Verified Humanizer New

Security checks for vulnerabilities and agentic risk

Overview

This skill is a privacy-focused writing rewrite aid with optional metrics-only verification and no evidence of hidden data access or unsafe execution.

Reasonable to install for local rewriting and style cleanup. Treat optional verification carefully: only send aggregate metrics, not original text, rewritten text, secrets, credentials, or private content. Be aware that the skill may activate broadly on general polishing requests.

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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Finding

The phrase 'Use this skill when text sounds generic, repetitive, over-explained, overly polished, or obviously AI-shaped' relies on subjective descriptors without explicit trigger phrases, scope boundaries, or exclusion examples. In a markdown skill description, this can cause ambiguous activation because many ordinary writing tasks could match these broad conditions.

Finding

Lines L14-L15 state that no private text was sent to any verifier and that verification, if used, covers metrics only. In this file, however, that guarantee is presented as a checklist assertion rather than a technical control, so the documentation conveys a stronger privacy claim than the file itself substantiates.
