Wan 3.0 Video Prompt Architect

Security checks for vulnerabilities and agentic risk

Overview

The skill is mainly a prompt-writing guide, but its optional setup tells users to run unpinned remote GitHub code locally, so it should be reviewed before installation.

Install the markdown skill only if you are comfortable using it as prompt-writing guidance. Treat the optional MCP setup separately: review the GitHub repository and dependency tree first, prefer a pinned commit or verified release, and run it with limited filesystem, environment, credential, and network access. Remove or avoid the MCP configuration if you only need prompt drafting.

A.I.G

Vulnerability Patterns
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • 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
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Finding

The skill instructs users to install and run an MCP server directly from a GitHub reference via npx -y github:... without pinning to an immutable version, tag, or commit. That creates a supply-chain risk: if the upstream repository is changed or compromised, users may execute attacker-controlled code locally when following the documented setup steps.

Finding

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.
