Raycast allows you to add extensions via script commands. Here's my fledgling collection.
This command queries my buku database and presents the results. It's a quick way to get at my bookmarks.
This command adds the active Chrome tab to my Things inbox. The task title is the webpage title, and the page URL is added to the task notes.
This command gives me a Markdown link to the current Chrome tab. It uses Applescript to get the tab's title and URL, and then pops the link on your clipboard.
