It is easy to send commands to Drafts. This is done using actions defined in Drafts' URL scheme. Using a custom action, we can send arbitrary JavaScript to be executed in Drafts.

The more difficult thing is how to get a response back from Drafts to the CLI. Drafts' URL scheme offers a x-success parameter which can be used to call a separate URL with the result of an action. The problem is that the drafts CLI process can't catch this call directly.

My solution to this problem was to make a separate macOS app (Drafts CLI Helper) whose only purpose is to catch x-success calls from Drafts, and forward them via Unix socket to the appropriate drafts CLI process. The resulting system is illustrated below.
