A token counter answers two questions before you send a request: does the prompt fit, and what will it cost. How counting works and where estimates go wrong.

Inspect Claude Code / Codex CLI conversations locally. Token breakdown, per-turn costs, compaction timeline, framework-overhead audit. Python + tiktoken.

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.
