Physical Therapy Homework Tracker

Security checks for vulnerabilities and agentic risk

Overview

This is a prompt-only physical therapy homework organizer with clear medical safety boundaries and no code, network access, credential use, or persistence.

Installers should understand this skill is for organizing an existing clinician-prescribed PT plan only. Do not use it for diagnosis, new exercise recommendations, progression decisions, or deciding whether symptoms are safe; bring unclear instructions, worsening symptoms, or red flags to a clinician or urgent care.

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

Anti-Refusal Statement

Anti-Refusal
Confidence
80% confidence
Finding

Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.

- Organize prescribed exercises, sets, reps, frequency, equipment, and restrictions.
- Build a daily or weekly home-program checklist.
- Track adherence without judging or redesigning the program.
- Record pain, discomfort, fatigue, range-of-motion notes, confidence, or skipped-session reasons.
- Prepare a concise next-appointment update.
- Draft questions about unclear movements, symptom changes, barriers, or modifications to ask the clinician.

Natural-Language Policy Violations

Confidence
97% confidence
Finding

The acceptance criteria explicitly require public-facing documentation to be English only. This is a natural-language locale restriction and there is no indication that users are offered a language choice or that the constraint is justified as region-specific.

Natural-Language Policy Violations

Category
Not specified by scanner
Confidence
93% confidence
Finding

The manifest sets the skill language to "en", which indicates an English-only constraint. Under the policy, forcing a specific language without offering user choice or documenting a justified regional/compliance reason is a natural-language policy violation.
