Graduation rationale

Checks AI-native markdown for `cargo install` examples that fetch a crate directly from an `http://` git source.

Deterministic signal basis

MarkdownSignals exact `cargo install` token analysis with `--git http://` detection inside parsed markdown regions.

SEC451 / MD-CARGO-HTTP-GIT-INSTALL ​

SEC451 flags AI-native markdown when a cargo install example uses --git http://... or --git=http://....

Why It Matters ​

cargo install --git http://... removes normal TLS protection from crate source retrieval. In shared AI-native instructions, this turns an insecure supply-chain pattern into copy-pastable setup guidance.

Trigger Shape ​

The rule triggers only when all of these are true:

  • a parsed markdown region contains cargo install
  • the same region also contains either --git http:// or --git=http://

The finding points to http://.

Clean Cases ​

  • cargo install --git https://...
  • cargo install examples without --git http://
  • unrelated prose that mentions http:// outside a matching cargo install form

Trigger Example ​

bash
cargo install --git http://git.example.test/demo.git

Safer Example ​

bash
cargo install --git https://git.example.test/demo.git

Remediation ​

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