Site Generation

15 — Site Generation

Run the end-to-end AI website generation pipeline: research→media→Bolt artifact emission→R2 upload→D1 status for all business types.

Model migration note (pass-78, 2026-06-09): DALL-E → GPT Image 1.5 + GPT-4o → GPT Image 2 vision. Per platform.openai.com/docs/deprecations. Generation pipeline unchanged.

Dual-Template Architecture (TWO REPOS — NEVER CONFUSE)

• Local Business: megabytespace/template.projectsites.dev — Vite + React + Tailwind + shadcn/ui, 15 local components, CSS var brand slots. Use for: restaurant, salon, medical, legal, fitness, contractor, retail, etc.
• SaaS: megabytespace/saas-starter — Hono + D1 + Clerk + Stripe + Inngest + Resend on CF Workers. Use for: SaaS products, APIs, dev tools, platforms.

Template selection (from _form_data.json.category)

• restaurant|cafe|salon|spa|medical|dental|legal|fitness|automotive|construction|photography|real_estate|education|financial|retail|pet_services|wedding|church|nonprofit|government → template.projectsites.dev
• saas|api|platform|devtool|marketplace → saas-starter
• Unknown → local business

Auto-sync

After ANY change to skills 05-15, evaluate: "Does this improve template?" If yes → push to appropriate template repo same prompt.

Generation Protocol

Model emits ONE <boltArtifact> XML envelope with ordered <boltAction type="file" filePath="…"> and <boltAction type="shell"> actions. See bolt-artifact-protocol.md.

• First action ALWAYS PLAN.md (route tree, design-token diff, media count, file count, validators)
• Runtime parser validates first-action-is-PLAN.md + required-files + npm…build shell action; failures re-prompt (max 2 retries)
• Executor modes: container (default — git clone template → npm install → vite build → upload dist/) | r2-files (pre-built static)

Pipeline

Phase 0: Pre-Research + Media Acquisition (ALL BUILD MODES)
  → Google Places, scraping, social verification, brand extraction, media discovery
  → Download ALL images from original; stock via Pexels/Pixabay; AI via GPT Image 1.5 / Stability AI
  → YouTube/Pexels video embeds
  → Output: _research.json, _scraped_content.json, _assets/
  → HARD GATE: <10 images = build NOT complete

Phase 1: Claude Opus 4.8 Bolt-Artifact Emission (Worker OR Container)
  → Reads all _ context files; emits ONE <boltArtifact> envelope
  → First action ALWAYS PLAN.md
  → Customizes pre-installed Vite+React+Tailwind+shadcn/ui template
  → Builds 1:N-page site MATCHING source sitemap (every URL recreated, max 1000)
  → Clean URL slugs (never copy CMS garbage like -1 suffixes)

Phase 2: Post-Build Verification (Worker)
  → Screenshot via microlink.io → GPT Image 2 vision scoring
  → D1 status update → email notification

CRITICAL — In manual/prompt-based builds (no container), Phase 0 runs INLINE as first step. Agent MUST: (1) WebFetch original site pages + extract all image URLs; (2) download images to public/; (3) search + download stock photos; (4) generate AI images if API keys available. ALL BEFORE writing any React code. Text-only site = failed build.

Context Files (written before model runs)

• _research.json — business profile + hours + phone + address + reviews + geo
• _brand.json — colors + fonts + personality + logo URL + color_source
• _citations.json — APA 7th bibliography keyed by refId per citations.md
• _scraped_content.json — all pages by URL
• _assets.json — image manifest w/ metadata
• _image_profiles.json — GPT Image 2 vision analysis per image: quality + placement + colors
• _videos.json — YouTube/Pexels embed URLs + metadata
• _places.json — Google Places enrichment: photos + reviews + rating
• _form_data.json — user-submitted from /create
• _domain_features.json — category-specific feature requirements

Build Rules (NON-NEGOTIABLE)

Images

• USE ALL images in assets/. Never external URLs (hotlinking blocked).
• Hero: assets/hero-*. Gallery: full-width slider w/ ALL images. No image left unused.
• Minimum count: max(30, original_image_count × 1.4, page_count × 6_home_or_4_sub) — 4-page rebuild ⇒ 30-50 images; 50-page ⇒ 200+; 500-page ⇒ 2000+
• Per-page floor: home ≥6, every sub-page ≥4. Minimum 5 AI-generated GPT Image 1.5 originals per site.
• All images through optimization pipeline (skill 12): WebP + AVIF at 320/640/1280/1920w, blur placeholders, dominant color extraction. Use <ResponsiveImage>, never raw <img> w/ PNG/JPG src.
• Dedupe via 301 not deletion — md5-hashed twins keep canonical, emit {deleted-url:canonical} to Worker redirect map.

Video

• Walker captures <video> + <source> + <iframe src*=youtube|vimeo|wistia|loom> + data-video-id + CSS background-video + autoplay-loop hero MP4s + animated WebPs + lottie .json
• Output _videos.json keyed by source URL w/ {src, poster, duration, dims, transcript?, captions_vtt?, original_route, slot_hint}
• Template's <VideoEmbed> lazy-loads, poster-first, captions if VTT exists, respects prefers-reduced-motion
• Augment via Pexels Video API (free) + YouTube Data API search-by-topic for missing background loops
• Video count gate: every original <video> and embed accounted for in _videos.json; missing = fail

GPT Image 1.5 Purpose-Craft (per-slot prompts — never generic)

Every AI-generated image brief MUST include: (1) route + section (/about hero); (2) page topic + intent; (3) brand palette tokens by hex from _brand.json; (4) composition + aspect ratio; (5) subject specificity (named noun + modifiers + lighting + lens metaphor); (6) negative prompt (no text, no watermarks, no AI artifacts, no extra fingers, no logos).

Build _image_briefs.json per site BEFORE generation — one brief per slot, reused across fallback chain (GPT Image 1.5 → Ideogram → Recraft). Generic "create a hero image" = fail; discarded + brief regenerated.

Per-Route SEO

SPAs swap meta on useLocation() change via <PageHead /> reading src/data/page-meta.ts. Each entry: title 50-60ch keyphrase-first | desc 120-156ch | canonical + og:+ twitter: + JSON-LD (Org/Service/BlogPosting/BreadcrumbList/FAQPage). Hard gate: every <Route path> has page-meta.ts entry or data-derived meta.

Font-Flash Mitigation

index.html <head>: <link rel="preload" as="style"> + animate.css + html:not(.fonts-loaded) body { opacity: 0 } + inline document.fonts.ready.then(reveal) + setTimeout(reveal, 1200) safety net.

Hero Context Match

Every hero image/video literally depicts page topic — /mass-schedule gets stained-glass-window, /donate gets volunteers-serving. AI-vision QA scores image_matches_page_topic 0-10 per hero; <8 = replace.

Empty-Config Widgets

Gate every third-party widget on env var: {import.meta.env.VITE_TURNSTILE_SITEKEY ? <div className="cf-turnstile" data-sitekey={...} /> : null}. Same for Stripe pk, PostHog snippet, Resend embed. Empty data-sitekey="" = console error on every render.

Post-Deploy Parallel Scan (BOTH scripts required — deploy not verified without both)

• scripts/scan-assets.mjs — Playwright concurrency 6, captures console errors/warnings + requestfailed + response.status>=400 per route
• scripts/check-routes.sh — curl every route + every blog slug for non-200

Design

• Dark-first, brand-extracted base color (skill 10 — MANDATORY) | 10+ @keyframes animations
• Glassmorphism cards (bg-white/5 backdrop-blur-md border-white/10) | gradient text on key headings
• Parallax-style depth on hero | 25+ inline SVG decorative elements
• Every interactive element has hover + active + focus states
• Smooth scroll for ALL same-page nav (scrollIntoView, never #href jumps)

Content

• Word count MATCH OR EXCEED original — never ship less content; 5000+ words minimum
• Migrate ALL blog posts, news, events, team bios from scraped content
• About page 2000+ words | every claim factually accurate from research
• Blog → individual routes per post with RSS feed
• Addresses → Google Maps links | phone → tel: links | email → mailto: links
