Weekly Symptom Appointment Log

Security checks for vulnerabilities and agentic risk

Overview

This is a prompt-only health appointment preparation skill that organizes user-provided symptom notes and does not request code execution, network access, credentials, or persistence.

Install only if you are comfortable entering health details into your AI assistant for appointment preparation. Review outputs for accuracy before sharing with a clinician, and use emergency or crisis services for severe, sudden, dangerous, or rapidly worsening symptoms.

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
Vulnerability Patterns
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
Findings (4)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

Line L205 states the skill must produce "English-only prompt-flow content," which is a language-policy restriction expressed in natural language. The file does not offer the user a language choice or explain a justified region-specific need for English-only output.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

The acceptance criteria state "Skill is English-only," which is a natural-language locale restriction. Under the policy, forcing a specific language without user opt-in can be a violation unless the constraint is justified as region-specific or the user is offered a choice.

Scope Creep

Low
Category
Excessive Agency
Confidence
70% confidence
Finding

Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.

md
Before routine logging, ask whether any urgent red flags are present. Keep this general and safety-focused.

Advise urgent care or emergency services now if the user reports severe, sudden, or potentially life-threatening symptoms, including but not limited to:

- Chest pain, pressure, trouble breathing, fainting, or signs of stroke
- Severe allergic reaction, swelling of face or throat, or trouble swallowing

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
89% confidence
Finding

The manifest sets the skill language to "en" with no indication that users may opt into another language or that the skill is intentionally limited to English for a documented reason. Under the policy, forcing a specific language without user choice can be a natural-language policy violation.
