What’s your most underrated delegation trick?

Not looking for the obvious 'use a VA' or hire freelancers.

What’s one thing you do that makes delegation actually work for you as a founder?

Could be:

A way you brief people

A doc you reuse

A weird but effective Slack habit

I’m trying to improve how I hand things off without it bouncing back to me. I figure other solo/early-stage founders might have some battle tested tricks.
