llms.txt Architecture: Structuring Documentation for Autonomous AI Agents

The `llms.txt` file acts as the modern `robots.txt` for AI agent consumption. Rather than blocking access, it curates high-density markdown documents that LLM agents can ingest to understand a project's architecture rapidly.

Key Sections of a Compliant llms.txt

A well-architected `llms.txt` includes a project mission statement, an enumerated list of core modules with brief descriptions, and direct URLs to raw markdown documentation files. This ensures zero parsing friction for autonomous AI crawlers.
