Motor FOC Control

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent Chinese-language FOC motor-control guide with a local PI tuning helper script, but users should apply its tuning advice cautiously on real hardware.

Install only if you are comfortable with Chinese-language motor-control material. Treat the PI and flux-weakening outputs as theoretical starting points, not ready-to-run production settings; validate on current-limited, speed-limited, temperature-monitored hardware with emergency stop and rollback procedures.

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 (6)

Tp4

High

Category: MCP Tool Poisoning
Confidence: 94% confidence
Finding: The declared description presents a comprehensive FOC learning guide with multiple advanced motor-control topics and accompanying materials. The supplied code, however, only implements a PI tuning tool for current and speed loops, plus optional discretization correction and Bode plotting. This is related to one small part of the description ('PI tuning script') but does not substantiate the broader declared purpose. Therefore the description materially overstates the code's scope and capabilities.
Content: No source excerpt is available for this finding.

Ae4

Medium

Category: analysis-evasion
Confidence: 80% confidence
Finding: Suspicious Unicode normalization or mixed-script content
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 96% confidence
Finding: The manifest description and main content are written entirely in Chinese, and the file does not indicate that users may choose another language or that the skill is intentionally restricted to a Chinese-speaking region or audience. Under the policy, a language or locale constraint without user opt-in or clear justification is a natural-language policy violation.
Content: No source excerpt is available for this finding.

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 93% confidence
Finding: The skill gives live motor-control tuning, flux-weakening, and PI adjustment guidance that could be applied directly to physical hardware without prominent safety constraints. In this context, unsafe tuning can cause overcurrent, overspeed, inverter stress, demagnetization, or mechanical damage, especially during flux-weakening and closed-loop parameter changes.
