Security checks for vulnerabilities and agentic risk

Overview

This is a plain Markdown guidance skill for evaluating concept feasibility and shows no hidden execution, persistence, data access, or destructive behavior.

Before installing, note that the skill content is Chinese-language and oriented around concept validation reports. It appears safe from a security perspective, but users who need another language may want the publisher to clarify language preference handling.

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

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 93% confidence
Finding: The manifest description and the entire markdown body are written exclusively in Chinese, and the skill does not indicate that users may choose another language or that the Chinese-only scope is intentional for a region-specific use case. Under the language/locale policy, a skill should not implicitly force a specific language without user opt-in or clear justification.
Content: No source excerpt is available for this finding.
