老房改造不踩雷

Security checks for vulnerabilities and agentic risk

Overview

This is a Chinese old-home renovation advice skill with local reference files and no evidence of hidden code, persistence, data access, or unsafe execution.

Install this if you want Chinese-language renovation guidance for older homes and second-hand homes. Treat pricing, property-buying, school-district, structural, electrical, waterproofing, and safety claims as general educational advice; verify major decisions with qualified local professionals, inspectors, engineers, or legal/real-estate advisers.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The trigger list contains many broad, generic renovation phrases that are likely to appear in ordinary conversations, increasing the chance the skill activates outside a clearly intended user request. Over-broad activation can cause context hijacking or unintended response injection, especially when the skill imposes a strong expert persona and domain-specific instructions once invoked.

Description-Behavior Mismatch

Confidence

Finding

The manifest describes a skill focused on answering renovation questions for old homes, second-hand homes, and developer-finished homes, including demolition, utilities, costs, structure safety, and kitchen/bath refresh. The "买房避坑类" section instead catalogs articles about whether to buy certain property types and school-district-driven purchases, which shifts from renovation/remodeling guidance to property purchase decision content.

This markdown file contains user-facing natural language exclusively in Chinese and does not provide any opt-in, alternative language, or justification that it is intended only for a Chinese-speaking or region-specific audience.

Finding

The instructions require the assistant to speak in a fixed Chinese colloquial style and to avoid industry jargon, but they do not give the user any option to choose another language or locale. This is a natural-language policy concern because the skill imposes a language/style preference without explicit user opt-in.
