How it works
This stat adds levels to every skill in one skill tab of one class, e.g. "+7 to Elemental Skills (Druid Only)" on Earth Shifter. Each class has three tabs, and the bonus covers every skill in the tab at once.
The levels add to your own points and to every other +skill bonus, and stack with All Skills and Class Skill Levels. Like all item skill levels, they do not count toward synergies.
The bonus works only for the class named in the tooltip; for anyone else it does nothing.
Grand charms with +1 to a skill tab, called skillers, are the common way to stack it. Astreon's Iron Ward and Thunderstroke are other examples. See also Single Skill Levels.
From the tables
what itemstatcost.txt, properties.txt and the rule constants say about it- On an item the game prints it as +N to a skill tab (itemstatcost.txt descfunc 14). (game table)
- One item can store from 0 to 7 of it (Save Bits 3, Save Add 0); that bounds one item, not your total. (game table)
- Set by 2 item properties:
skilltab,war-tab-rand(properties.txt). (game table)
game table: a column of itemstatcost.txt, properties.txt, difficultylevels.txt or charstats.txt (build 3.3.93847). derived: the rule page this stat belongs to. published rule: an engine constant no table holds, from data/game/rules.json with its source.

Source: itemstatcost.txt (item_addskill_tab) and properties.txt over the property codes of the game's item tables, the runeword lines and skills.txt (build 3.3.93847). Magic affixes are the ones that can spawn; a runeword's line includes what its runes add in that slot. “LoD 1.14d” is the value in classic Diablo II's last patch where it differs (uniques, set items, runewords' own bonuses, runes and gems; from blizzhackers/d2data); a D2R chip marks what 1.14d did not have. “Strongest” ranks items by the top of their roll range. · Report incorrect data
