shine-seo-audit

Run a lightweight SEO audit on a URL — routes to meta-inspector + lighthouse-dashboard + SERP check.

<objective> 1. Run `meta-inspector` on the URL (grade meta tags, OG, Twitter cards, JSON-LD). 2. Run a Lighthouse audit (via `lighthouse-dashboard` if installed, else raw `lighthouse` CLI). 3. Optional: fetch the SERP via Ahrefs MCP (if connected) for top 3 competing URLs. 4. Output a 1-page markdown report: current score, 5 prioritized fixes, effort estimate in MD. </objective>
