claude-router

Overview

claude-router is a local prompt router that selects a Claude model tier and prepends a scaffold to prompts before API calls. It uses local embeddings to deterministically route eval, research, content, and review prompts, aiming to reduce spend on Sonnet and Opus when Haiku plus structure suffices.

Best for

Best for
Teams using Claude APIs who want to cut token costs on structured, repetitive prompts.

Use cases

• Route eval prompts to Haiku with a scaffold
• Cut costs on research prompts by using Haiku
• Standardize content and review prompts before API calls
