recommendation=(Why was this flagged?
This package overrides Python's setup.py cmdclass, which allows arbitrary code to execute during pip install. This is the primary attack vector for malicious PyPI packages — attackers use it to steal credentials, install backdoors, or download additional payloads before the developer ever runs the code. Rated CRITICAL because it executes automatically with no user interaction required.

(curl | sh, wget | bash, base64 -d | bash, etc.)
"""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.

npm lifecycle scripts like postinstall run automatically during package installation with no user interaction required. This is the #1 attack vector for malicious npm packages — attackers embed data theft or backdoor installation in these hooks. Rated CRITICAL because code executes before the developer can review it.
