AI Text Humanizer — Remove AI Writing Patterns

Security checks for vulnerabilities and agentic risk

Overview

This is a document-editing skill that rewrites AI-sounding text, with no evidence of hidden execution, network access, credential handling, or persistence.

Install only if you want an agent to rewrite user-provided or local document text to sound less AI-generated. Review proposed edits before saving or publishing, especially where tone, attribution, or factual precision matters.

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

Not specified by scanner
Confidence
91% confidence
Finding

The phrase "Or invoke directly when editing documents" does not specify exact trigger phrases, scope, or exclusion conditions for when the skill should activate. Because ordinary document editing is a very common context, this ambiguity could cause unintended invocations.

Vague Triggers

Confidence
88% confidence
Finding

The description says to use the skill when "editing or reviewing text," which is a very broad context that overlaps with many ordinary writing tasks. It does not clearly distinguish when the skill should activate versus when a general editing skill should be used, nor does it provide exclusions or negative examples.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
80% confidence
Finding

The manifest grants Write and Edit capabilities, and the instructions direct the skill to rewrite problematic sections and present a humanized version. However, the markdown does not explicitly warn users that the skill may substantially rewrite their text or recommend review before applying changes, which is a user-impacting behavior for markdown-scoped warning checks.
