apple Reminders helper, but users should be careful with its documented delete commands.

Install only if you want an agent to manage your Apple Reminders through remindctl. Review delete and list-delete actions before approving them, because the skill documents destructive commands and does not itself require a confirmation step.

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

Missing User Warnings

Medium
Confidence
92% confidence
Finding
The skill documents a forceful delete command (`remindctl delete 4A83 --force`) without any warning, confirmation guidance, or emphasis on irreversible data loss. In an agent skill context, this increases the chance that an automated system or user will invoke deletion casually, causing unintended permanent removal of reminders or lists without an opportunity to recover.
