Ruofan Bargain Arena

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed bargaining-game integration that sends user-provided nickname and messages to the stated Ruofan API and does not show hidden persistence or local system access.

Install only if you are comfortable sending a nickname and bargaining messages to Ruofan's website for this promotion. Avoid sharing private information in the bargain text, since the skill says the process may be publicly displayed.

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