Launching JevX — because AI shouldn’t tell you to use Jev everywhere. Though, I got early access to TypeSafe/Jev, and spent the last 5 days trying to answer a deceptively hard question: where does Jev actually belong in a real codebase? - https://jevx.live After several failed approaches, pattern experiments, datasets, and studying and training with 44 open-source projects, After 4 versions, JevX v0.4.0 is the result — a tool that analyzes your codebase, finds places where deterministic rules may actually be making semantic decisions, and evaluates whether Jev is a good fit. JevX combines learned patterns, code structure, AI reasoning, and TypeSafe/Jev validation to produce a fit score instead of blindly suggesting Jev everywhere. The default cutoff is 70%, but you can change the threshold depending on how aggressive you want the analysis to be. The goal is simple: find where Jev should be used — and equally importantly, where it shouldn't. JevX 0.4.0 is now public. https://jevx.live npm i -g @vij-sameerb5/jevx Not just a terminal CLI. ⚡ Run it instantly with npx @vij-sameerb5/jevx 🧣 Use it directly through MCP with Claude, Cursor, Windsurf, VS Code, Gemini & Codex. this is still in building stage, It’s open source. If you find an issue, have an idea, or want to build on it — open an issue or PR on GitHub. #jev #AI #typesafe
