Claimo v1.4

Claimo - Voucher/code redemption plugin for PaperMC 1.21.1-26.2.

Players redeem codes with a configurable command; each code runs one or more server commands and can gate redemption behind requirements (blocks mined, playtime, …). 

Creating codes in-game (1.21.7+)

/<command> create opens a multi-page Dialog wizard. Page 1 is the code itself (name, command with %player% support, run-as-console, hide-from-list, and an optional usage limit — max uses with a per-player / shared toggle). The following page(s) list every registered requirement type — built-in and any added by addons — each with an on/off toggle and its configurable fields; toggle the ones you want and set their values. Requirements are paginated, so if there are too many for one page the wizard adds another. Use « Back / Next » to move between pages and Create on the last page to write vouchers/<name>.yml and reload. For advanced options (multiple commands, whitelist/blacklist) edit the generated file.

The Dialog API only exists on Paper 1.21.7+. On 1.21.1–1.21.6 the creator is automatically disabled (the plugin still loads and everything else works); /<command> create reports that it's unavailable and you author voucher files manually. The jar is built against the 1.21.8 API but keeps api-version: 1.21, and all Dialog code is isolated so it's never loaded on older servers.
