D&D 2E Looking For Simpler Rogue for D&D2e/Chromatic Dungeon Campaign

[The Old Crow]

I'd maybe mix things together like:
Climb (climb walls)
Stealth (move silently, hide in shadows)
Thievery (pick pockets, open locks, remove traps)
Perception (hear noise, find traps)
Read Languages (read languages)

This consolidates them down a bit.

I really like this. That gets it down to a manageable five skills.

I'd likely also base them off ability checks rather than percentile rolls as well as let other classes attempt them but with penalties since it isn't their forte. If you want them to increase as the thief gains levels, every time they get a proficiency slot, they get a bonus slot to apply to their thief skills. Do this even if you aren't using proficiencies.

Chromatic Dungeons uses ability checks. It is otherwise a lot like the 2e Thief, but for some reason adds more skills instead of consolidating them. I really hate all clutter of trying to cram too many things onto a character sheet!

Anyway, your suggestion looks like exactly the solution I was looking for, and I am going to use it. Thanks.

I'd do something like:

Thieve's Edges:
Scuttle (climb, crawl, hanging to a ledge)
Obfuscate (move silently, hide in shadows, pickpocket)
Use Device (remove trap, set trap, lock pick, use ropes)
Cunning Senses (hear noise, find stuff, read language, Detect Illusion)

This is really good. It is a bit too different than what I am looking for, but that consolidation is impressive. It would make for a perfectly functional streamlined Thief.
