tu

tu is a token and cost tracker for AI coding sessions — it tells you what Claude Code, Codex, and OpenCode are actually costing you, across every tool and every machine you work on. It syncs usage between machines and has a live watch mode for keeping the running total in a side pane while you work. If you’re spending real money on coding agents, tu is how you see where it goes.

Install

curl -fsSL https://shll.ai/install | sh -s -- tu

Installs shll + tu via Homebrew — or install the whole toolkit.

How it fits

tu is the cost overlay on the whole loop: run it alongside a fab-kit pipeline to watch what a change costs end-to-end, or keep it in view next to the run-kit dashboard while a fan-out of agents runs.
