书桌书柜定制避坑指南

Security checks for vulnerabilities and agentic risk

Overview

This skill provides desk and bookcase design advice without requesting sensitive access or running software.

Use this as a design reference. Some source text contains extraction errors, and the expert persona is not a verified qualification. Have an installer confirm mounting and load-bearing details before construction.

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

Context Window Stuffing

Medium

Category: Memory Poisoning
Confidence: 80% confidence
Finding: Skill attempts to fill the context window with filler content, displacing legitimate instructions and safety constraints. This can degrade agent performance or bypass safety boundaries.
