Security checks for vulnerabilities and agentic risk

Overview

This skill is a small local originality-checking CLI whose behavior matches its contest review purpose and does not show hidden persistence, credential access, or exfiltration.

Before installing, confirm the Chinese-language documentation fits your users and treat the checker as advisory only: it uses a simple illustrative hash-similarity algorithm and explicitly requires human review for final contest decisions.

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

Low
Confidence
85% confidence
Finding
The file presents the skill name, description, usage guidance, and warnings only in Chinese. The policy requires flagging language or locale constraints when a skill forces a specific language without user opt-in, and no alternative language option or justification is provided here.

Dynamic attribute access via getattr()

Confidence
50% confidence
Finding
Dynamic getattr() with a non-literal attribute name can access arbitrary object attributes, potentially bypassing access controls.
