Fitness Plan

Security checks for vulnerabilities and agentic risk

Overview

This fitness skill appears benign; it provides local workout reference guidance, though some documented calculator and planning commands do not match the bundled script.

Review the fitness advice as general guidance, not medical care. Expect the bundled script to provide static reference sections; the documented calculate and plan examples may not work unless the publisher updates the script.

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 includes both English and Chinese text by default, which imposes multilingual output expectations without explicitly asking the user for a preferred language. The policy requires offering a language or locale choice unless the constraint is clearly documented and justified.
