Fitness Trainer

Security checks for vulnerabilities and agentic risk

Overview

This is a simple fitness guidance skill with no code execution or hidden system access, though users should treat its exercise and nutrition advice as general guidance rather than medical advice.

Install only if you want general workout and nutrition education. Do not rely on it for injury treatment, medical nutrition therapy, pregnancy-specific guidance, minors, eating-disorder concerns, supplements or drugs, or chronic conditions without qualified professional advice.

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

Finding

The skill trigger is broadly phrased to activate on general fitness, exercise, nutrition, or training requests, which increases the chance it will be invoked in situations that require personalized medical, injury, or eating-disorder-sensitive guidance. In an agent system, over-broad routing can expose users to advice outside the skill's safe competence boundary without appropriate triage or disclaimers.

Missing User Warnings

Confidence

Finding

The skill gives workout programming and nutrition guidance but includes no warning that it is not medical advice and no guardrails for injuries, chronic conditions, pregnancy, minors, or disordered-eating risk. In this context, omission of safety boundaries can lead users to follow inappropriate exercise or diet recommendations that worsen injuries or health conditions.
