Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only skill for designing and reviewing Agent Skills, with no hidden code, network behavior, persistence, or credential handling found.

Install this if you want help designing or improving reusable Agent Skills. It can guide an agent to create or edit skill package files during user-directed work, so review generated skills before publishing, but this package itself does not contain executable code or hidden privileged behavior.

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

This README describes when to use the skill as 'creating or improving reusable Agent Skills, especially skills intended for public distribution,' but it does not provide specific trigger phrases, exclusions, or negative examples. For a markdown skill description, that broad invocation guidance can overlap with many general engineering tasks and make activation boundaries unclear.
