Security checks for vulnerabilities and agentic risk

Overview

This skill only documents how to query public KNHB Dutch field hockey schedule and results data, with no hidden execution, persistence, or credential behavior.

Install only if you want KNHB/Dutch field hockey lookup help. The skill will guide an agent to make public API requests to hockeyweerelt.nl and process responses locally with common command-line tools.

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 description limits the skill to Dutch field hockey information in the Netherlands and frames usage around that locale only. While this may be inherent to the data source, the file does not explicitly document that this is a region-specific skill or offer any user opt-in/choice around locale scope.
