Pi TypeSafe Router
A Pi coding-agent extension that uses Jev to classify each request and route it to one of three configured models. Supports TypeSafe, Cloudflare AI Gateway, Vercel AI Gateway and OpenRouter backends, with doctor checks, shadow mode and an off-by-default setup.

About this project
Use Jev to classify requests and route them to the right model for the task. Do not enable this alongside another automatic router. Choose a real provider/model in Pi first, then run: This creates /.pi/agent/typesafe-router.json, initially off, using your selected model for all three routes. Edit the mappings, set TYPESAFEAPIKEY in the environment that launches Pi, and run /reload. Verify your configuration, then enable routing:

Highlights
- Configures via /typesafe-router setup with TypeSafe, Cloudflare, Vercel and OpenRouter example configs; starts off until enabled.
- Routes through jev-1.13.0 on TypeSafe by default; doctor tests the classifier and configured models with synthetic requests.
- Footer shows router on, shadow or off state plus the last classified route and target; offline tests make no paid API calls.
- MIT licensed and published on npm as pi-typesafe-router; asks users not to enable it alongside another automatic router.
Watch out
Requires a TypeSafe or gateway API key to classify and route. The README warns against running it alongside another automatic router.
Questions about this entry
Short answers drawn from the linked project or page.
TypeSafe (TYPESAFE_API_KEY, jev-1.13.0), Cloudflare AI Gateway (typesafe/jev), Vercel AI Gateway (typesafe-ai/jev) and OpenRouter (typesafe/jev-1.13). Each has an example config and a setup command.
No. Configuration is created with the router off; you enable it with /typesafe-router on, and doctor plus shadow mode let you verify behaviour before traffic is rerouted.
Install with `pi install npm:pi-typesafe-router`, choose a real provider/model in Pi, then run `/typesafe-router setup typesafe`. That writes ~/.pi/agent/typesafe-router.json in the off state; edit the mappings, set TYPESAFE_API_KEY, run `/reload`, then `/typesafe-router on`.
`/typesafe-router doctor` verifies the classifier and configured models with synthetic requests, without sending your conversation, using tools, or changing the selected model. The README notes these checks may incur charges, and a successful verification is restored after `/reload` when config and credentials still match.
No. The README says not to enable this alongside another automatic router. It also notes that doctor can be run without turning routing on, so you can check a configuration before any request is routed through it.
MIT, per the repository's LICENSE. The README adds that third-party models, services and dependencies keep their own terms, so routing through a provider does not change that provider's conditions.
Pi's footer always shows the active mode as `router: on`, `router: shadow` or `router: off`, with pending checks and the last classified route and target alongside it when relevant. Setting `showFooterStatus` to false in the router configuration hides the line.

MIT-licensed Python tool router for coding agents that keeps obvious calls on a fast path, asks Jev (default typesafe/jev-1.13 via OpenRouter) for genuinely ambiguous choices, and can run bounded MCTS when multi-step consequences matter. Ships a CLI, MCP server and hook integrations.

Merged PR in the Kilo Code cloud monorepo that replaces its LLM auto-routing classifier with one OpenRouter /systemone Choice request to typesafe/jev-1.13; the PR reports 0.93-0.94 route accuracy on 72 golden cases at roughly $0.00028 per call, with a 250 ms transport-error retry.

Original write-ups on what this entry is for.
The request shape barely changes across surfaces; the surrounding contract does. When to call the API directly and when a gateway, a Worker binding, or a router entry earns its extra hop.
