ColGrep-Agent-2B: local 2B code-search agent cuts Claude Code tokens by 34%

LightOn released ColGrep-Agent-2B, an open 2B local code-search agent that sits between a coding agent and the repo; in their Claude Code tests on 52 questions across 13 repos, delegating search cut API tokens 34% and cache-aware cost 40% vs grep, with no statistically significant accuracy change. Install with brew install lightonai/tap/colgrep && colgrep --install-agent, then colgrep --install-claude-code (Codex and OpenCode hooks too).
