Fence Quote Calculator

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward fence material takeoff helper with no code execution, data access, persistence, or hidden behavior.

Before installing, understand that this skill may activate for general fence-estimating conversations involving Reese; verify the project layout and local material specs before relying on the quantities.

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 phrases "Any mention of calculating fence materials" and "Pricing or estimating a fence project" are open-ended and do not clearly bound when the skill should or should not activate. Without narrower constraints or exclusion examples, the skill may be invoked during general conversation about estimates rather than explicit requests to run this calculator.
