What Jev does in openwork
The project describes itself this way: Open-source Claude Cowork alternative whose eval testkit can use Jev as a typed verification judge for agent-produced work. 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.
Verification
Verified. We confirmed this repository and its Jev relevance through the GitHub API and the source lists below. A specific file link has not been recorded yet.
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.
