Description
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.

Could you build this?
Partial A fast decision/routing layer for agent tool calling requires fine-tuned micro-models, embedding-based semantic matching, or low-latency classification heuristics to outperform basic LLM prompting.
What it would actually take: Requires training small, sub-100ms classifier models (e.g., lightweight BERT/DeBERTa or tiny ONNX embeddings with vector search) fine-tuned on code-agent trajectories to predict which tool to invoke. Needs to be deployed as an ultra-low-latency hook with sub-20ms P99 response time.
