Evaluate SEO keyword difficulty with the Authority Mark method instead of opaque keyword difficulty scores. Use when Codex needs to assess whether a user's domain can compete for a keyword by searching the live SERP, collecting the Ahrefs Domain Rating (DR) of the top organic ranking domains and the user's domain, identifying the first top-10 result whose DR is lower than the user's site, and explaining why this SERP-specific authority watermark is more actionable than a generic KD number.
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
# Authority Mark Keyword Difficulty ## Overview Use the Authority Mark method to judge keyword difficulty from the current SERP's authority floor. The core question is: "Is there already a top-10 organic result with lower Ahrefs DR than the user's domain, and at what rank does that happen?" ## Why This Is Valuable Traditional SEO keyword difficulty scores are compressed, proprietary estimates. They can be useful for sorting large keyword lists, but they hide the actual reason a keyword is hard: who is already ranking, how strong those domains are, and whether the user's site has enough authority to enter the visible SERP. Authority Mark is not another keyword difficulty score. It is a SERP-specific watermark: - It compares the user's domain against the actual top-ranking domains for the exact query. - It gives a concrete threshold, such as "position 7 is currently held by a lower-DR site." - It turns difficulty into an action decision: "there is an authority opening," "there may be an opening if the content is excellent," or "authority alone says this is probably not a near-term target." …

How to install
mdr add marketingskills/seo/authority-mark-keyword-difficulty@sha256:11ee230a36e8c1f0The line at the top of this page pins the label git:20260625.eb0d762, 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.
