Use when auditing a site's internal and external links for protocol consistency, migrating a site from HTTP to HTTPS, or reviewing hardcoded URLs in a codebase that may use `http://` instead of `https://`.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Do not link from HTTPS to HTTP Linking from a secure HTTPS page to an HTTP destination creates a mixed content situation that browsers warn users about or block entirely. It also means the linked page does not receive the ranking signal passed through the HTTPS referrer. For internal links, it can cause redirect loops or broken navigation. ## Quick Reference - All internal links on an HTTPS page must point to HTTPS URLs — HTTP links trigger mixed content warnings - External links to HTTP destinations break the security chain and may be blocked by browsers - Use protocol-relative URLs (`//example.com`) or absolute HTTPS URLs — never hardcode `http://` for internal links ## Check On pages served over HTTPS, scan all `<a href>` attributes for URLs starting with `http://` (not `https://`). Flag: (1) Internal links using `http://` that should use `https://` or a relative path. (2) External links to third-party sites still on HTTP (flag for review — the destination may not support HTTPS). (3) Resource links (`<img src>`, `<script src>`, `<link href>`) pointing to HTTP URLs — these cause active mixed content warnings. ## Fix …

How to install
mdr add thedaviddias/front-end-checklist/https-downgrade@sha256:da858d10fd4cea08The line at the top of this page pins the label git:20261004.4b0ddb9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
