# SubmitLLMs Comprehensive Platform Specification & Full Context Guide > SubmitLLMs is the premier AI Readiness, Discovery, and llms.txt Ecosystem Platform. We provide automated auditing, validation, generator tools, and a live index of 5,805+ verified websites optimized for ChatGPT, Claude, Perplexity, and autonomous AI search agents. --- ## 1. Executive Overview & Mission As artificial intelligence models (such as GPT-4, Claude 3.5, Gemini 1.5, DeepSeek, and Perplexity) increasingly mediate how users discover information, products, and developer tools, traditional search engine optimization (SEO) is evolving into Artificial Intelligence Engine Optimization (AIO). SubmitLLMs bridges this paradigm shift by: 1. Establishing standardized AI discoverability protocols (`/llms.txt`, `/llms-full.txt`, `agent.json`, and bot-friendly `robots.txt`). 2. Providing real-time audit tools that calculate a transparent, 100-point AI Readiness Quality Score for any domain on the web. 3. Maintaining an open, high-quality directory of verified AI-ready websites with structured profiles, dofollow backlinks, and dynamic SVG status badges. --- ## 2. The 100-Point AI Readiness Scoring Engine SubmitLLMs evaluates websites using an objective, unified 5-category scoring engine: ### Category 1: AI Discoverability (25 Points) - **robots.txt Present (10 pts)**: Verifies that `/robots.txt` is accessible via HTTPS. - **AI Search Bots Allowed (10 pts)**: Analyzes crawler permissions for primary AI user-facing bots (GPTBot, ClaudeBot, PerplexityBot, Applebot, Google-Extended). Points are awarded proportionally when AI agents are permitted to index public content. - **sitemap.xml Present (5 pts)**: Ensures search engines and crawlers have an XML index of public pages. ### Category 2: llms.txt Quality & Compliance (35 Points) - **File Presence (10 pts)**: `/llms.txt` is accessible at root and returns `text/plain` or `text/markdown`. - **H1 Title (# Name) (5 pts)**: Valid markdown top-level heading identifying the entity or project. - **Blockquote Summary (> Summary) (5 pts)**: Concise 1-2 sentence overview immediately following the H1. - **Structured Sections (## Heading) (5 pts)**: Logical grouping of documentation and navigation links. - **Markdown Hyperlinks ([Title](URL)) (5 pts)**: Standard markdown links with accompanying descriptive text. - **Sufficient Token Length (≥100 tokens) (5 pts)**: Ensures the file contains substantive summary data rather than placeholder stubs. ### Category 3: llms-full.txt Full Context Depth (15 Points) - **File Presence (10 pts)**: `/llms-full.txt` is accessible at root. - **Meaningful Documentation (≥500 tokens) (5 pts)**: Complete context documentation designed for deep model ingestion. ### Category 4: Autonomous Agent Protocols (15 Points) - **agent.json Presence (10 pts)**: `/.well-known/agent.json` or root `/agent.json` is accessible. - **Valid JSON Schema (5 pts)**: Validated against standard A2A (Agent-to-Agent) and MCP metadata schemas. ### Category 5: Technical Foundation & Performance (10 Points) - **HTTPS Enforcement (5 pts)**: Secure SSL/TLS transport. - **Response Latency (<2,000ms) (5 pts)**: Low latency delivery ensuring AI crawlers do not encounter timeouts. --- ## 3.
