Symptom Check

Security checks for vulnerabilities and agentic risk

Overview

This is a simple symptom-check guidance skill with no code or hidden system access, though its medical scope should be used cautiously.

Install only if you want general, non-diagnostic symptom guidance. For severe, sudden, or emergency symptoms, users should contact emergency services or a licensed clinician rather than relying on this skill.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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

Finding

The manifest description is broad enough to trigger on many ordinary health-related queries, which can cause the skill to activate outside a narrowly defined scope. In a medical-adjacent context, overbroad routing is risky because users may receive generalized symptom guidance in situations that require urgent triage, professional diagnosis, or a more specialized safety workflow.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The usage criteria are ambiguous and lack clear boundaries for when the skill must not be used, creating a real risk of unsafe activation on serious medical scenarios. Because the skill concerns health symptoms, unclear activation conditions can lead to delayed escalation, inappropriate reassurance, or incomplete handling of red-flag symptoms.
