Creating Your Own Extension

Check out our extension-template to get started quickly.

Extensions can provide:

• Tools — callable functions for the AI (e.g., sulu-content-types, doctrine-schema)
• Resources — static context about your framework/CMS
• Prompts — pre-built prompt templates for common tasks

Quick Start

# Install an extension
composer require --dev matesofmate/example-extension

# Initialize Mate in the project
vendor/bin/mate init

# Refresh discovery artifacts if needed
vendor/bin/mate discover

# Verify it's loaded
vendor/bin/mate debug:extensions
vendor/bin/mate debug:capabilities

In current AI Mate setups, extension discovery is handled automatically after Composer install and update. For Codex, use the generated ./bin/codex wrapper.
