Koskamo

jev-use MCP

A community plugin for Claude Code, Codex, and pi that offloads decision-making steps to the Jev judgment model. It provides typed yes/no, pick-one, and score judgments in batched calls, enabling faster agent steps with fewer tokens. It supports typed escalation back to the LLM when Jev cannot decide, acting as a collaborator for tasks needing no text output.
