ColGrep-Agent paired with Field-Guide: reduce token usage by >30% in Claude Code

ColGrep-Agent, a newly released tool that uses a small local LLM to search a codebase, cuts token usage for frontier coding agents by a third, and a test pairing it with Field Guide reduced token usage by more than 30% in Claude Code, according to a Hugging Face blog post by lightonai. ColGrep-Agent answers only where code is located, while Field Guide identifies which system owns a component and what rules guard it, so the two tools address different questions and their savings stacked in the test.
