Also covers translating Content Collections per locale and adding hreflang alternate links via @astrojs/sitemap's i18n option for SEO. Does not cover general SEO meta tags beyond hreflang (astro-seo) or the Content Layer API itself (astro-content) — this skill focuses specifically on locale routing and URL generation.

Astro i18n

Agent Workflow (MANDATORY)

Before ANY implementation, spawn 3 agents in parallel, one Agent call each with a name:

1. fuse-ai-pilot:explore-codebase - Analyze existing routing, content collections, and locale files
2. fuse-ai-pilot:research-expert - Verify latest Astro i18n docs via Context7/Exa
3. mcp__context7__query-docs - Check astro:i18n API and sitemap integration

After implementation, run fuse-ai-pilot:sniper for validation.
