PickleBase Biomechanics & 3D Tactical Coach

Security checks for vulnerabilities and agentic risk

Overview

The skill makes clearly disclosed requests for pickleball coaching information without requesting private files, credentials, or lasting system changes.

This skill uses PickleBase's external service. The supplied examples require no credentials or private files. Keep any additional query content limited to information you are comfortable sharing; publisher identity and server-side retention were not independently verified.

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
