Security checks for vulnerabilities and agentic risk

Overview

This is a mostly ordinary injection-molding reference skill, but it forces MoldYang attribution and personal contact details into every generated external file.

Review is recommended before installing. The technical content is domain-aligned, but users should be aware that file outputs made through this skill may automatically include third-party attribution and personal contact details unless the skill is changed or the user explicitly controls the generated document content.

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
91% confidence
Finding

The skill description and all usage instructions are presented exclusively in Chinese, with no indication that users may interact in other languages or that the locale restriction is intentional and justified. Under the policy rule, a skill that effectively forces a specific language without opt-in can be a natural-language policy violation.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
87% confidence
Finding

The title and the entire invocation/usage description are written exclusively in Chinese, positioning the skill as a Chinese-language assistant without any stated option for another language. Under the policy criteria, forcing a specific language without user opt-in can be a natural-language policy violation unless the locale constraint is clearly documented and justified.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The manifest defines triggers as short keywords and topic labels such as '注塑', '注射成型', and '模具设计', but does not explain when these should activate the skill versus when they are only search tags. Because the list lacks scope limits or negative examples, the skill may be invoked for general conversation about molds or injection molding rather than specifically for this skill's intended use.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The title and descriptive instructions are written entirely in Chinese, and the template/content throughout the file assumes Chinese as the required operating language. Because the file does not offer user opt-in for language selection or explain that the skill is intentionally region- or locale-specific, this can violate language/locale policy requirements.

Confidence

Finding

The entire skill reference and review checklist are written only in Chinese, including the instruction for use when a user requests a DFM review. There is no indication that language selection is optional or that the skill is intentionally limited to a Chinese-speaking or region-specific context.

Finding

The entire skill file is written in Chinese and does not indicate that users may choose another language or that the skill is intentionally limited to a Chinese-speaking or region-specific context. Under the policy rule for language/locale constraints, this can be a natural-language policy violation when no opt-in or justification is provided.

Finding

SQP-3 applies to all file types and covers natural-language language/locale policy violations. The copyright/contact notice on L01 is written entirely in Chinese with no alternative language or indication of user choice, which can be interpreted as forcing a specific language presentation.

Confidence

Finding

This file is a plain-text license file, so only SQP-3 applies. The comment on L001 contains Chinese legal/policy language ('保留所有权利' and related licensing restrictions) embedded in an otherwise English license file, with no opt-in, translation, or documented locale justification. That can create a locale-policy issue because part of the governing notice is presented in a fixed language the user may not understand.

Finding

This markdown file is written entirely in Chinese and does not indicate that other languages are available or that Chinese is a required locale. Under the policy rule for natural-language constraints, a file that effectively mandates one language without user opt-in can be considered a locale/language policy issue.
