Migraine Trigger Pattern Log

Security checks for vulnerabilities and agentic risk

Overview

This is a prompt-only migraine logging aid with no code, network access, credentials, or persistence, but users should treat it as tracking support rather than medical advice.

Before installing, consider that the skill handles sensitive health details. Share only what you are comfortable sharing, do not use it to self-diagnose or change medication, and seek urgent local medical care for severe, sudden, new, worsening, neurological, pregnancy-related, injury-related, vision-related, fever-related, or otherwise alarming 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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Finding

Code or instructions that leak agent conversation context to external services, potentially exposing sensitive user interactions.

1. **Check for urgent red flags first.** If the user describes sudden severe headache, neurological symptoms, fever, head injury, pregnancy-related concerns, new or worsening pattern, or other alarming signs, advise urgent local medical care before routine logging.
2. **Define the tracking goal.** Clarify whether the user wants a daily template, an episode-by-episode log, a weekly review, or an appointment summary.
3. **Record each episode.** Capture date, start time, end time, severity, pain location, symptom details, disruption level, and what the user was doing when it began.
4. **Capture context factors.** Add fields for sleep, meals, hydration, caffeine, alcohol, stress, screens, weather, cycle, exercise, travel, illness, and unusual routine changes.
5. **Track interventions and response.** Record medication or other steps used, dose only if the user provides it, timing, relief level, side effects, and whether symptoms returned.
6. **Review repeated patterns cautiously.** Identify repeated associations and unknowns without claiming causation or telling the user what caused the migraine.
7. **Create an appointment summary.** Condense frequency, duration, severity range, common symptoms, possible patterns, treatments tried, response, red flags, and top questions.

Natural-Language Policy Violations

Confidence
96% confidence
Finding

The acceptance criteria explicitly require public-facing documentation to be English only. This is a natural-language locale restriction, and the file does not indicate user choice, opt-in, or a region-specific justification that would exempt it under the policy.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The clean scan evidence states that SKILL.md, skill.json, and ACCEPTANCE.md must be English only. Requiring a single language across artifacts is a locale policy constraint, and no user opt-in or justified regional limitation is provided in this file.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
91% confidence
Finding

The manifest sets the skill language to "en", which indicates an English-only constraint. In this health-related skill, the file does not document any user opt-in or region-specific justification for restricting the skill to English.
