Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward packing-list generator with disclosed, purpose-aligned behavior and no evidence of hidden access, network use, persistence, or credential handling.

Before installing, treat this as a local Python checklist generator. Use the --output option only with a path where you are comfortable creating or overwriting a JSON packing list.

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: 88% confidence
Finding: The skill documentation exposes file-write capability via the --output checklist.json behavior, but the manifest declares no explicit tool scope or allowed tools. That mismatch can lead to over-privileged execution or unclear review boundaries, making it easier for an agent runtime to permit filesystem writes without informed consent or policy gating.
Content: No source excerpt is available for this finding.
