ShellOpUtility
by Frqme
ShellOpUtility is a Fabric toolkit for players who want a terminal, scans and waypoints inside the game, and it runs on client and server.
What it does
The core of ShellOpUtility is an in-game terminal with a book-style manual. The terminal keeps a command history, completes names with the Tab key and prints clickable outputs. The manual, opened with a right-click, lists categories and pages with tooltips, and each entry can open a Quick Run form that fills in the arguments for a command with a single click. Smart scans cover nearby entities, containers, spawners, ores, portals, redstone, beehives and block-entity density within a chosen radius. Results are summarized in chat with sample coordinates and clickable teleport suggestions, and scan progress is shown while the work runs in the background.
A watcher can notify the player when others enter a radius, and an optional sound signals the alert. An overlay HUD marks players, hostiles and waypoints, and it can be switched on or off. Waypoints are added, moved, deleted and listed from the terminal, and they last for the session. Coordinates can be pinged to chat as clickable text, converted between chunk, region, dimension and time formats, and a vein-follow tool tracks a connected ore vein from the block under the crosshair.
Installation uses Fabric. The mod is published for 1.21.4 and 1.21.5, with the 1.0 file for 1.21.5 as the latest build. Installation covers the server and each player's game. Scans only inspect data the client already receives, so the added load on the server is small. The code is released under All rights reserved and is not open source.
