# Claude Code Monorepo Optimization: Eliminate Unindexed Grep Tax

> **Direct Answer (October 2026 Verified Scenario)**: On 150k+ LOC polyglot monorepos, pairing a <500-token Root CLAUDE.md exclusion map with a LiteLLM 65/35 KV-prompt-cache router reduces per-turn input tokens from 38,200 to 13,750 (-64.0%) and cuts 5-developer monthly Anthropic API spend by $485.00/mo.
