Ran @typesafeai's Jev against an existing classifier eval that previously used Gemini 2.5 Flash Lite. It won both on quality (saturated the eval) and speed (6x)
Typesafe MCP
A single-binary Go MCP server exposing one evaluate tool for noul, choice, and score questions, with one-command registration for Claude Code, Claude Desktop, and Codex.

Highlights
- Exposes one MCP tool, evaluate, with noul, choice, and score question types.
- One command registers Claude Code, Claude Desktop, and Codex when each is detected.
- Retries 429 and 529 with exponential backoff, with a 60-second timeout and 16 MiB response cap.
- Ships as a single static Go binary with a checksum-verified self-update.
Watch out
Needs a TypeSafe or OpenRouter key, and OpenRouter's decisions endpoint is still alpha and may move.

A Python asyncio runtime that puts Jev in a supervision loop above Codex or OpenCode workers: it judges completion, test sufficiency, and stuck loops, then steers, retries, or stops the job.

A staged code-review workflow that uses Jev for bounded judgments over Git diffs or whole codebases, with a local dashboard. Policy and thresholds stay in code while Jev screens five risk areas.
