The README opens with

Faster agent decisions. Models, subagents, skills, MCP tools, CLIs and plugins become one candidate set — Jev answers one typed Choice question, JevRouter enforces availability, permissions, risk and confirmation around it.

Agents waste reasoning tokens on a question a fast decision model answers better: which capability should handle this next? JevRouter puts Jev — a System One model that turns structured state into typed decisions with probability distributions — in front of your tools, while your reasoning model stays the execution and fallback layer.
