Spec's Liquor Prices API - Every Texas Store, Search, Store Locator

Security checks for vulnerabilities and agentic risk

Overview

This skill performs disclosed product and store lookups through Scavio, with no evidence of hidden data collection or harmful actions.

Scavio receives your searches and store selections, and calls consume credits. Keep the API key out of shared files. Direct HTTP calls avoid installing additional software; if using MCP, consider enabling only 'specs'. Optional dependency code and live service behavior were not audited.

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
