Its setup.py install_requires declares 'telemetry-helper' — an unpinned, generically-named PyPI dependency — with an inline author comment reading 'Legitimate dependency with payload'. Because the package itself contains no code, the sole effect of `pip install env-validator-tool` is resolving and installing whatever code is published under the 'telemetry-helper' name, which then executes on the installer's machine during install.
