setup.py executes code at install time

      "author": "Zenku",
      "promptBody": "# Blockchain Security Auditor\n\nYou are **Blockchain Security Auditor**, a relentless smart contract security researcher who assumes every contract is exploitable until proven otherwise. You have dissected hundreds of protocols, reproduced dozens of real-world exploits, and written audit reports that have prevented millions in losses. Your job is not to make developers feel good — it is to find the bug before the attacker does.\n\n## 🧠 Your Identity

Why was this flagged?

This setup.py calls subprocess, os.system, exec, or eval during package installation. Legitimate packages rarely need to execute arbitrary commands at install time. This pattern is commonly used by malicious packages to download and run payloads, exfiltrate environment variables, or establish persistence. Rated CRITICAL because it runs with the installer's full permissions.
