2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
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.
Third-party content exposure detected (high risk: 0.90). This skill explicitly requires calling the external MCP server (https://rube.app/mcp) via RUBE_SEARCH_TOOLS to ingest tool schemas and "recommended execution plans" which the agent must read and use to construct RUBE_MULTI_EXECUTE_TOOL calls, so untrusted third‑party responses could materially influence actions.
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.
Potentially malicious external URL detected (high risk: 0.80). The skill requires contacting the MCP endpoint https://rube.app/mcp at runtime to fetch tool schemas and recommended execution plans that directly determine prompts/arguments and tool executions, making this a required external dependency that controls agent behavior.
