Pawn tells you what's an upgrade but won't equip it. Zygor's Gear Advisor auto-equips, but it's bundled inside a guide suite. VocGear does the one job: when a Pawn-flagged upgrade lands in your bags, it equips it out of combat and prints a chat line. One equip per scan; the next bag update handles the rest, so valuations stay correct as gear changes. Rings and trinkets are announced, never auto-equipped: with two slots, a blind equip can replace the better one. Slash commands: /vg toggles the addon, /vg announce toggles chat messages. Requires the Pawn addon (it does the scoring, VocGear just equips).
Part of the Voc family: tiny addons that do one job.
