Risk Level: MEDIUM
Full Analysis
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 0.80). This skill instructs the agent to call RUBE_SEARCH_TOOLS against an external MCP server (https://rube.app/mcp) to retrieve tool slugs, input schemas and execution plans—untrusted third-party content the agent is expected to read and act on, enabling indirect prompt injection.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 0.90). The skill requires using the external MCP endpoint https://rube.app/mcp at runtime (via RUBE_SEARCH_TOOLS and RUBE_MULTI_EXECUTE_TOOL), and the responses from that endpoint provide tool schemas that directly determine agent actions and execute remote tools, making it a required runtime dependency.
