AI Note Assistant

Security checks for vulnerabilities and agentic risk

Overview

This is a note-editing helper that only provides instructions for rewriting or answering about selected text, with no code execution, persistence, credential access, or hidden data flow.

Install this only in note-editing flows where edits are clearly scoped to a user selection and can be previewed or undone. Be careful with ambiguous prompts because the skill may return replacement text instead of an explanatory answer.

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
Vulnerability Patterns
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill is described for broad use in note editors and AI writing assistants without defining clear activation boundaries, increasing the chance it is invoked in contexts where silent text modification is inappropriate or unexpected. In an editor-integrated assistant, ambiguous triggering can cause unintended content changes or user confusion, especially when handling selected text automatically.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The top-level description markets seamless integration and silent replacement behavior but does not prominently warn that instruction mode may directly replace selected text without explanatory output. In a note-editing context, this increases the risk of users unintentionally invoking destructive edits and losing or altering content they expected only to discuss.

Vague Triggers

Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill says it 'automatically distinguishes two modes' but provides only high-level examples rather than deterministic rules, so ordinary requests may be misclassified as edit commands or questions. Because instruction mode outputs replacement text only, a misclassification can silently overwrite selected content without explanation or confirmation.
