I see that it seems to support custom slash commands: https://docs.factory.ai/cli/configuration/custom-commands

Seems easy enough to add.

Droid is really nice. If I use codex to get started, renaming the prompt folder path to .factory/commands seems to work. Do there is anything else to change or I'm good to go?

I can't wait to see droid support!

Just noticed PR #650 (Droid CLI support) was labeled a 'merge-candidate' two weeks ago. Can't wait for the merge!
