What Jev does in jev-router (prismhq)

The project describes itself this way: Open-source LLM router that uses TypeSafe's Jev to pick a model, on top of LiteLLM. In the Agent tooling category, Jev typically decides which tool, skill or model to use next, whether a step is finished, and whether an action is risky enough to stop.

How Agent tooling projects use Jev

Agent tooling is where Jev sees the most experimentation. These projects sit inside coding agents and assistants such as Claude Code, Codex and Pi, and hand the many small, repetitive choices an agent makes to a fast decision model, leaving the large model free for reasoning and writing.
