Saves tokens by shunting I/O-heavy work to a cheap worker model. Hooks block large file reads and redirect to bulk-read/code-write, which run one headless turn on whichever CLI you have: claude, gemini or codex.

## What shunt does, in the publisher's words

> This is a port of Spotify's shunt plugin. > The idea, the hook design, the two delegation scripts and the worker instructions are > Spotify's, from portal-ai-plugins and the > engineering post Portal by Spotify cut my Claude Code token usage by 90%. > Their worker runs on AiKA in Portal by Spotify, a paid enterprise product, so you need a > Portal tenant to use it. > > What this fork changes: the worker is a CLI you already sign into, and the gate works in > Claude Code, Codex CLI and Gemini CLI instead of only Claude Code. Most files here are > still theirs, NOTICE lists the provenance file by file. Apache-2.0, same as upstream.

Your coding agent spends most of its context on I/O, not thinking. Reading one 1,400-line service file costs ~15,000 tokens of context that you then pay for on every subsequent turn of the conversation.
