Tupenter

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): TupenterModClient did not start: java.lang.NoClassDefFoundError: net/minecraft/network/chat/ClickEvent.

In the author's words

Resend chat and commands with a keybind and then even script them: chain with &&, inline math, variables, loops, conditionals, and your own commands with real autocomplete. All client-side, sending plain vanilla commands.

Scan

Scanned on 4 November 2026 against Kiln 0.2.0, file tupenter-fabric-26.3.X-v1.4.1.jar. The scan reads the mod's classes; it does not run them.
