Apple Notes Formatting

Security checks for vulnerabilities and agentic risk

Overview

This is a formatting-only Apple Notes skill with no code execution, data access, persistence, or hidden behavior.

Install this if you want opinionated Apple Notes formatting, especially for Chinese notes. Be aware it may answer in Chinese by default and may apply Apple Notes-style structure to general note-cleanup requests unless you specify another format or language.

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

Findings (3)

Natural-Language Policy Violations

Medium

Confidence: 93% confidence
Finding: The instruction '默认用中文写' sets a specific language requirement for outputs. Under the policy criteria, forcing a language or locale without offering the user a choice is a natural-language policy violation.

Vague Triggers

Medium

Confidence: 94% confidence
Finding: The trigger text is broad enough to capture generic note-organizing or formatting requests, which can cause the skill to activate when the user did not specifically ask for Apple Notes-style output. This can lead to unintended instruction takeover, narrowing user choice and applying opinionated formatting rules in contexts where they are not appropriate.

Natural-Language Policy Violations

Medium

Confidence: 88% confidence
Finding: The description explicitly emphasizes handling long Chinese notes and the document itself is written entirely in Chinese, which can bias the skill toward a specific language/locale without confirming the user's preference. In practice, this may override user language expectations, degrade usability, and create misleading outputs when the surrounding conversation is in another language.
