@miya0001 :

makepot is verb, but other commands on wp-cli are noun. Is it ok?

We should discuss the best name for this command, as wp makepot is less than ideal.

Options so far:
wp i18n ...
wp translations ...
wp pot make

@swissspidy :

I'd prefer wp i18n, e.g. wp i18n makepot or wp i18n addtextdomain
