Graduation rationale

Checks AI-native markdown for `pip install` examples that point package discovery at `http://` find-links sources.

Deterministic signal basis

MarkdownSignals exact `pip install` token analysis with `--find-links http://`, `--find-links=http://`, or `-f http://` detection inside parsed markdown regions.

Structural stable rule positioned as a supply-chain hardening control: high-precision and actionable, but not a blanket claim of direct repository compromise.

SEC456 / MD-PIP-HTTP-FIND-LINKS ​

SEC456 flags AI-native markdown when a pip install example uses --find-links http://..., --find-links=http://..., or -f http://....

Why It Matters ​

pip install --find-links http://... points package discovery at an insecure transport. In shared AI-native instructions, that turns an integrity-bypassing supply-chain pattern into copy-pastable setup guidance.

What Triggers It ​

  • AI-native markdown surface
  • the same parsed markdown region contains a matching pip install, pip3 install, or python -m pip install form
  • the same region also contains one of:
    • --find-links http://
    • --find-links=http://
    • -f http://

The finding points to http://.

What Does Not Trigger It ​

  • https:// find-links sources
  • --index-url http://... and --extra-index-url http://... because those are covered by SEC449
  • unrelated prose that mentions http:// outside a matching pip install form

Example ​

Bad:

bash
pip install --find-links http://packages.example.test/simple demo

Better:

bash
pip install --find-links https://packages.example.test/simple demo

Remediation ​

Replace the insecure http:// find-links source with a normal TLS-verified https:// source.
