Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent Markdown-to-HTML slide generator with local template assets and no evidence of hidden execution, persistence, credential access, or data exfiltration.

Install this if you want a Chinese-styled Markdown slide generator that creates standalone HTML. Review or adjust the language defaults if you need non-Chinese output, but the inspected files do not show security-impacting hidden behavior.

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: 94% confidence
Finding: The skill metadata and instructions are written to require Chinese-language behavior without indicating that the user may choose another language. This can override user preference, reduce accessibility, and cause unexpected behavior in multilingual environments, especially when the agent is expected to adapt to the user's language.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 88% confidence
Finding: This CSS file contains natural-language comments written exclusively in Chinese, such as at L002, L006, and L012, with no indication that another language is supported or that Chinese is intentionally required. Under the policy rule for language or locale constraints, this can be treated as a language-specific choice without user opt-in or documented justification.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 96% confidence
Finding: The HTML root element is hard-coded to lang="zh-CN", which imposes a specific language/locale. Under the policy, locale constraints should either be optional for the user or clearly justified as region-specific; neither is evident in this file.
Content: No source excerpt is available for this finding.
