Create LLMs.txt File from Repository Structure

Create a new llms.txt file from scratch in the root of the repository following the official llms.txt specification at https://llmstxt.org/. This file provides high-level guidance to large language models (LLMs) on where to find relevant content for understanding the repository's purpose and specifications.

Primary Directive

Create a comprehensive llms.txt file that serves as an entry point for LLMs to understand and navigate the repository effectively. The file must comply with the llms.txt specification and be optimized for LLM consumption while remaining human-readable.

Analysis and Planning Phase

Before creating the llms.txt file, you must complete a thorough analysis:

Step 1: Review llms.txt Specification

• Review the official specification at https://llmstxt.org/ to ensure full compliance

• Understand the required format structure and guidelines

• Note the specific markdown structure requirements

Step 2: Repository Structure Analysis

• Examine the complete repository structure using appropriate tools

• Identify the primary purpose and scope of the repository

• Catalog all important directories and their purposes

• List key files that would be valuable for LLM understanding

Step 3: Content Discovery

• Identify README files and their locations

• Find documentation files (.md files in /docs/, /spec/, etc.)

• Locate specification files and their purposes

• Discover configuration files and their relevance

• Find example files and code samples

• Identify any existing documentation structure

Step 4: Create Implementation Plan

Based on your analysis, create a structured plan that includes:

• Repository purpose and scope summary

• Priority-ordered list of essential files for LLM understanding

• Secondary files that provide additional context

• Organizational structure for the llms.txt file

Execution Steps

Step 1: Repository Analysis

• Examine the repository structure completely

• Read the main README.md to understand the project

• Identify all documentation directories and files

• Catalog specification files and their purposes

• Find example files and configuration files

Step 2: Content Planning

• Determine the primary purpose statement

• Write a concise summary for the blockquote

• Group identified files into logical categories

• Prioritize files by importance for LLM understanding

• Create descriptions for each file link

Step 3: File Creation

• Create the llms.txt file in the repository root

• Follow the exact format specification

• Include all required sections

• Use proper markdown formatting

• Ensure all links are valid relative paths

Step 4: Validation

• Verify compliance with https://llmstxt.org/ specification

• Check that all links are valid and accessible

• Ensure the file serves as an effective LLM navigation tool

• Confirm the file is both human and machine readable

Quality Assurance

Format Validation

• ✅ H1 header with project name

• ✅ Blockquote summary (if included)

• ✅ H2 sections for file lists

• ✅ Proper markdown link format

• ✅ No broken or invalid links

• ✅ Consistent formatting throughout

Content Validation

• ✅ Clear, unambiguous language

• ✅ Comprehensive coverage of essential files

• ✅ Logical organization of content

• ✅ Appropriate file descriptions

• ✅ Serves as effective LLM navigation tool

Specification Compliance

• ✅ Follows https://llmstxt.org/ format exactly

• ✅ Uses required markdown structure

• ✅ Implements optional sections appropriately

• ✅ File located at repository root (/llms.txt)

Example Structure Template

Success Criteria

The created llms.txt file should:

• Enable LLMs to quickly understand the repository's purpose

• Provide clear navigation to essential documentation

• Follow the official llms.txt specification exactly

• Be comprehensive yet concise

• Serve both human and machine readers effectively

• Include all critical files for project understanding
