CRITICAL

setup.py executes code at install time

molecule_ai_workspace_runtime-0.1.0/molecule_runtime/cli_executor.py:86

    # Auth via GEMINI_API_KEY env var; MCP is wired via ~/.gemini/settings.json
    # (not --mcp-config) — the adapter's setup() handles that step.
    # System prompt is seeded into GEMINI.md (equivalent of CLAUDE.md).

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.
