Qrqc Quick Response

Security checks for vulnerabilities and agentic risk

Overview

This skill is a plain Markdown workflow for creating QRQC manufacturing response boards, with only low-risk local report output noted.

Before installing, treat it as a report-template skill: review generated board contents for accuracy, and ask the agent to write outputs to a dedicated folder or unique filename if same-day report collisions matter.

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

Missing User Warnings

Low
Confidence
86% confidence
Finding
The skill explicitly instructs the agent to generate local output files (.txt and .md) via a script, but it does not warn the user that files may be created or overwritten on disk. In an automated agent environment, this can lead to unintended filesystem side effects, especially if filenames collide with existing files or the working directory is shared.
