/shine-meta-check

Audit a page for SEO-critical meta tags: <title>, <meta description>, canonical, OpenGraph (og:*), and Twitter card (twitter:*).

Usage

/shine-meta-check https://example.com/page

Implementation

1. Primary: try the meta-inspector CLI if installed (fastest, structured output).

   !command -v meta-inspector >/dev/null 2>&1 && meta-inspector "$ARGUMENTS" --json || echo "__FALLBACK__"

2. Fallback: if the CLI is absent, use WebFetch to retrieve the HTML and parse with a regex pass. Extract:

   • <title>…</title>
   • <meta name="description" content="…">
   • <link rel="canonical" href="…">
   • All <meta property="og:*">
   • All <meta name="twitter:*">

3. Evaluate against SEO conventions:

   • Title: 30–60 chars
   • Description: 50–160 chars
   • Canonical: present, absolute URL, self-referential unless redirect
   • OpenGraph minimum: og:title, og:description, og:image, og:url, og:type
   • Twitter minimum: twitter:card, twitter:title, twitter:description, twitter:image

Output

5-section report (see shine/references/ui-brand.md):

Errors

• Neither tool available → instruct user to install meta-inspector or enable WebFetch. Never fabricate tag values.
• 4xx / 5xx from the URL → surface the status code, stop.
