Security checks for vulnerabilities and agentic risk

Overview

This is a narrowly scoped photography education skill with no code execution, data access, persistence, or hidden behavior.

Installers should know this skill is mainly useful for Chinese-language photography guidance. From a security perspective, it is low risk because it only provides instructional advice and does not run commands, access data, or change the environment.

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 (2)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
85% confidence
Finding

The skill content is predominantly written in Chinese and presents the operational instructions, headings, and execution guidance in Chinese without stating that the user may choose another language. This can violate a language/locale policy when the skill is used in broader contexts and does not explicitly offer language choice or opt-in.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

This JSON test file encodes prompts and required responses entirely in Chinese, and the expected behavior implicitly requires the skill to operate in Chinese. Under the policy, forcing a specific language without user choice or a documented regional justification is a natural-language policy violation.
