Security audit

Security checks for vulnerabilities and agentic risk

Overview

This is a plain text-editing skill for making writing sound less AI-generated, with no hidden execution, network, credential, or persistence behavior found.

Install this only if you want the agent to rewrite prose to sound more natural and less AI-like. Review edits before accepting them, especially for factual, legal, academic, or brand-sensitive writing, because the skill may make tone stronger or more personal.

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

Finding

The phrase "Or invoke directly when editing documents" does not define specific trigger phrases, scope limits, or exclusion conditions. Because this README is a markdown file, vague activation language applies here and could lead to accidental or overly broad skill invocation.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The skill description is broad enough to match ordinary editing or reviewing requests, which can cause the agent to invoke this skill in contexts where the user did not specifically ask to humanize text. That increases the chance of unintended rewriting of user content, including changing tone, adding first-person phrasing, or altering meaning under the instruction to 'add soul' and 'have opinions.'
