Search Router

This is a routing guide that tells Claude which search tool to use for different query types to save tokens. The key insight is using TLDR search as the default for code exploration instead of grep, since it gives you 95% token savings. It breaks down when to use AST-grep for structural patterns, TLDR semantic for conceptual questions, and grep only as a last resort for literal text. The decision tree is solid and the token comparison table makes the efficiency gains concrete. If you're working with Claude on a large codebase and burning through context with inefficient searches, this gives you a practical playbook for staying within budget.
