 `tokdu` (Token Disk Usage) is a terminal-based utility that helps you analyze and visualize token usage in your codebase. Similar to the classic `du` (disk usage) command, tokdu shows you how many tokens your files and directories consume, which is essential when working with Large Language Models (LLMs) that have token limits.
