multisim-debug-circuit

Security checks for vulnerabilities and agentic risk

Overview

This skill gives bounded instructions for debugging Multisim circuit simulations and requires reversible changes plus user approval before persistence.

Before installing, confirm you use the Multisim MCP workflow and are comfortable allowing the agent to inspect circuit-related logs, netlists, commands, reports, and experiment directories. Review any proposed DesignPatch before approving persistence to the original project.

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 (1)

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 84% confidence
Finding: The file presents the primary instructions in Chinese and then adds a brief English summary, but it does not explicitly state that language can be chosen based on user preference. This can create a language/locale policy issue if the skill effectively defaults to a specific language without opt-in.
Content: No source excerpt is available for this finding.
