ElfUtils Mod
by DEV-snowelf
ElfUtils is a Fabric and Forge client mod that bundles small quality-of-life tools, including a pre-configured chat message helper and an in-game calculator.
What it does
Players who run an AFK farm or repeat the same chat lines can set up preset messages that are sent through short commands. A separate helper evaluates simple math typed in chat, so a quick sum can be worked out without leaving the game. The mod is built to cut routine manual steps and does not change core gameplay mechanics, and each helper can be turned on or off in its settings.
Only the client needs ElfUtils, so players install it while servers do not. It is published for Fabric and Forge across 1.16.5 and 1.21.1, with the 3000.1 file for 1.21.1 and the 3000.3 file for 1.16.5 both in the beta channel. The code is released under the MIT License and is open source, with the source and issue tracker available on GitHub.
Key features
Pre-configured chat messages
Saved chat messages are sent with simple commands, which helps with repetitive typing during long sessions.
In-game calculator
Simple math entered in chat is solved in place, so the result appears without opening another program.
Configurable helpers
Each helper can be adjusted or disabled, so players keep only the tools they use.
Lightweight design
The helpers are small and mostly idle, which keeps their effect on frame rate low according to the author.

Use cases
AFK farm upkeep
Preset messages let a player keep a farm or a long idle session running while repeating the same chat lines on a timer.
Quick arithmetic while building
A player working out block counts, coordinates or resource totals can solve the sum in chat and keep playing.
Who it’s for: Players who want small convenience tools in their own client, including those who run AFK farms or type the same chat messages often. Server owners do not need to install anything for it.
