authority-mark-keyword-difficulty skillA

authority-mark-keyword-difficulty is agent-read markdown (skill) from marketingskills/seo: 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..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
