Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed stock-screening helper that uses web research and local reading permissions without evidence of hidden execution, persistence, or data misuse.

Before installing, understand that the skill may search the web and fetch financial/news pages to support stock-screening results. Treat outputs as research assistance, not investment advice, and specify your preferred language if you do not want Chinese-language responses.

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
Confidence
95% confidence
Finding
The manifest description and goal are written as directives in Chinese and describe the skill behavior without offering any language or locale choice. Per the policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale constraint is justified, which is not documented here.

Natural-Language Policy Violations

Medium
Confidence
92% confidence
Finding
The description states the skill will screen stocks and output the candidate list in Chinese-language text, but it does not offer a language option or explain why Chinese is required. This creates a natural-language locale policy concern because the skill appears to impose a specific language without user opt-in.
