I asked that way because I saw people here on ENworld talking about "hiding as a Minor action." So, yeas, I agree that you need to be doing something.
The next question you'll need to decide on is
does fluff rule over crunch? You have to decide that, because in RAW there is no guide as to which actions can be performed stealthily and which can't. My view is that I don't mind my shy n00b having as much fun as my Drama-major vet; so bottom line I say yes or no based on their having cover or concealment and spending an action. Of course, like anyone I'll rule out nonsense
That's why I put in my posted rulings that you can stealth with a minor action. That doesn't mean I envision anyone saying 'I
stretch up on tippy-toe humming the bee song... and hide' unless they're Tinkerbell.
And, "Move 0" sounds utterly bogus to me, no offense. That's not rules-kosher by any stretch.
A move of 0 has been 'clarified' by WotC as permitted. It's possibly needed in conjunction with some powers, or perhaps it's just a pro forma.
The problem is determining what "Stealth works with it" means. A common interpretation is that using Stealth as part of an action doesn't necessarily conceal you, but rather conceals the action. You draw your dager stealthily - does that mean that suddenly you can't be seen? Or that nobody noticed you draw the dagger?
You identify here one of the pivotal decisions DMs have to make about stealth. Line one of the Stealth rules block on PHB188 reads '
Part of whatever action you are trying to perform stealthily'. Doing a bit of forensic reading, the positioning of that line as the opening article of the mechanics block marks it out for special attention. It should key your intentional stance toward everything that follows.
The only
mechanical consequence of successful stealth use is under the Success caption.
'You avoid notice, unheard and hidden from view. If you later attack or shout, you're no longer hidden.' Here's where the issue is. Line one should have read 'Your action...' instead of 'You', and line two should not contain 'later'. Later cannot be contained to 'later, during this action', but includes 'later, after this action'.
Taken together with the white section preamble, many people adduce the wording in support of a lasting hidden condition. I've offered two takes on it

and
only with the action here

Which is right? You'll have to decide. Meanwhile I'm penning an open letter to WotC to urge them to pick one.
