A few months back I published a Raycast extension that allows you to quickly search and download WordPress plugins from the official WordPress Plugin Repository. Some other notable features include :

• command to view the list of all available versions and download any of them.
• command to copy the Composer package name for installing the plugin via Composer

Side note: if you are a Mac user and haven’t heard of Raycast, I’d highly recommend checking it out. It’s essentially a more powerful “Spotlight” and is definitely a productivity booster for me.
