Security checks for vulnerabilities and agentic risk

Overview

This is a simple creative-writing skill with no code execution, data access, persistence, or privileged behavior.

Before installing, users should know this skill is a prompt-only writing aid. The only notable issue is a small mixed-language phrase in the example, which may affect polish but does not create a security concern.

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

Findings (1)

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 88% confidence
Finding: The example output contains the Chinese text "mentor受伤" embedded in otherwise English content. This suggests the skill may produce non-English output without offering the user a language preference or documenting a locale-specific purpose, which conflicts with the language/locale policy criteria.
Content: No source excerpt is available for this finding.
