Security checks for vulnerabilities and agentic risk

Overview

This is a small Markdown-only skill with static Chinese-language sector-priority commentary and no executable, persistence, credential, network, or file-access behavior.

Before installing, be aware that this skill is narrowly useful only if you want Chinese-language market-sector priority commentary. Its metadata should be clearer, and its investment-related statements should be treated as static commentary rather than current financial advice.

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
88% confidence
Finding

The title, description, and all user-facing content are presented only in Chinese, with no indication that the skill is region-specific or that users can choose another language. This can violate language/locale policy when a skill implicitly forces a specific language without opt-in or documented justification.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

This is a manifest/markdown-scoped file, so trigger clarity applies. The description field contains only the generic term '优先级' ('priority'), which does not specify the skill's domain, intended use case, or activation boundaries, making invocation conditions ambiguous and potentially broad.
