Vvvv Dotnet

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only skill for vvvv gamma .NET integration, and the network/package guidance it contains is disclosed and aligned with that purpose.

Install only if you want coding assistance for vvvv gamma .NET work. Expect the agent to suggest project-file edits, NuGet package sources, and build commands; review external feed URLs and any user-provided URLs before running code that downloads or loads remote content.

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
