Security checks for vulnerabilities and agentic risk

Overview

This is a text-rewriting skill whose file access is aligned with editing documents and shows no hidden execution, persistence, or data exfiltration behavior.

Use this skill for intentional rewriting tasks and review diffs before accepting changes, especially for legal, policy, academic, quoted, or compliance-sensitive text where exact wording 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
Category
Not specified by scanner
Confidence
89% confidence
Finding

The phrase "Or invoke directly when editing documents" does not define specific trigger words, scope, or exclusion conditions for when the skill should activate. In a markdown skill description, this kind of broad activation guidance can cause unintended invocation during ordinary document editing.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The description is broadly scoped to 'editing or reviewing text to make it sound more natural and human-written,' which can cause the skill to activate in many contexts without clear user intent boundaries. In an automated agent environment, that increases the chance of unintended rewriting of sensitive, compliance-relevant, or user-authored text where preserving exact wording matters.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill has Write and Edit permissions and is designed to rewrite text, but it does not clearly warn that it may directly modify files rather than just propose edits. That can lead to silent or unexpected changes to repository content, including loss of author intent, corruption of quoted material, or accidental edits to high-integrity documents.
