SEC448 / MD-PIP-TRUSTED-HOST ​

SEC448 flags AI-native markdown when a pip install example uses the exact --trusted-host option.

Why It Matters ​

--trusted-host weakens the normal trust model for Python package retrieval. In shared AI-native instructions, that turns a risky supply-chain workaround into copy-pastable team guidance.

Trigger Shape ​

The rule triggers only when all of these are true:

  • the file is an AI-native markdown instruction surface
  • a parsed markdown region contains pip install, pip3 install, or python -m pip install
  • the same region also contains the exact token --trusted-host

Clean Cases ​

These stay clean:

  • pip install examples without --trusted-host
  • examples that use a normal HTTPS index URL
  • unrelated commands that mention --trusted-host without pip install

Example Trigger ​

bash
pip install --trusted-host pypi.example.test demo

Safer Example ​

bash
pip install --index-url https://pypi.example.test/simple demo

How To Fix ​

Remove --trusted-host and use a normal TLS-verified Python package source instead.
