Cn Cost Control

Security checks for vulnerabilities and agentic risk

Overview

This is a static Chinese construction cost-control reference skill with no code execution, persistence, credential handling, or hidden data flows.

Install this if you want Chinese construction cost-control guidance based on Chinese standards; users needing another jurisdiction or language should verify applicability, but no security-sensitive behavior was found.

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 (3)

Ae4

Medium

Category: analysis-evasion
Confidence: 80% confidence
Finding: Suspicious Unicode normalization or mixed-script content

Natural-Language Policy Violations

Medium

Confidence: 88% confidence
Finding: The organizational policy category forbids forcing a specific language or locale without user opt-in. The top-level description is presented only in Chinese and does not state that the skill is China-specific by choice of the user or offer an alternative language option.

Natural-Language Policy Violations

Medium

Confidence: 88% confidence
Finding: The manifest presents the skill name and description entirely in Chinese, which indicates a fixed language/locale for the skill experience. Under the policy, forcing a specific language without user opt-in or a clearly documented locale-specific justification is a natural-language policy concern.
