Security checks for vulnerabilities and agentic risk

Overview

This is a simple note-polishing skill that rewrites user-provided text and does not request system access, persistence, credentials, or external tools.

Before installing, understand that this skill may be selected for many rewrite or polishing requests, so avoid sending sensitive notes unless you want the agent to process them. No evidence shows hidden access, persistence, code execution, or data exfiltration.

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

5. Mark uncertainty instead of inventing details.
   If key information is missing, surface it as an open question or a neutral placeholder.

## Output Rules

- Keep the same language as the input unless the user requests another language.
- If the input mixes languages, normalize to the dominant language unless the user wants bilingual output.

Finding

The skill’s invocation description is very broad and overlaps with common, everyday rewriting requests such as polishing notes, emails, summaries, and announcements. In agent environments, this can cause over-triggering or unintended selection, leading the skill to process user content more often than necessary and increasing the chance that sensitive text is routed through it without clear user intent.
