Security checks for vulnerabilities and agentic risk

Overview

This is a document-editing skill whose main risk is misuse to disguise AI-written text, but the artifact does not show hidden execution, exfiltration, or persistence.

Use this only for legitimate editing and readability improvements. Do not use it to evade school, workplace, publication, legal, or platform disclosure rules about AI assistance, and review changes before allowing it to write back to files.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category

Confidence
93% confidence
Finding

The phrase "Or invoke directly when editing documents" does not define specific trigger phrases, contexts, or exclusion conditions. In a markdown skill description, this kind of broad activation guidance can overlap with common editing activity and makes it unclear when the skill should or should not run.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill explicitly aims to remove signs of AI-generated writing and make text appear human-written, which can facilitate deceptive disclosure practices in academic, journalistic, compliance, or customer-facing contexts. While the file does not contain code execution or data exfiltration behavior, the core functionality encourages concealment of AI assistance without requiring user justification, transparency, or policy checks.
