Concept Decoder

Security checks for vulnerabilities and agentic risk

Overview

This is a markdown-only teaching skill with no code execution, external access, or hidden persistence.

This skill appears safe to install for structured concept explanations. Expect long educational responses and an initial prerequisite check before the full explanation; no special local or account permissions were found.

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

Finding

The subtitle presents the skill as bilingually fixed, and the document consistently duplicates content in English and Chinese throughout the README rather than indicating that language output is optional or user-selectable. Under the policy, forcing a specific language or locale without opt-in can be a natural-language policy violation.
