Book Reviewer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrow writing assistant for Chinese literary book reviews and does not request unusual access or perform hidden actions.

Install this if you want Chinese literary book-review writing guidance, especially for WeChat-style articles. Users needing another language or publication format may need to explicitly ask the agent to adapt the output.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The manifest description and all user-facing instructions are written to prescribe a Chinese writing style and a WeChat-publication scenario, with no indication that other languages are supported on request. This is a natural-language locale policy issue because the skill imposes a specific language context without explicit user opt-in or documented justification.
Content: No source excerpt is available for this finding.
