# trirouter – One Prompt Router for Claude Code, Codex & Antigravity         **trirouter** runs before every prompt you send to Claude Code, OpenAI Codex or Google Antigravity – in every project, in the desktop apps and in remote sessions – and decides for that single request: * **which model** and **which reasoning effort** to use, * **how many extra agents** may work in parallel (strict token budget), * **which skill** fits – from one shared folder that all three tools read, * whether the request is **irreversible** (then the model must ask before acting), * **which language** to answer in (the language of the prompt). > Formerly **jev-router**, renamed because unrelated packages already use that name on npm and PyPI. > Internal names stay the same, so existing installs keep working: the `jev_router` Python package, > `~/.jev-router/` and the `jev-router` MCP server. It also **protects running work**: a prompt sent while an earlier one is still being processed is queued behind it and must not stop or overwrite it. Decisions come from **JEV (TypeSafe)** when you configure a TypeSafe token or an **OpenRouter key** (JEV is on OpenRouter since September 2026). Without one, a built-in local classifier with the same answer format decides – everything works out of the box. --- ## 🚀 Quick Start Requirements: Python 3.10+ and at least one of [Claude Code](https://code.claude.com/docs/en/quickstart), [Codex CLI](https://developers.openai.com/codex) or [Antigravity CLI](https://antigravity.google/docs/cli/install/). ```bash git clone https://github.com/hajdu-patrik/claude-workspace.git trirouter cd trirouter python install.py ``` The installer walks you through five steps: 1. **Detect** which of Claude Code, Codex and Antigravity are installed and logged in, and tell you how to log in to the ones that are not. 2. **JEV access** – paste a TypeSafe token or an OpenRouter key (`sk-or-…`), or press Enter to use the built-in local classifier. 3. **Hooks + MCP server** for every logged-in tool. 4. **Shared skill folder** `~/.skills` – existing skills of every tool are moved there and linked back, so each tool sees all of them; worker agents are generated for every model × effort. 5. **Optional extras** – remote access from your phone, speech-to-text. Every change is shown first, changed config files get a `.bak` copy, and re-running is safe. Preview without changing anything: `python install.py --dry-run`. | Command | Purpose | | --- | --- | | `python install.py detect` | report installed / logged-in tools | | `python install.py models --probe` | test which models your accounts may use (stored per user) | | `python install.py remote --name "My PC" [--workdir <folder>]` | remote access from other devices ([guide](docs/remote-access.md)) | | `python install.py uninstall` | remove hooks, MCP entries and remote access (skills stay) | | `python install.py skills [--apply]` | re-link skills, regenerate workers, rebuild the catalog | | `python install.py doctor` | health report | | `python install.py route [--provider claude] [--json] <text>` | routing decision for one prompt or sub-task, side-effect free ([details](#routing-decision-on-demand)) | **One-time steps after installing:** Codex runs a new hook only after you trust it (`codex` → `/hooks`). For Claude desktop *Chat/Cowork*, restart the app and add to *Settings → Profile → Personal preferences*: *"Before answering any new request, call the jev-router route_prompt tool with my message and follow its instructions."* --- ## 🧭 How It Works ``` prompt ─► hook / MCP tool ─► jev_router/core.route() ├─ is_continuation() "mehet" / "yes, do it" → keep the last decision ├─ split_pasted() pasted blocks never decide language or task ├─ lang.detect() answer language ├─ is_destructive() regex safety net (+ JEV verdict) ├─ catalog.prefilter() shared skill catalog → ≤ 8 candidates ├─ classify() JEV (TypeSafe / OpenRouter) or built-in classifier ├─ decide() routes.json: task × difficulty → tier └─ render() targets.json: tier → worker, model, effort + queue_state earlier work still running? → "finish it first" ─► "[router] … Delegate to `opus-worker-xhigh` (opus, effort xhigh). Parallelism: none. Respond in English." ``` | Surface | Mechanism | | --- | --- | | Claude Code (CLI, desktop *Code*, Remote Control) | `UserPromptSubmit`, `Stop`, `StopFailure`, `SessionEnd`, `SubagentStart` hooks | | Codex (CLI, ChatGPT app in Codex mode) | `UserPromptSubmit` + `Stop` hooks | | Antigravity (CLI, desktop app) | `PreInvocation` + `Stop` hooks (prompt read from the transcript, injected once per turn) | | Claude desktop *Chat / Cowork* (no hooks there) | MCP tool `route_prompt` | | Claude Code on the web (cloud sandbox) | project hook with `--cloud-only` | | Scripts, other agents and projects (per sub-task) | `route` command via the shim `~/.jev-router/bin/route.py` | ### Model and effort are enforced, not suggested No tool lets a hook switch the running model. trirouter therefore generates one **worker agent per (model, effort) pair** – Claude subagents `<model>-worker-<effort>` (plus `test-worker-<effort>`), Codex roles `<model>-<effort>` – and the router delegates to the right one. Antigravity agents can pin only a model tier (flash / pro), not an effort, and only as subagents: trirouter generates `gemini-flash-worker` and `gemini-pro-worker` (`~/.gemini/config/agents/`), and hard requests are delegated to the Pro one; otherwise the model choice is advisory (or enforced through `cli-bridge`). Each agent's instructions come from the template of its model's **role** in `models.json` – `fast`, `balanced`, `deep` (`jev_router/templates/agents/<role>-worker.md`), plus `test-worker` for the test tier – so a new model needs one line in `models.json`, not a new template. | Provider | Models (catalog: `jev_router/config/models.json`) | Effort levels | | --- | --- | --- | | Claude | fable, sonnet, opus – generic aliases only, never Haiku | low · medium · high · xhigh · max | | Codex | gpt-6-luna, gpt-5.6-terra, gpt-5.6-luna, gpt-reserve by default; more after `models --probe` | low … max (per model) | | Antigravity | Gemini 3.8 / 3.7 / 3.6 Flash, Gemini 3.1 Pro, Claude Sonnet/Opus 4.6, GPT-OSS 120B | part of the model name | The `ultra` effort level is never offered, stripped from any answer and has no worker. ### Follow-ups and pasted text A bare go-ahead or status check – "mehet", "igen, töröld!", "yes, do it", "hogy állunk?" – keeps the previous decision of the same session (model, effort, worker) instead of being classified on its own, where it would look trivial. At most one word beyond the go-ahead is allowed, so "ok, most írj teszteket" is routed as new work. The safety check always runs on the new prompt. Pasted blocks (`<pasted_content>`: logs, CI output, a README) are not the user's own words: they never decide the answer language or the task type. JEV still sees them as context, and the safety regex still scans them, because a pasted command can be the dangerous part. Subagent hand-backs (`<agent-message>`) are not routed at all. ### Parallel agents | Extra agents | When | | --- | --- | | **0** | default – the vast majority of requests | | **+1** | two clearly independent, substantial parts | | **+2** | three independent workstreams (e.g. backend + frontend + migration) | | **+3** | a complete new page or feature from scratch (backend + frontend + data layer) | | **+4** | very rare – the same, plus custom tooling such as a scraper | Code-level clamps: one fewer when the answer is not confident, at most +1 unless the request is hard. ### Queue protection All three tools already queue messages typed while the agent is busy. trirouter adds the missing context: the new prompt is told that earlier work in the same session is still running and must be finished first – never stopped, restarted or overwritten. If another session works in the same folder, the prompt is warned not to modify that session's files. Claude's `StopFailure` (a turn that died on an API error) and `SessionEnd` release the queue as well, and state expires automatically, so a crashed session never blocks anything. `doctor` also reports **delegation compliance**: the `SubagentStart` hook records which worker the model really started, so you can see how often it followed the router's advice. ### Shared skills `~/.skills` is the single skill folder. Claude Code and Codex see it through per-skill links (junctions on Windows, symlinks elsewhere); Antigravity through its `skills.json`. Skills that tools manage themselves (Claude desktop's synced skills, plugins, Codex built-ins) stay in place but are indexed too, so the router can hand a skill of one tool to another ("read and follow `<path>/SKILL.md`"). ### Overrides Claude `#fable #sonnet #opus #codex #antigravity` · Codex / Antigravity `#fast #main #deep` · `#norouter` / `#privat`: no routing, nothing is sent to TypeSafe (queue protection still applies). ### Routing decision on demand The hooks route each user prompt. To get a decision for a single sub-task – from a script, another agent or another project – call the `route` command. It runs the same pipeline (`core.route()`) but has no side effects: no queue state, no log. ```bash python ~/.jev-router/bin/route.py --json "add a pagination parameter to the quotes API endpoint" python install.py route [--provider claude|claude-chat|codex|antigravity] [--json] <text> # no text: stdin ``` Without `--json` it prints the `[router] …` instruction. With `--json` it prints one object: `model` (e.g. `sonnet`; `null` when the tier answers in-session), `effort`, `agent` (the worker to delegate to, or `null`), `tier`, `task`, `difficulty`, `extra_agents`, `destructive`, `skill`, `verify`, `lang`, `backend`, `text` and `note`. A `#norouter` / `#privat` prompt is not routed (`model: null`, nothing is sent to TypeSafe). Exit codes: `0` success, `2` usage error (e.g. an empty prompt), `1` unexpected error (only the exception type goes to stderr). The installer writes the shim, so callers never need to know where the repository lives. --- ## 🎙️ Speech-to-Text Dictate prompts into any app, in any language Whisper supports – offline and free. See **[docs/speech-to-text.md](docs/speech-to-text.md)** for installation, model choice by hardware and phone dictation. --- ## 📱 Remote Access Control your computer from a phone or another device under one machine name, with every tool starting its remote service at logon.

The real-traffic set (`eval/real_prompts.csv`: typos, missing accents, pasted blocks, go-aheads) has lower regression gates, because the built-in classifier is weak there and JEV is the real fix. Every set also reports tier accuracy next to the best fixed-tier baseline: routing only pays off if it beats always picking the same tier. The test suite runs on Windows, macOS and Linux in CI.
