Command-line tool to customize Claude Code UI (themes, thinking verbs, input box style, user message display, sign-in ASCII art), fix bugs (frozen spinner), and add features (CLAUDE_CODE_CONTEXT_LIMIT).

📐 Fast and lightweight token estimation for any LLM without requiring a full tokenizer

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.
