Semble – Code search for agents that uses 98% fewer tokens than grep

Semble is an open-source code search tool designed for AI coding agents like Claude Code, enabling them to find relevant code snippets using 98% fewer tokens than traditional grep-based searches. It solves the problem of agents wasting tokens by reading entire files or launching subagents when direct lookups fail. This makes it particularly valuable for developers working with large codebases who want more efficient, cost-effective agent interactions.
