Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Apple Notes helper, but users should understand it installs and relies on a third-party CLI with Apple Notes access.

Install only if you trust the memo CLI source, review the Homebrew tap or repository before installing, and grant Apple Notes Automation access only if you are comfortable letting this tool view and change your notes, including deletes through its interactive commands.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
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

Review package formulae, build scripts, and transitive dependencies before updating the pinned version. 7. Grant Notes.app Automation access only after installation integrity has been verified, and revoke the permission when it is no longer required. ]]>
