hreflang checker – a skill for Claude

Audits language and region versions and generates correct hreflang tags.

What it checks and does

• Invalid codes such as en-UK or en_US
• Missing self-reference and return links
• Missing x-default
• Canonical that cancels hreflang, alternates that don't exist

Try asking

“Check hreflang across ./dist (English, Spanish, German).”

Script

hreflang_check.py – Python 3.8+, standard library only, covered by the pack's tests. Claude runs it and reads only the output, so long files don't fill your context.

When Claude uses it

The skill's description, which Claude matches against your request:

Audit hreflang annotations on a multilingual or multi-regional site (HTML link tags or XML sitemap xhtml:link entries) for invalid language/region codes, missing self-references, missing return links, x-default, and conflicts with canonicals; then generate correct hreflang tags. Use when the user has an international/multilingual site, asks about hreflang, language versions showing in the wrong country, or "no return tags" errors.
