Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed writing editor for making text sound less AI-generated, with no code execution, network use, credential access, or persistence found.

Install only if you want an agent to rewrite text for a more natural style. Use it on documents you are authorized to edit, and do not use it to misrepresent authorship where disclosure rules, academic policies, workplace policies, or publication standards require transparency.

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

Finding

The phrase "Or invoke directly when editing documents" does not specify what exact trigger phrases, contexts, or exclusions activate the skill. In a markdown skill description, this ambiguity can cause unintended invocation during ordinary document-editing workflows.

Natural-Language Policy Violations

Confidence
97% confidence
Finding

The skill explicitly instructs the agent to make text sound more human-written and to 'remove signs of AI-generated writing,' which can enable deceptive authorship masking if used without clear user consent or disclosure. While framed as an editing aid, the functionality materially helps users evade AI-detection heuristics and impersonate human authorship, making the static finding valid in context.
