Security checks for vulnerabilities and agentic risk

Overview

This skill is a focused PLC code review guide that reads user-selected PLC files and produces structured analysis without hidden execution or persistence.

Install this if you want a Chinese-oriented PLC ST code analysis checklist and report format. Before relying on its output for production safety, have a qualified controls or safety engineer validate any safety-interlock findings and proposed code changes.

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

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 94% confidence
Finding: The manifest description and top-level documentation are written entirely in Chinese and present the skill as a Chinese-language toolkit, with no indication that users may request another language. This creates a natural-language locale constraint without opt-in or justification, which matches the policy-violation category for language or locale restrictions.
Content: No source excerpt is available for this finding.
