Security checks for vulnerabilities and agentic risk
Overview
This is a coherent patent-assistance skill with one unsafe setup example users should avoid copying directly.
Install only if you want Chinese-language patent workflow help. Do not copy the Graphviz/Python PATH example as-is; use trusted local installs, verify the resolved Graphviz executable, and prefer a virtual environment. Treat the patent outputs as drafting support rather than legal advice.
Vulnerability Patterns
- Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
- 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

- Finding
Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.

Vague Triggers
Medium
- Category
- Not specified by scanner
- Confidence
- 90% confidence
- Finding
The trigger description activates on a wide set of common patent-related phrases, so the skill may be invoked in loosely related contexts without strong intent matching. Over-broad activation can cause unintended routing, inappropriate disclosure of specialized guidance, or interference with other safer/more relevant skills, especially in multi-skill agent environments.

Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 90% confidence
- Finding
The entire template is written in Chinese and provides no indication that other languages are supported or that Chinese is required for a specific regional compliance reason. This can violate language/locale policy when users are not given an explicit language choice or opt-in.

Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 86% confidence
- Finding
The entire skill content is written in Chinese and does not indicate that language selection is optional or limited to a China-specific/regional use case. Under the policy, forcing a specific language without user opt-in can be a natural-language policy violation.

Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 91% confidence
- Finding
The document is written entirely in Chinese and immediately prescribes Chinese-specific tooling choices such as Chinese font rendering, but it does not state that the skill is region-specific or provide any language/locale opt-in. Under the policy, forcing a specific language without user choice is a natural-language policy violation unless the locale constraint is explicitly justified.

Natural-Language Policy Violations
Low
- Category
- Not specified by scanner
- Confidence
- 80% confidence
- Finding
The natural-language instructions and examples are entirely in Chinese, and the file does not state that users may interact in other languages or opt into Chinese output. Under the policy, forcing a specific language without user choice can be a locale-policy issue unless clearly justified as region-specific.

- Confidence
- 88% confidence
- Finding
This markdown file presents all instructions and output requirements exclusively in Chinese, and does not indicate that the user can choose another language or that the skill is intended only for a Chinese-speaking or region-specific context. Under the policy, forcing a specific language without opt-in is a natural-language policy concern.
