Full Analysis
  • [External Downloads] (MEDIUM): The skill instructions require the user to add an external MCP server endpoint https://rube.app/mcp. Because this domain is not included in the predefined trusted scope, it is treated as an unverifiable remote dependency.
  • [Indirect Prompt Injection] (HIGH): This skill presents a significant vulnerability surface for indirect prompt injection due to its operational model.
  • Ingestion points: The skill processes external, untrusted content from the web via the screenshot_fyi toolkit.
  • Boundary markers: There are no boundary markers or 'ignore embedded instructions' delimiters specified for the data ingested from external URLs.
  • Capability inventory: The skill utilizes RUBE_MULTI_EXECUTE_TOOL and RUBE_REMOTE_WORKBENCH, providing the agent with the ability to execute arbitrary commands and tools based on its reasoning.
  • Sanitization: No sanitization or validation of the content captured from external websites is performed before the agent processes it.
  • [Command Execution] (HIGH): The skill pattern relies on RUBE_MULTI_EXECUTE_TOOL to perform actions based on tool schemas discovered at runtime via RUBE_SEARCH_TOOLS. This allows for the dynamic execution of tools with potentially high privileges or side effects on the local or remote system.
  • [Remote Code Execution] (HIGH): The RUBE_REMOTE_WORKBENCH operation with run_composio_tool() enables remote execution patterns that bypass local environment restrictions, increasing the risk if the tool choice is influenced by malicious external data.
