# Update LLMs.txt File

Update the existing `llms.txt` file in the root of the repository to reflect changes in documentation, specifications, or repository structure. 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

Update the existing `llms.txt` file to maintain accuracy and compliance with the llms.txt specification while reflecting current repository structure and content. The file must remain optimized for LLM consumption while staying human-readable.

## Analysis and Planning Phase

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

### Step 1: Review Current File and Specification
- Read the existing `llms.txt` file to understand current structure
- Review the official specification at https://llmstxt.org/ to ensure continued compliance
- Identify areas that may need updates based on repository changes

### Step 2: Repository Structure Analysis
- Examine the current repository structure using appropriate tools
- Compare current structure with what's documented in existing `llms.txt`
- Identify new directories, files, or documentation that should be included
- Note any removed or relocated files that need to be updated

### Step 3: Content Discovery and Change Detection
- Identify new README files and their locations
- Find new documentation files (`.md` files in `/docs/`, `/spec/`, etc.)
- Locate new specification files and their purposes
- Discover new configuration files and their relevance
- Find new example files and code samples
- Identify any changes to existing documentation structure

### Step 4: Create Update Plan
Based on your analysis, create a structured plan that includes:
- Changes needed to maintain accuracy
- New files to be added to the llms.txt
- Outdated references to be removed or updated
- Organizational improvements to maintain clarity

## Implementation Requirements

### Format Compliance
The updated `llms.txt` file must maintain this exact structure per the specification:

1. **H1 Header**: Single line with repository/project name (required)
2. **Blockquote Summary**: Brief description in blockquote format (optional but recommended)
3. **Additional Details**: Zero or more markdown sections without headings for context
4. **File List Sections**: Zero or more H2 sections containing markdown lists of links

### Content Requirements

#### Required Elements
- **Project Name**: Clear, descriptive title as H1
- **Summary**: Concise blockquote explaining the repository's purpose
- **Key Files**: Essential files organized by category (H2 sections)

#### File Link Format
Each file link must follow: `[descriptive-name](relative-url): optional description`

#### Section Organization
Organize files into logical H2 sections such as:
- **Documentation**: Core documentation files
- **Specifications**: Technical specifications and requirements
- **Examples**: Sample code and usage examples
- **Configuration**: Setup and configuration files
- **Optional**: Secondary files (special meaning - can be skipped for shorter context)

### Content Guidelines

#### Language and Style
- Use concise, clear, unambiguous language
- Avoid jargon without explanation
- Write for both human and LLM readers
- Be specific and informative in descriptions

#### File Selection Criteria
Include files that:
- Explain the repository's purpose and scope
- Provide essential technical documentation
- Show usage examples and patterns
- Define interfaces and specifications
- Contain configuration and setup instructions

Exclude files that:
- Are purely implementation details
- Contain redundant information
- Are build artifacts or generated content
- Are not relevant to understanding the project

## Execution Steps

### Step 1: Current State Analysis
1. Read the existing `llms.txt` file thoroughly
2. Examine the current repository structure completely
3. Compare existing file references with actual repository content
4. Identify outdated, missing, or incorrect references
5. Note any structural issues with the current file

### Step 2: Content Planning
1. Determine if the primary purpose statement needs updates
2. Review and update the summary blockquote if needed
3. Plan additions for new files and directories
4. Plan removals for outdated or moved content
5. Reorganize sections if needed for better clarity

### Step 3: File Updates
1. Update the existing `llms.txt` file in the repository root
2. Maintain compliance with the exact format specification
3. Add new file references with appropriate descriptions
4. Remove or update outdated references
5. Ensure all links are valid relative paths

### Step 4: Validation
1. Verify continued compliance with https://llmstxt.org/ specification
2. Check that all links are valid and accessible
3. Ensure the file still serves as an effective LLM navigation tool
4. Confirm the file remains 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`)

## Update Strategy

### Addition Process
When adding new content:
1. Identify the appropriate section for new files
2. Create clear, descriptive names for links
3. Write concise but informative descriptions
4. Maintain alphabetical or logical ordering within sections
5. Consider if new sections are needed for new content types

### Removal Process
When removing outdated content:
1. Verify files are actually removed or relocated
2. Check if relocated files should be updated rather than removed
3. Remove entire sections if they become empty
4. Update cross-references if needed

### Reorganization Process
When restructuring content:
1. Maintain logical flow from general to specific
2. Keep essential documentation in primary sections
3. Move secondary content to "Optional" section if appropriate
4. Ensure new organization improves LLM navigation

Example structure for `llms.txt`:

```txt
# [Repository Name]

> [Concise description of the repository's purpose and scope]

[Optional additional context paragraphs without headings]
