W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 0.80). The skill requires calling the external Rube MCP endpoint (https://rube.app/mcp) via RUBE_SEARCH_TOOLS to fetch tool slugs and schemas from that third-party server, and those returned, untrusted tool descriptions are explicitly read and used to decide which tools/arguments to execute, allowing indirect injection of instructions.
W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 0.90). Flagging https://rube.app/mcp because the skill requires adding that MCP server and at runtime calls RUBE_SEARCH_TOOLS / RUBE_MANAGE_CONNECTIONS to fetch tool schemas and recommended execution plans, which directly control agent prompts and tool execution.
