Resume Risk Screen

Security checks for vulnerabilities and agentic risk

Overview

This is a text-only resume screening skill whose instructions fit its stated HR review purpose and do not add hidden execution, persistence, or data exfiltration behavior.

Install this if you want a Chinese-language resume risk-screening workflow. Because it processes resumes and contact details, users should provide only candidate data they are authorized to review and should treat the generated risk labels as screening assistance, not a final hiring decision.

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

Finding

This pattern attempts to override system instructions or ignore safety constraints. Without LLM analysis, manual review is recommended.

Natural-Language Policy Violations

Finding

The README is written entirely in Chinese and instructs the agent to produce the screening report in that context, but it does not state that the skill is China-specific or give users an option to choose another language. This creates a natural-language locale policy concern because the skill appears to impose a specific language without explicit user opt-in.

Natural-Language Policy Violations

Confidence
94% confidence
Finding

The title and the surrounding instructions are written as a Chinese-only operating mode, and the output templates and examples are likewise presented in Chinese. There is no indication that the user may choose another language or that the locale restriction is optional, which matches the language/locale policy violation criteria.
