Security checks for vulnerabilities and agentic risk

Overview

This skill is a text editor, but its stated goal is to hide signs that writing was AI-generated without adding disclosure or misuse limits.

Install only if you want an editor that rewrites text for naturalness and you will use it on drafts you are allowed to edit. Do not use it to conceal AI authorship where disclosure is required, for academic dishonesty, impersonation, spam, or misleading provenance claims.

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

Natural-Language Policy Violations

Finding

The skill explicitly aims to remove signs of AI-generated writing and make text sound human-written, but it includes no consent, disclosure, or use-policy constraints. That creates a direct pathway for deception, including plagiarism laundering, impersonation, spam optimization, and bypassing rules that rely on truthful disclosure of AI assistance.

Vague Triggers

Finding

The skill description is broad enough to activate on ordinary editing or review tasks, which increases the chance it will be invoked outside a narrow, user-intended context. Because the skill’s purpose is to rewrite text to appear more human-written, overbroad triggering can silently steer benign writing assistance into deceptive obfuscation workflows.
