hreflang-international

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 signals. Use this skill whenever the user runs a multi-language or multi-region site and asks about hreflang, international SEO, multilingual SEO, the wrong-language page showing in search, duplicate-content across country versions, or "th/en page ranking in the wrong country". Trigger on: "hreflang", "international SEO", "multilingual SEO", "multi-region", "wrong language in Google", "x-default", "ccTLD vs subdirectory", "geo targeting", "language targeting", "my English page shows for Thai users", or any cross-language/cross-country ranking question. For full-site audits use /seo-analysis; for a single URL use /seo-page.

Low

W011: Third-party content exposure detected (indirect prompt injection risk).

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

This skill’s required workflow instructs the agent to ingest and analyze externally fetched site content (the user-supplied `$SITE_URL` and its HTML/HTTP headers/sitemaps for representative URLs) to extract hreflang text at runtime, which is outsider-authored free text.
