Security checks for vulnerabilities and agentic risk

Overview

This is a text-editing skill that rewrites AI-sounding prose, with no hidden code execution, network use, persistence, or credential handling found.

Before installing, treat this as an editor that may actively rewrite documents and style choices. Review diffs for factual accuracy, tone, and typography preferences, especially if preserving exact wording or regional style 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

  • 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
Category
Not specified by scanner
Confidence
90% confidence
Finding

The phrase "Or invoke directly when editing documents" does not define specific trigger phrases, scope limits, or exclusion conditions. Because it describes activation in a very broad context, it could cause unintended invocation during ordinary document editing activity.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The manifest says to use the skill when 'editing or reviewing text,' which is a very common and expansive context rather than a narrowly scoped trigger. The file does not provide explicit trigger phrases, boundaries, or negative examples to clarify when the skill should or should not activate, increasing the chance of unintended invocation.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
85% confidence
Finding

The skill instructs the agent to replace curly quotation marks with straight quotes as a general rule, which imposes a specific typography/locale convention rather than preserving user or regional style preferences. The document does not offer an opt-in choice or limit this behavior to a justified house style.
