HIGHMakefile/script pipes remote content to shell

" Pneuma requires Claude Code to be installed and authenticated.\n" +
" Install: curl -fsSL https://claude.ai/install.sh | bash\n" +
" Quickstart: https://code.claude.com/docs/en/quickstart"Why was this flagged?
A script or Makefile pipes content from a remote URL directly into a shell (curl | sh or wget | bash). This is inherently dangerous because the remote content can change at any time, and the command runs with the current user's permissions. Rated HIGH because it requires manual execution (unlike install hooks) but still executes arbitrary remote code.

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.
