AI MateCAUTION

The Mate component provides a command-line assistant (vendor/bin/mate) that exposes project-aware development tools to coding agents (Claude Code, Codex, Cursor, ...) and developers. Agents run the mate commands directly, so tool schemas are read on demand via --help/tools:inspect instead of being loaded up front. This is a development tool, not intended for production use.

Install it in your project with:

composer require --dev symfony/ai-mate
vendor/bin/mate init
composer dump-autoload

Point your coding agent at the CLI (see the generated mate/AGENT_INSTRUCTIONS.md):

vendor/bin/mate tools:list                          # list available tools
vendor/bin/mate tools:inspect symfony-profiler-list # show a tool's parameters/schema
vendor/bin/mate tools:call symfony-profiler-list --limit=1
vendor/bin/mate resources:read symfony-profiler://profile/

Add --format=json to the tools:*, resources:read, debug:*, skills:list and skills:validate commands for machine-readable output.

The package ships with the symfony/ai-mate-composer-plugin, which automatically refreshes Mate extension discovery after composer install and composer update once the project has been initialized.

Installation

composer require --dev symfony/ai-mate
