Structs UI

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only Structs UI/client skill whose sensitive topics are disclosed and tied to its stated game-client purpose.

Install this if you want Structs-specific UI or client-building guidance. Be aware it includes references for wallet signing and transaction queues, so review any generated transaction code carefully and keep user confirmation around real signing actions.

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 skill description is broad enough to match generic UI-building or client-development requests beyond the Structs ecosystem, which can cause inappropriate routing and tool selection. In an agent system, overbroad invocation increases the chance the model applies domain-specific instructions, external references, or transaction-signing guidance in unrelated contexts, creating confusion and potentially unsafe assistance.
