hreflang-international skillA

hreflang-international is agent-read markdown (skill) from nowork-studio/notfair-plugin: International / multilingual SEO audit focused on hreflang correctness. Detects and diagnoses the most common (and ranking-damaging) hreflang mistakes: missing or broken return tags, wrong language/region codes, missing x-default, self-referencing errors, conflicts between hreflang and canonical, and inconsistent signals across HTML head / HTTP headers / XML sitemap. Also reviews the broader international setup — URL structure (ccTLD vs subdirectory vs subdomain), language targeting, and geo sig.

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.

How to install

Latest version
mdr add nowork-studio/notfair-plugin/hreflang-international@git:20260721.5584e52
Exact content
mdr add nowork-studio/notfair-plugin/hreflang-international@sha256:8364f78eb44fdb70

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
