Artifact Deck

Security checks for vulnerabilities and agentic risk

Overview

This skill is a local deck-building helper that reads user-chosen notes and images and writes user-chosen deck, JSON, and summary files.

Install only if you are comfortable with a skill that reads the note and image paths you provide and writes or overwrites the output paths you choose. Use a dedicated project/output folder to avoid accidental overwrites.

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

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
93% confidence
Finding

The skill clearly instructs the agent to read local files (markdown inputs, screenshots, manifests) and write multiple outputs (.json, .pptx, .md), but it does not declare any explicit tool scope such as permissions or allowed-tools. That mismatch weakens least-privilege controls and can let the runtime grant broader filesystem access than users or platforms expect, increasing the chance of unintended file access or overwrite.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
83% confidence
Finding

This code writes data to disk by creating parent directories and overwriting the target file, but it includes no confirmation prompt, logging, print statement, or explanatory comment/docstring describing that behavior. For code files, file writes are safety-relevant when there is no visible disclosure at the point of implementation.
