URL-scheme details for Reminders application

Solution 1:

I don't know the details of URL scheme. However the scheme is x-apple-reminder not reminders It can launch reminder app at least.

However the host and path rule is not revealed yet. Reminder widget can open Reminder with specific EKReminder, So, there must be a scheme definition for it.

The scheme x-apple-reminder is undocumented, So using it should be rejected.

Solution 2:

jeeyul's answer mentions x-apple-reminder as an alternative URL scheme.

While both reminders:// and x-apple-reminder:// work on OSX to merely launch the Reminders app, it turns out that the following works only with x-apple-reminder://, which shows how to open (jump to) a specific reminder:

x-apple-reminder://{reminderId}

Example: from Terminal, open the reminder whose ID is 0BFDC528-306D-47A7-8E8F-895ACCDC6FFA:

open x-apple-reminder://0BFDC528-306D-47A7-8E8F-895ACCDC6FFA

However, doing the same for a reminder list does NOT work, so this part of my question is still unanswered - I'm still marking it as accepted for at least providing a partial solution.
