JevOnly

Hand the browser work off: an MCP server where a decision model drives the page for your agent, so a flow costs one tool call instead of a turn per click. Ref-based element tables, code-checked assertions, zero-model macro replay. Speaks CDP to your Chrome.

Let Jev, TypeSafe's ~100ms decision model, drive your browser. A plug-and-play skill for Claude Code and Codex.

Drives a real browser with Jev making every decision and Vercel's agent-browser performing every action, with a benchmark.

Checks whether a coding agent completion claim is actually true: deterministic evidence gathered in code, one batched Jev assessment, and a pure policy. DSH plugin.

Software Factory Foreman: an agent supervisor that uses Jev decisions to keep coding agents on task.

Vercel Labs terminal CLI that can run Jev as the evaluation model for its evaluate command.

Convert legacy chat completion API request to Typesafe jev API

A context compactor that can only score, never write — so an agent's memory can't hold a fact the transcript never contained. Working demo, runs offline.

Type-safe one-decision-per-token decoding engine for autoregressive LLMs, inspired by Jev.
