Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple document-generation helper with no hidden execution, credential use, persistence, or network behavior.

Install this if you want a helper for drafting structured Markdown documents. Review generated content before using it, and be aware it may save a .md file in the current directory when your request implies you want a file created.

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

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill description contains broad trigger phrases such as 'help me write a doc' and 'create a report,' which can match many ordinary user requests and cause the skill to activate outside a narrowly scoped context. Overbroad activation increases the chance of unintended routing or auto-application, which can override more appropriate skills and lead to unreviewed file-writing behavior when the skill later instructs saving a .md file to disk.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

This JSON eval file contains prompt strings written in Chinese for all examples, which imposes a specific language context without any indication that the skill offers language choice or is intentionally region-specific. Under the stated policy, forcing a language or locale without opt-in is a natural-language policy violation.
