Security audit

Language

Security checks for vulnerabilities and agentic risk

Overview

This is a markdown-only language-learning skill with coherent personalization features and no executable code, hidden commands, or privileged behavior.

Safe to install for language-learning help. Share only the personal context needed for better examples, and avoid sensitive personal details unless you intentionally want them used in practice material.

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

Finding

The skill metadata describes broad capabilities but does not define when the skill should be invoked or what requests fall outside its scope. In an agent environment, ambiguous scope can cause over-invocation, unintended handling of unrelated user data, or use of the skill in contexts where its guidance is unreliable, increasing privacy and safety risk.

Missing User Warnings

Confidence

Finding

The skill explicitly encourages use of personal details such as name, city, profession, and ongoing progress tracking, but provides no notice about data minimization, retention, or user consent. In practice, this can lead users or the hosting agent to disclose and store unnecessary personal information, creating avoidable privacy exposure if logs are retained, shared, or reused.
