Motor Parameter Calculator

Security checks for vulnerabilities and agentic risk

Overview

This is a narrow motor-parameter calculator skill with no evidence of hidden access, persistence, network use, or credential handling.

Install only if a Chinese-language motor design calculator fits your workflow. Treat the numerical outputs as engineering estimates and be aware that the JavaScript helper appears to have some functional issues, so the Python script is the clearer documented path.

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 (10)

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: 95% confidence
Finding: The manifest description, headings, usage guidance, and sample dialogue are entirely in Chinese, which implies a fixed language experience. There is no indication that users may choose another language or that the skill is intentionally limited to a Chinese-only regulatory or regional context.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 94% confidence
Finding: The manifest explicitly sets the skill language to "中文", which indicates a fixed language requirement. Under the policy, language constraints should either offer user choice or be clearly justified as region-specific; this file provides neither.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The header comments, usage guidance, and user-facing descriptions are presented only in Chinese. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale constraint is explicitly justified, which is not stated here.

Intent-Code Divergence

Low

Category: Not specified by scanner
Confidence: 94% confidence
Finding: The header comment says users can run node calculator.js --mode compare_slots, implying a --mode-based interface. In the actual code, the only supported comparison trigger is --compare_slots in main(), and parseArgs() ignores standalone flags like --mode, so the documented invocation will not perform the described behavior.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 94% confidence
Finding: SQP-3 applies to all file types and covers language or locale policy violations. This file presents its description, usage context, CLI help text context, and interactive UX in Chinese only, with no opt-in, alternate language path, or justification that the tool is intended solely for a Chinese-speaking or region-specific audience.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 96% confidence
Finding: The interactive mode communicates exclusively in Chinese and does not provide any user-selectable language setting. Under SQP-3, forcing a specific language without user opt-in is a natural-language policy concern even when the file is otherwise non-sensitive.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 91% confidence
Finding: The argparse description and help strings are visible user-facing text and are all written in Chinese. Because the file does not offer locale choice or document a justified language restriction, this matches the SQP-3 language-policy criterion.
Content: No source excerpt is available for this finding.
