Football

Security checks for vulnerabilities and agentic risk

Overview

This football analysis skill is coherent and limits itself to optional local notes and task-specific football guidance.

Before installing, decide whether you want this skill to save a small local football notebook in ~/football/ and choose a narrow activation setting if you only want it to help when explicitly asked. Do not store private videos, medical details, or sensitive team information unless you are comfortable keeping that locally.

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

Vague Triggers

Medium
Confidence
91% confidence
Finding
The activation scope is broad enough to trigger on generic football or soccer discussions, which can cause the skill to engage and potentially influence conversations beyond the user's intended context. While this is not overtly malicious, overbroad activation can lead to unnecessary memory use, unintended persistence-related prompts, and confusion about when the skill is active.

Vague Triggers

Medium
Confidence
94% confidence
Finding
The activation rule is overly broad because it triggers whenever the user mentions common football-related terms, even if they are incidental or not a request for specialized help. This can cause the skill to activate unexpectedly, steer conversations away from user intent, and increase unnecessary collection or retention of user context in early exchanges.
