SWFL Data Gulf

Security checks for vulnerabilities and agentic risk

Overview

This skill is a public-data lookup guide for Southwest Florida market information and does not show hidden execution, credential use, persistence, or destructive behavior.

Install this only if you want the agent to fetch public SWFL Data Gulf market data from swfldatagulf.com. Do not provide credentials or ask it to make purchases; the skill itself says reads are free and no authentication is needed.

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
