**Automatic model routing and token optimization for [Claude Code](https://docs.anthropic.com/en/docs/claude-code).**

Stop burning Opus tokens on simple searches. This project makes Claude Code automatically route cheap tasks to Haiku and reserve full reasoning power for complex work — saving **3-5x on token costs** with zero quality loss.

You: "find all python files that import pandas"
     → [ROUTING: T0_LOOKUP] → Delegated to Haiku subagent (cheap, fast)

You: "fix the null check in auth.py line 45"
     → [ROUTING: T1_STANDARD] → Answered directly (normal)

You: "security review the RLS implementation for bypass vulnerabilities"
     → [ROUTING: T2_DEEP] → Full Opus reasoning + specialized agents (thorough)
