MH apple-reminders

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Apple Reminders helper, with disclosed reminder read/write/delete capabilities and no hidden execution or persistence behavior.

Install only if you are comfortable granting a third-party CLI access to Apple Reminders. For delete operations, ask the agent to show the target reminder or list first and confirm the exact item before using delete or --force.

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 force-delete command for reminders without any guidance to confirm user intent or warn about irreversible deletion. In an agent setting, this increases the chance of accidental data loss if the assistant translates ambiguous user requests into destructive actions.
