Security checks for vulnerabilities and agentic risk

Overview

This skill is a plain Markdown guide for time-cycle market analysis and does not request code execution, credentials, persistence, or broad system access.

Before installing, consider that the skill is educational trading-analysis guidance and not financial advice. Its main limitation is language clarity: it may steer responses toward Chinese unless the agent follows the user's language preference.

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 (1)

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 88% confidence
Finding: The document is predominantly written in Chinese and presents the skill content and execution guidance in that language, while not stating that the user may choose another language. This can violate a language/locale policy when a skill effectively defaults to a specific language without user opt-in.
Content: No source excerpt is available for this finding.
