Security audit

Memory Taxonomist

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple memory-classification guide with disclosed storage recommendations and no executable code, though users should be mindful about what they choose to persist.

Install only if you want help structuring notes for possible memory storage. Before accepting any recommended storage action, avoid saving secrets or sensitive personal data unless you explicitly intend to, and review whether items should be stored, updated, held, or kept ephemeral.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The activation triggers are broad and subjective, so an agent could invoke this skill in many contexts involving notes, memory, or retrieval without clear gating. Because the skill explicitly touches memory handling and user context, over-invocation can cause unnecessary persistence, misclassification of sensitive information, or use outside the user's intent.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill references storing user context safely for future retrieval but provides no privacy warning, consent requirement, retention guidance, or limits on what may be stored. In a memory-oriented skill, this omission is meaningful because users or downstream agents may infer that personal, sensitive, or provisional information can be persisted by default.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
87% confidence
Finding

The default prompt is broad enough to match many ordinary 'classify this information' requests, and with implicit invocation enabled this can cause the skill to activate without clear user intent. That increases the chance of unintended memory processing or storage behavior, especially when users are asking for generic summarization or organization rather than durable memory creation.
