As someone who low-key detests the endless grind of lower levels, I was delighted to discover You Are Not A Novice - Higher Level Start, a mod that lets you play an experienced character from the very beginning, by picking a class that determines what skills you've already mastered. However, I soon noticed an inconsistency when using it alongside Hand to Hand: the latter replaces the Pickpocket tree with Security (a combination of Pickpocket and Lockpicking) and swaps Lockpicking for its new eponymous skill, but YANAN message boxes still showed the old names. Hence the patch, which works as a plugin replacer. Now YANAN's stealth classes are described as follows:

Thief
A well-rounded specialist of stealth.
Major skills: Security, Hand-to-Hand, Sneak
Minor skills: Light Armor, Speech, Archery

Assassin
A professional killer who relies on stealth to approach their victims unseen.
Major skills: Sneak, Archery, One-handed
Minor skills: Alchemy, Light Armor, Security

Bard
A loremaster and storyteller who relies on sword, shield and spell to preserve themselves from perils - and is not unfamiliar with drunken bar brawls.
Major skills: Light Armor, Speech, One-handed
Minor skills: Hand-to-Hand, Block, Illusion
Spells: Courage (always), Fear (expert and above)

Mechanically, nothing was changed, since the skills are swapped out automatically and the only issue was ending up with some inconsistent message.
If you don't like the resulting combos, or would like to build your own anyway, it's all quite easy to customise in xedit (while "Message" is where I went to fix the description, if you want to edit the actual skills you have to go under FormID List and look for the one you want to tweak; for instance, if you want to tweak the Thief class you must look for yananListSkillStealthThief, then on the right side you can select whatever you like better).
