+# AEO Toolkit — Answer Engine Optimization
+
+Build Answer Engine Optimization into an existing project so AI crawlers (GPTBot, ClaudeBot, PerplexityBot) can discover, parse, and cite the site's content.
+
+## Overview
+
+An AEO (Answer Engine Optimization) implementation that ralph drops into the user's existing project. Ralph first reads `package.json` to detect the framework (Next.js, Nuxt, Astro, Remix, Express, or static), then generates only the files that match that stack. The toolkit covers the core AEO primitives: `robots.txt` with AI crawler directives, `llms.txt` / `llms-full.txt` per the llmstxt.org spec, AI-optimized sitemaps, structured data (JSON-LD) tuned for answer extraction, and a CLI auditor that scores the site's AEO readiness.
+
+AI crawlers do not execute JavaScript — all critical content must be in the initial HTML response. This is the fundamental constraint the toolkit addresses.
+
+## Features
+
+- Framework auto-detection from `package.json`
+- `robots.txt` with AI crawler directives (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot)
+- `llms.txt` and `llms-full.txt` generation per llmstxt.org spec
+- AI-optimized XML sitemap with priority scoring
+- JSON-LD structured data (Article, FAQ, HowTo, Product, Organization)
+- Bot detection middleware (identifies AI crawlers by user-agent)
+- Markdown endpoint support (`.md` versions of pages for LLM consumption)
+- AEO audit CLI that scores a site 0-100
+- Entity consistency checker
+
+## Tasks
+
+### Task 1: Detect Framework and Setup
+
+- [ ] Read `package.json` to detect framework (next, nuxt, astro, remix, express)
+- [ ] Create `aeo.config.ts` with Zod-validated schema (site name, URL, crawler policies)
+- [ ] Create `src/lib/aeo/` directory for core utilities
+- [ ] Install dependencies (zod, unified/remark, xml2js)
+
+### Task 2: robots.txt with AI Crawler Directives
+
+- [ ] Generate `robots.txt` using the detected framework's routing pattern
+- [ ] Include directives for: GPTBot, ChatGPT-User, ClaudeBot, Claude-Web, PerplexityBot, Google-Extended, CCBot, Meta-ExternalAgent, Bytespider, Applebot-Extended
+- [ ] Support three policies via config: `allow-all`, `block-training`, `selective`
+- [ ] Add Sitemap and Crawl-delay directives
+- [ ] Write tests
+
+### Task 3: llms.txt and llms-full.txt
+
+- [ ] Generate `llms.txt` from config content map (H1 title, blockquote summary, H2 link sections)
+- [ ] Generate `llms-full.txt` with full site documentation (company overview, products, audience)
+- [ ] Serve both files via the framework's routing system
+- [ ] Add `lastUpdated` timestamp
+- [ ] Write tests
+
+### Task 4: AI-Optimized Sitemap
+
+- [ ] Generate XML sitemap with priority scoring (landing pages > docs > blog > archives)
+- [ ] Add `lastmod` timestamps and `changefreq` hints
+- [ ] Reference sitemap in robots.txt
+- [ ] Write tests
+
+### Task 5: Structured Data (JSON-LD)
+
+- [ ] Create JSON-LD generator functions: Article, FAQ, HowTo, Product, Organization, BreadcrumbList
+- [ ] Create component/helper to inject `<script type="application/ld+json">` into pages
+- [ ] Add schema validator utility
+- [ ] Write tests for each schema type
+
+### Task 6: Bot Detection Middleware
+
+- [ ] Create `isAIBot(userAgent)` utility with patterns for all known AI crawlers
+- [ ] Create middleware that tags AI bot requests (sets header or context flag)
+- [ ] Add HTML meta tags: `<meta name="robots" content="max-snippet:-1, max-image-preview:large">`
+- [ ] Add canonical URL helper
+- [ ] Write tests
+
+### Task 7: Markdown Endpoints
+
+- [ ] Create middleware/route to serve `.md` versions of pages
+- [ ] Convert HTML to clean markdown (strip nav, footer, boilerplate)
+- [ ] Add front-matter metadata (title, description, date)
+- [ ] Write tests
+
+### Task 8: AEO Audit CLI
+
+- [ ] Create `scripts/aeo-audit.ts` runnable via `npx tsx scripts/aeo-audit.ts`
+- [ ] Check: robots.txt has AI bot directives, llms.txt exists and is valid, structured data present, critical content is in static HTML
+- [ ] Score 0-100 with actionable recommendations
+- [ ] Output as terminal table
+- [ ] Write tests
+
+### Task 9: Entity Consistency Checker
+
+- [ ] Define entity registry in config (brand names with canonical forms and variants)
+- [ ] Scan source files for inconsistent naming
+- [ ] Report with file locations and suggested fixes
+- [ ] Write tests
+
+## Tech Stack
+
+- TypeScript
+- Zod (config validation)
+- Unified / Remark (markdown processing)
+- xml2js (XML generation)
+- Vitest (testing)
+- Framework detected at generation time from `package.json`
+
+## Files to Create
+
+- `aeo.config.ts`
+- `src/lib/aeo/config.ts`
+- `src/lib/aeo/robots.ts`
+- `src/lib/aeo/llms-txt.ts`
+- `src/lib/aeo/sitemap.ts`
+- `src/lib/aeo/structured-data.ts`
+- `src/lib/aeo/bot-detector.ts`
+- `src/lib/aeo/markdown-endpoints.ts`
+- `src/lib/aeo/entity-checker.ts`
+- `scripts/aeo-audit.ts`
+- `tests/aeo/robots.test.ts`
+- `tests/aeo/llms-txt.test.ts`
+- `tests/aeo/structured-data.test.ts`
+- `tests/aeo/bot-detector.test.ts`
+- `tests/aeo/audit.test.ts`
+
+## Files to Modify
+
+- `package.json` — Add dependencies
+- Framework-specific routing files (detected at generation time) — Wire robots.txt, llms.txt, sitemap routes
+
+## Configuration
+
+### aeo.config.ts
+
+```typescript
+import { defineAEOConfig } from './src/lib/aeo/config';
+
+export default defineAEOConfig({
+  site: {
+    name: 'My Company',
+    url: 'https://example.com',
+    description: 'Short description for llms.txt blockquote',
+  },
+  robots: {
+    policy: 'allow-all', // 'allow-all' | 'block-training' | 'selective'
+  },
+  llmsTxt: {
+    sections: [
+      { title: 'Documentation', pages: ['/docs', '/guides'] },
+      { title: 'Blog', pages: ['/blog'] },
+    ],
+  },
+  entities: {
+    'Next.js': ['NextJS', 'Next JS', 'Nextjs'],
+  },
+});
+```
+
+## Notes
+
+- Ralph reads `package.json` to detect the framework and generates routes/middleware using that framework's patterns
+- AI crawlers do NOT execute JavaScript — all critical content must be in the initial HTML
+- `llms.txt` is an emerging standard (not yet formally adopted by major AI companies) but is low-risk to implement
+- `robots.txt` remains the primary mechanism for AI crawler control
+- ChatGPT crawls ~8x more than Googlebot; Perplexity ~3x (Conductor research)
+- Requires Node.js 18+

+# SEO Toolkit — Technical SEO
+
+Build technical SEO into an existing project covering metadata, structured data, sitemaps, performance monitoring, and on-page optimization.
+
+## Overview
+
+A Technical SEO implementation that ralph drops into the user's existing project. Ralph first reads `package.json` to detect the framework (Next.js, Nuxt, Astro, Remix, Express, or static), then generates only the files that match that stack. Covers every pillar of modern SEO: metadata management, Open Graph / Twitter Cards, canonical URLs, structured data (JSON-LD), XML sitemaps, RSS feeds, robots.txt, and an SEO audit CLI that scores the site.
+
+While the AEO Toolkit focuses on AI answer engines, this toolkit targets traditional search engines (Google, Bing) and social platforms (Facebook, Twitter/X, LinkedIn).
+
+## Features
+

+- XML sitemap generation
+- RSS / Atom feed generation
+- Dynamic `robots.txt`
+- Heading hierarchy validator
+- Image alt text auditor
+- Internal linking analyzer with orphan page detection
+- SEO audit CLI that scores a site 0-100

+- [ ] Create framework-specific integration (Next.js Metadata API, Nuxt useHead, etc.)
+- [ ] Write tests
+
+### Task 3: Structured Data (JSON-LD)
+
+- [ ] Create JSON-LD generator functions: WebSite, Organization, Article, Product, BreadcrumbList, LocalBusiness, FAQPage

+- [ ] Return structured report with issues and locations
+- [ ] Write tests
+
+### Task 7: Image Alt Text Auditor
+
+- [ ] Create `auditImages(html)` — detects missing or generic alt text
+- [ ] Flag missing `width`/`height` attributes (CLS risk)
+- [ ] Generate image sitemap entries
+- [ ] Write tests
+
+### Task 8: Internal Linking Analyzer
+
+- [ ] Create `analyzeLinkGraph(pages)` — build link graph from page list
+- [ ] Detect orphan pages (no internal links pointing to them)
+- [ ] Calculate link depth from homepage
+- [ ] Flag broken internal links (404s)
+- [ ] Write tests
+
+### Task 9: SEO Audit CLI
+
+- [ ] Create `scripts/seo-audit.ts` runnable via `npx tsx scripts/seo-audit.ts`
+- [ ] Check: meta tags, OG tags, canonical URLs, structured data, headings, images, robots.txt
+- [ ] Category scores: Metadata, Structured Data, Content, Crawlability
+- [ ] Score 0-100 with prioritized recommendations (critical, warning, info)
+- [ ] Output as terminal table and optional JSON
+- [ ] Write tests

+  structuredData: {
+    organization: {
+      name: 'My Company',
+      logo: 'https://example.com/logo.png',
+      sameAs: ['https://twitter.com/mycompany', 'https://github.com/mycompany'],

+  ],
+});
+```
+
+## Notes
