What problem does it solve? Building a production marketing site involves dozens of disconnected setup tasks — scaffolding, SEO tags, sitemaps, analytics, image optimization, and performance tuning — that are easy to forget or misconfigure. This Skill runs the entire site-building workflow as one ordered pipeline, detecting what already exists and only executing what is missing. ## Core Features & Use Cases - Full pipeline orchestration: Runs foundation, favicon, meta tags, robots.txt, sitemap, IndexNow, analytics, prerendering, image, and Lighthouse performance skills in sequence. - Dual framework tracks: Supports Vite + React on Firebase Hosting and Next.js App Router on Firebase App Hosting, with per-track detection rules and conventions. - Create and upfit modes: Builds a new site from a design export (or a Hello World scaffold), or audits an existing repo and patches only missing pieces. - Optional feature menu: Adds transactional email via Resend, Stripe payments, Reddit pixel, multilingual support, ad landing pages, SEO blog, compare pages, and reCAPTCHA on demand. - Use Case: Point the skill at a design export zip, answer a few intake questions (name, domain, framework), and receive a deployed, SEO-optimized, Lighthouse-tested marketing site on Firebase. ## Quick Start Run /senternet-create-site with the path to your design export zip or an existing site directory to build or upfit a complete optimized marketing site.
