⚙️ Configuration

Admin Configuration

Navigate to Stores > Configuration > BC Marketplace > LLMs Feeder to configure the module:

General Settings

• Enable Module: Enable/disable the module for the current scope
• Store for LLMs Generation: Select which store's content should be used for generating the llms.txt file (default scope only)
• Site Description: Provide a general description of your company/site
• LLM Instruction: Define essential details such as important notes, brand voice, tone, target audience, and specific directives to guide LLM
• Content Types: Multiselect field containing "CMS Page", "Product", "Category" - if all are selected, then CMS pages, products, and categories are included in llms.txt, else only selected types are included
• Custom File Directives: Optional textarea field to add custom content to the end of the llms.txt file (disclaimers, links to terms of service, or other final instructions for the LLM)
• Company Info Pages: Manually specify CMS page identifiers for company information (only used when sitemap is not available)

Generation Settings

• Frequency: Choose how often the file should be generated
  • Daily
  • Weekly
  • Monthly
• Generation Time: Set the specific time for generation (24-hour format, e.g., 02:00)
• File Status: View the current status of the generated file for the selected store

Store Selection Feature

The module includes a Store Selection configuration that allows you to specify which store's content should be used for LLMs generation:

Key Features

• Default Scope Only: The store selection is only available at the default configuration scope
• Single Store Focus: Generate content for one specific store only
• File Status Integration: The file status display shows information for the selected store
• URL Generation: The "View File" link points to the selected store's content
• Custom Router Integration: The custom router serves content from the selected store

How It Works

1. Configuration: Select your desired store from the "Store for LLMs Generation" dropdown
2. Generation: When you generate LLMs content, only the selected store's data is processed
3. File Creation: A single llms.txt file is created
4. Access: Access the content via https://yourdomain.com/llms.txt (serves the selected store's content)

Benefits

• Focused Content: Generate content for your primary store
• Performance: Fast generation and optimized file sizes
• Simplicity: Single file to manage
• Targeted Training: Perfect for LLM training focused on your store's content

Sitemap Integration

The module automatically detects if a sitemap exists at <base_url>/sitemap.xml. When a sitemap is present:

• Automatic Company Info: Company links are automatically populated from the sitemap
• Field Disabling: The "Company Info Pages" field is automatically disabled
• Fallback: If no sitemap exists, manual CMS page selection is used

🚀 Usage

Manual Generation

Generate the LLMs file manually using the console command:

Automatic Generation

The module automatically generates the file based on your configured schedule. The cron job is automatically managed and updated when you change the frequency or time settings.

🎯 Content Generation

The module generates LLMs content for your selected store using a simple and efficient process.

Admin Interface Generation

When using the "Generate Now" button in the admin interface:

1. Location: Navigate to: Stores > Configuration > BC Marketplace > LLMs Feeder
2. Action: Click "Generate Now" button
3. Result: Generates LLMs content for the selected store only

Console Command Generation

The console command provides simple generation:

Generation Process

The module uses the following logic to determine which store to process:

1. Store Selection Config: Uses the store selected in the configuration
2. Fallback: If no store is selected, uses the default store

Benefits of Single Store Generation

• Performance: Fast generation with optimized processing
• Resource Efficiency: Lower memory usage and faster execution
• Simplicity: Single file to manage and maintain
• Focused Content: Perfect for targeted LLM training
• Incremental Updates: Update content incrementally across stores

File Locations

The module generates files in the following locations:

Store-Specific Content Files

LLMs Renderer File

Accessing LLMs Content

You can access LLMs content via your web server at:

The renderer will automatically serve the appropriate store-specific content based on the request context. See Custom Router Implementation for details.

📄 File Output

The module generates two types of files:

1. Store-Specific LLMs Files

Store-specific content is saved to:

For example:

2. LLMs Renderer File

A PHP renderer file is installed at:

This file automatically serves the appropriate store-specific content based on the request context.

Content Structure

Each store-specific llms.txt file follows this exact structure:

Content Rules

• Company Section: Uses blockquote format for better readability
• Categories: Include meta descriptions when available
• Products: Listed by product name (not short description) with meta descriptions
• CMS Pages: Simple list format without subheadings
• No Variations: Product variations are excluded from the output

Access Methods

Once configured, you can access LLMs content through various methods:

1. Default Store Access

2. Store-Specific Access via Subdomain

3. Store-Specific Access via Custom Header

Security Considerations

• The renderer file includes security checks to prevent direct access
• Content is served with appropriate cache headers (1 hour cache)
• 404 errors are returned for non-existent store codes
• The file falls back to the default store if the requested store doesn't exist

🌐 Multi-Store Support (Not supported in Community Edition)

The module fully supports multi-store Magento installations with advanced scope-based generation capabilities:

Store-Specific Processing

• Individual Processing: Each store is processed independently
• Scope Checking: Only processes stores where the module is enabled
• Separate Files: Each store gets its own LLMs file in pub/llms/{store_code}/llms.txt
• Dynamic Rendering: The main pub/llms.txt file dynamically serves the appropriate store content
• Store-Specific URLs: Maintains proper store-specific URLs for all content
• Fallback Support: Falls back to default store if requested store doesn't exist
• Selective Generation: Generate content for specific stores or websites based on admin scope

Configuration

• Store-Specific Settings: Each store can have different module settings
• Scope Inheritance: Website and store-level configurations inherit from default
• Independent Control: Enable/disable the module per store as needed
• Scope-Aware Generation: Generate button automatically adapts to current admin scope

Scope-Based Generation Features

Admin Interface

• Automatic Scope Detection: The "Generate Now" button automatically detects the current admin scope
• Store-Level Generation: Generate content for a single store when in store scope
• Website-Level Generation: Generate content for all stores under a website when in website scope
• Global Generation: Generate content for all stores when in default scope

Console Commands

• Error Handling: Gracefully handles invalid store IDs with appropriate logging
• Backward Compatibility: Default behavior processes all stores when no parameters provided

File Status Display

The module provides file status checking for the selected store:

File Status

• Checks: If llms.txt exists for the selected store (pub/llms.txt)
• If file exists: Shows "✓ File exists for selected store: [Store Name]" + clickable "View File" link
• If file doesn't exist: Shows "✗ File has not been generated yet for selected store: [Store Name]"

⏰ Cron Jobs

Automatic Management

The module automatically manages cron job configuration:

• Dynamic Scheduling: Cron expression updates automatically when frequency/time changes
• Configuration Persistence: Settings are saved to the database and applied immediately
• Cache Management: Configuration cache is cleared to ensure changes take effect

Manual Cron Setup

If you prefer manual cron management, add this to your crontab:

🚀 Custom Router Implementation

The module includes a custom router system that eliminates the need for web server configuration (Apache/Nginx) while serving the selected store's content.

How It Works

1. Request Interception: The custom router intercepts all requests to /llms.txt
2. Content Serving: Serves the content from the selected store configuration
3. Direct Access: Provides direct access to the selected store's LLMs content
4. Automatic Fallback: Falls back to default store if selected store doesn't exist

Benefits

• Zero Configuration: Works out of the box without Apache/Nginx changes
• Simple Access: Direct access to your selected store's content
• Performance Optimized: Includes proper caching headers and error handling
• Seamless Integration: Fully integrated with Magento's routing system

Access Methods
