Launches on September 17, 2026

A small Next.js app for experimenting with TypeSafe AI's Jev model (System One)

Can a System One model steer music? Jev picks the plan (enums only); code renders sheet, audio and MIDI.

Jev-augmented Playwright MCP proxy — page-state triage, prompt-injection shielding, goal-based snapshot pruning, risky-action gating. Drop-in wrapper around @playwright/mcp for any coding agent.

Typed verdicts on pull requests with TypeSafe System One (Jev): one parallel call, policy in code, usable as a GitHub Action

Non-blocking Spring Boot Starter for Spring WebFlux that implements a Semantic Circuit Breaker to detect silent HTTP 200 failures using TypeSafe Jev.

Typesafe/Jev public X demo

An experimental Snake environment where the game engine owns deterministic rules and TypeSafe AI's Jev makes the movement decision from structured state on every tick.

Typed, policy-driven decision workflows on top of TypeSafe AI Jev: confidence routing, fallbacks, evaluation, and RAG patterns for TypeScript apps.

Three.js drone simulator with a Python backend and live TypeSafe Jev navigation

An idiomatic Zig client for the TypeSafe AI API

Go SDK for TypeSafe AI API https://docs.typesafe.ai/api

Lints Jev requests before they are sent: offline checks for missing none-of-the-above options and broken state paths, then Jev itself for what structure cannot decide.

Reusable GitHub Action: agent fix loop gated by checks, an AI reviewer, and TypeSafe Jev

An experimental protocol for evidence-aware agent handoffs, bounded worker continuation, and TypeSafe/Jev-assisted review, with reproducible evaluation.

Browser Use Olympics by Almond: one prompt, five events, one clock. Plus fast loop, a ~200-line browser computer-use agent (Chrome DevTools + TypeSafe Jev).

CartShield — SMB checkout fraud disposition via TypeSafe Jev

A Next.js brick breaker whose paddle is controlled in real time by TypeSafe AI's Jev model. Built with Claude Code.

Chakravyuha — a polar ring-maze where every move is a Jev (TypeSafe System One) decision. A fun experiment: the model picks each move, the walk grades it green or red, and the history page asks whether its confidence score can be trusted. BYOK, no build step.

A CLI and GitHub Action that assesses code-change risk using deterministic rules and TypeSafe Jev, recommending checks and reviewers before merge.

Cyber-Breach: The Jev Protocol - A tactical cyberpunk arena combat game powered by TypeSafe AI Jev System One decision model
