I found the answer for the "how is it possible that t3code saves tokens" question
the biggest savings come from a smaller fixed prompt. every request to the model re-sends the same block: Claude Code's instructions plus a description of every tool it can use. theo measured this block at about 26% smaller in t3code than in the Claude Code TUI. since it's re-sent on every API call, the gap adds up to millions of tokens over hundreds of calls.
it's smaller because t3code runs Claude Code headless (in the background without its own terminal screen), and in that mode Claude Code leaves out some tools by default, such as the Artifact tool. fewer tools means fewer tool descriptions in that block.

“I’m not using T3 Code because it wastes tokens”
Bad news for the haters 🫡
2026年下期の私の開発環境をまとめました。
指示は手元PCかスマホから出して、実装はぜんぶ常駐の Worker PC に任せています。t3code を使えば Claude Code・Codex・Cursor をサブスクのまま使い分けられて、かなり快適です👇

Announcing tsc-rs (aka ts-rust), my complete rewrite of the Typescript compiler, type checker, and LSP, all in Rust.
This is a project I've had agents working on for 5 months now. I burned ~$400k of Codex tokens and got nowhere. Burned ~$20k of Opus and got there in 2 weeks.
I have not read a single line of the code.
tsc-rs is an open source drop-in replacement for tsc, and it's available now.
