What the publisher says

From the turntax repository's README, as published. We do not edit it. Read it on GitHub

turntax

Coding agents re-send their instruction files with every turn. turntax measures that fixed per-turn cost for a repository, for every agent that reads it, and shows where to cut it.

npx turntax

Try it in the browser, with nothing uploaded: https://torutdev.github.io/turntax/ — drop a folder or enter a public GitHub repository. Links like https://torutdev.github.io/turntax/?repo=owner/name open straight to that repository's report.

State of agent instruction files: what turntax finds in 100 popular repositories, a new edition every month with pinned commits and the script to reproduce it (scripts/state-of.mjs).

Set up the GitHub Action and a config in one command:

npx turntax init

Supported agents

Each agent's documented loading rules decide what is sent on every turn, what loads only when the agent works in a folder or touches a matching file, and what is ignored.

Agents that load exactly the same files share one row in the report:
