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
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.
| Agent | Files it reads from the repository |
|---|---|
| Aider | files listed under read: in .aider.conf.yml (CONVENTIONS.md only when listed or passed with --read) |
| Amp | AGENTS.md (or AGENT.md / CLAUDE.md), nested AGENTS.md, @-mentioned files, .agents/skills, .claude/skills |
| Augment Code | AGENTS.md and CLAUDE.md at every level, .augment-guidelines, .augment/rules/ (by type), skills in .augment, .claude, .agents |
| Claude Code | CLAUDE.md, CLAUDE.local.md, .claude/rules, skills, commands, subagents, AGENTS.md when there is no CLAUDE.md |

| Factory Droid | AGENTS.md / CLAUDE.md (also in .factory, .agents, .agent), DESIGN.md, .factory/skills, .agents/skills, .factory/droids |
| Gemini CLI | GEMINI.md, skills in .agents and .gemini |
| GitHub Copilot | .github/copilot-instructions.md, .github/instructions/, AGENTS.md, CLAUDE.md, .claude/rules, skills in .github, .claude, .agents (VS Code Local harness defaults) |

| Google Jules | root AGENTS.md |

| Kiro | .kiro/steering/, AGENTS.md (nested ones too, every turn), .kiro/skills |
| OpenAI Codex | AGENTS.md, AGENTS.override.md, .agents/skills |
| OpenCode | AGENTS.md, or CLAUDE.md when there is none; skills in .opencode, .claude, .agents |
| Roo Code | .roo/rules/, .roo/rules-{mode}/, .roorules, AGENTS.md, skills in .roo, .agents |
| TRAE | .trae/rules/ (alwaysApply, globs, description; three folder levels), .trae/skills |
| Warp | WARP.md, else AGENTS.md; skills in .agents, .warp, .claude and seven other folders |
| Windsurf Cascade | .devin/rules/, .windsurf/rules/, .windsurfrules, AGENTS.md, skills (legacy agent; new conversations use Devin Local) |

Where an agent reads the same skill name from two folders, it is counted once, in the order the agent documents (or an assumed order, noted for that agent).
Agents that load exactly the same files share one row in the report (files loaded only as a /command, which cost nothing per turn, do not split a row):

Advice (savings are estimates in o200k tokens per turn) HIGH duplicate CLAUDE.md, AGENTS.md [saves ~48 tokens/turn] 3 identical lines are loaded twice every turn by cursor, copilot, factory-droid, augment, devin. Keep them in one file. HIGH contradiction AGENTS.md, CLAUDE.md [saves ~11 tokens/turn] Conflicting package manager: "Always use npm for installs and scripts in this repository." (AGENTS.md:3) vs "Always use pnpm for installs and scripts in this repository." (CLAUDE.md:5). (Removing the outdated line.) MEDIUM scopable-section CLAUDE.md:12 [saves ~128 tokens/turn] Section "API package" is mostly about packages/api/. Move it to packages/api/AGENTS.md (or CLAUDE.md), a path-scoped rule, or an instructions file ...
(Excerpt of the output for test/fixtures/mixed with --models gpt-6.1-sol.)
| Model family | How tokens are counted | Label |
|---|---|---|
| OpenAI GPT-5.x, gpt-oss | Offline with o200k_base (the encoding OpenAI's tiktoken maps them to) | exact |
| OpenAI GPT-6.x | Offline with o200k_base; OpenAI has not published a newer encoding | estimate |
| Claude | Only Anthropic's count_tokens API, with your key and --claude-api | API count |
| Gemini | Only Google's countTokens API, with your key and --gemini-api | API count |
Claude's tokenizer is not public, and Anthropic's docs note that newer Claude models produce noticeably more tokens than older ones for the same text. turntax never shows an OpenAI count as a Claude or Gemini number: without a key those rows say "needs API key". The o200k column is a labelled reference count for every file.
Cost per N turns = tokens per turn × N × input price. The "cached" column assumes every turn reads the context from the prompt cache. Prices come from a dated table with a source link per model (turntax --list-models); pass --prices my-prices.json to use your own.
See docs/how-it-counts.md for the loading rules per agent and their sources.
All checks are deterministic. Each one shows an estimated saving in o200k tokens per turn.
applyTo)..md files in .cursor/rules or Windsurf rules without a trigger.npm run scripts that no longer exist.--english CLAUDE.md=CLAUDE.en.md) or, if you opt in, a Claude translation (--translate).npx turntax --fix # print a diff of the safe fixes; nothing is changed
npx turntax --fix --write # apply them
--fix handles four kinds of advice:
CLAUDE.md that repeats at least 80% of the lines of the AGENTS.md next to it, at least 3 of them full sentences, and every file it imports, keeps only its own lines and imports the rest with @AGENTS.md, as Claude Code's docs suggest; agents that read both stop paying for the copy, and the summary says how much any agent now reads on top.packages/api/CLAUDE.md), a nested AGENTS.md, or a Claude Code rule with paths:. The folder the section is about must already exist, and sections with @imports or relative links stay put. A section moves together with its subsections.--section-tokens, 600 by default, whose heading names a release, deploy, setup or similar procedure, or that is mostly numbered steps; each subsection must pass too) into a new skill, .claude/skills/ /SKILL.md for Claude Code or .agents/skills/ /SKILL.md for Codex, and leaves the heading with a one-line pointer. Only the skill's name and description load every turn. Many agents now read one or both folders, but not all of them do (Zed reads only .agents/skills, for example), so by default this fix is often refused; --tools limits the check to the agents you use..md files in .cursor/rules to .mdc.Before a fix is kept, the files are classified again with the change applied: every agent must still read every line it read before, including files reached through @imports, and as often as before. The exceptions are moved text: a section moved into a folder may load only when the agent works there, and a procedure moved into a skill only when the skill is used. Otherwise the fix is skipped and the reason is printed. A moved section can reach agents that did not read it before (a nested AGENTS.md is read by more agents than a CLAUDE.md); the summary names them. By default that check covers every supported agent, so a section of AGENTS.md usually stays where it is, because some agents read only the root file. --tools codex,claude-code limits the check
