9 practical Jev API recipes: browser agent flies through Google Flights in 7 seconds

A community roundup lists nine ready-made projects for the newly hot Jev API:

jev-ultrafast (browser-use, 12.3k stars): a fast browser agent where Jev only picks the operation and target element each step; a small LLM writes text only for TYPETEXT. Dynamic indexed action space; measured 7.1 seconds for a Zürich→London Google Flights search.
fast-jev-compaction: context compaction for Claude Code — Jev judges which tool outputs to keep, deleting useless ones without rewriting.
-render (Vercel Labs): generative UI where Jev selects components, props, and layout instead of writing JSON token by token.
typesafe-mcp: plug Jev into Claude Code, Claude Desktop, Codex, and Pi for Choice/Score/Noul tasks.
jev-mcp: an agent judgment toolbox for fact-checking, moderation, semantic ranking, classification, extraction.
SemDecide: Jev as a CLI for classify/score/filter in shell pipelines, crawlers, and CI.
jev-codex-router: Jev rates coding-task difficulty to pick model tier, reasoning depth, and speed mode.
Winnow: garbage collection for Claude Code context, filtering irrelevant Read/Bash/Grep output.
jev-review: pre-screen code changes with Jev, routing only high-risk ones to pricier models or humans.
