Security checks for vulnerabilities and agentic risk

Overview

This skill is a static marketing-page template helper with no hidden execution, credential access, persistence, or privilege-seeking behavior found.

This appears safe to install from a security perspective. Before publishing pages generated from it, check testimonials, customer counts, guarantees, scarcity language, pricing, and legal links so the output does not make unsupported or noncompliant marketing claims.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
93% confidence
Finding

The template string TRUSTED BY 10,000+ [理想Customers] mixes English with Chinese text in a way that is not explained or presented as optional. This can violate language/locale policy expectations because the skill does not offer a user choice of language or justify the locale-specific content.

Natural-Language Policy Violations

Category
Not specified by scanner
Confidence
91% confidence
Finding

The phrase Money-back guarantee (时长) contains Chinese text for duration, but the skill otherwise presents itself in English and does not explain this locale choice. Without opt-in or justification, this is a natural-language policy issue under the language/locale rule.

Confidence

Finding

The document declares lang="en", which fixes the skill output to English. Under the stated policy, forcing a specific language without offering a choice or documenting a justified regional constraint is a natural-language policy violation.

Confidence
95% confidence
Finding

The HTML root element sets lang="en", which bakes an English-only locale into the template. Under the policy rule, forcing a specific language without user opt-in or a documented region-specific reason is a natural-language policy concern.
