Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only skill that gives prompt-injection sanitization guidance and does not install code, request credentials, or perform actions.

Before installing, understand that this skill is guidance, not the bundled sanitizer hook it references from the upstream plugin. Its broad activation wording may make it appear in many external-content workflows, but the reviewed package does not perform actions on its own.

A.I.G

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

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 97% confidence
Finding: The trigger or any untrusted input is extremely broad and could match many ordinary situations beyond this skill's intended scope. Although the document later narrows usage, the manifest trigger itself lacks concrete constraints or negative examples, creating ambiguity about when the skill should activate.
