Coding / product dossier
Routes coding-agent tool calls through a Codex hook or skill, using Jev for ambiguous choices.
Product brief
Harness Router is a decision layer for AI coding agents that makes tool selection faster, cheaper, and more reliable before execution. Use it as a Codex hook to automatically route every tool call, or as a skill when the agent should invoke routing explicitly. Obvious decisions stay on the fast path, ambiguous choices are resolved with Jev, and complex multi-step decisions can escalate to MCTS.
Why we selected it
A technically distinct tool-selection layer for coding agents, with a Codex hook and a natural connection to the recent JEV model news.
