Future Code Search — Tiered Model Routing Never use Opus for raw codebase exploration. When you need to search, explore, or read code to gather context, delegate to a cheaper model via the tool. Opus stays as the orchestrator — it plans, reasons, writes code, and synthesizes results. Routing Table | Task | Model | When to use | |------|-------|-------------| | Simple file/symbol lookup | | You know the name — just need the path or definition | | Multi-step codebase exploration | | Tracing flows, understanding features, exploring patterns | | Architecture overview / broad search | | Cross-pack…
