Stretch

Security checks for vulnerabilities and agentic risk

Overview

This is a static stretching reference skill with no data access or persistence, though its advanced PNF advice should be used cautiously.

Installers should treat this as general fitness reference material, not medical care. Be especially cautious with PNF or partner stretches: do not force range of motion, stop with pain, numbness, tingling, or joint symptoms, and consult a qualified coach, physical therapist, or clinician if injured, hypermobile, rehabilitating, or unsure.

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 PNF section gives advanced contract-relax instructions, including partner-assisted stretching and use around injured or sensitive muscles, but does not clearly direct users to seek qualified supervision or medical advice before attempting higher-risk techniques. Because this skill is a practical exercise reference, users may follow it directly and overreach, increasing the chance of strain, joint irritation, or worsening an existing condition.
