### AUDIT SCOPE:

1. **Frontmatter**: Valid `name: technical-seo-auditor` and description specifying when Claude should perform crawl simulations, metadata audits, and indexing diagnostics.
2. **Audit Checkpoints to Implement**:
   - **Canonical Tag Hygiene**: Self-referencing canonicals on all canonical pages; parameter stripping; trailing slash consistency.
   - **Open Graph & Twitter Cards**: og:title, og:description, og:image (1200x630px absolute URLs), og:url.
   - **Structured Data / JSON-LD**: Organization, WebSite, BreadcrumbList, Article, and Service schemas with zero validation warnings.
   - **Robots.txt & XML Sitemap**: Sitemap URL discovery, disallow rules, valid sitemap XML formatting with accurate `<lastmod>`.
   - **Hreflang & International SEO**: Bidirectional hreflang links and `x-default` implementation across supported languages.
   - **Core Web Vitals & Assets**: Responsive image srcset, lazy loading, font preloading, layout shift guards.
3. **Execution Steps**:
   - Step 1: Scan all HTML/template files in the workspace.
   - Step 2: Validate metadata tags against search engine guidelines.
   - Step 3: Run Node.js audit script to detect broken internal links and missing schemas.
   - Step 4: Output structured SEO Remediation Report (Critical, Warning, Optimization).
4. **Quality Checks & Constraints**: Never add duplicate tags, verify absolute URLs in sitemaps, validate schema syntax against schema.org.
