LLM.txt & AI Crawler Setup Guide for AI SaaS Builders

Create a text file at `/ai-agents.txt` with a concise overview of your AI SaaS's core functionality and data domains.

Include markdown-style links to critical API documentation, SDK repositories, and foundational knowledge base articles.

Add a 'Capabilities' section in the file to explicitly list supported AI tasks (e.g., 'Text Generation', 'Data Analysis', 'Code Synthesis') and associated data formats.

Define granular access policies using `User-agent:` directives for known AI agents (e.g., `User-agent: Devin`, `User-agent: ChatGPT-API-Crawler`) and custom agent identifiers.

Implement `Allow:` and `Disallow:` rules based on data sensitivity, API rate limits, and functional scope (e.g., `Allow: /api/v1/embeddings/`, `Disallow: /internal/training-data/`).

Utilize an API gateway or middleware to enforce these `ai-agents.txt` directives programmatically and log all agent access attempts for auditing.

Wrap distinct AI model features and their parameters within `<section>` tags, using `aria-label` attributes to define the feature name (e.g., `aria-label='LLM Fine-Tuning API'`).

Employ `JSON-LD` schema markup for `SoftwareApplication` and `APIReference` to detail model versions, input/output schemas, and functional parameters.

Ensure all tabular data, especially for API pricing or performance benchmarks, uses `<thead>`, `<tbody>`, and `<th>` for unambiguous data extraction by agents.

Maintain conceptual coherence within logical content blocks, ideally under 750 tokens, focusing on single AI concepts or API functionalities.

Prepend each chunk with a clear, concise summary of its primary subject matter to mitigate context drift for retrieval systems.

Eliminate ambiguous pronouns and generic references; explicitly name AI models, features, parameters, or data entities (e.g., 'The `text-davinci-003` model' instead of 'It').
