README

jev-router

Automatic per-turn model routing for Claude Code and OpenAI Codex. Jev sends simple work to the fast tier and difficult work to the strong tier, while preserving each CLI's native interface, tools, sessions, permissions, and authentication.

Command	Interface	Authentication	Routing decision
`jev-claude`	Claude Code	Existing `claude login`	Status line
`jev-codex`	OpenAI Codex	Existing `codex login`	Commentary line

Both commands launch the real upstream CLI. Jev only chooses the model for a fresh user turn.

Quick start

Requires Node.js 20.12+ and at least one supported CLI: [Claude Code](https://code.claude.com/docs/en/setup) or [OpenAI Codex](https://developers.openai.com/codex/cli).

1. npm package

npm install -g jev-router
echo "JEV_API_KEY=..." > ~/.jev-router.env

2. Local repository

git clone https://github.com/gargpratyush/jev-router.git
cd jev-router
npm install
npm link
echo "JEV_API_KEY=..." > ~/.jev-router.env

On Windows PowerShell:

Set-Content "$HOME\.jev-router.env" "JEV_API_KEY=..."

Get a key from [TypeSafe](https://docs.typesafe.ai). Then launch either interface from any repository:

jev-claude
jev-codex

No Anthropic or OpenAI API key is required when the corresponding CLI is already logged in with a subscription. Every CLI argument is forwarded:

jev-claude --resume
jev-claude -p "fix the failing test"
jev-codex resume --last
jev-codex exec "fix the failing test"

For a local checkout, `npm link` installs both commands. Without it, run `node bin/jev-claude.mjs` or `node bin/jev-codex.mjs`.

`jev-claude` launches Claude Code with **Jev Router** selected in `/model`. Selecting another model pauses routing; selecting **Jev Router** resumes i
