GitHub·medium signal

dmtrKovalenko's fff.nvim provides a Rust-powered file search toolkit optimized for both humans and AI agents, achieving sub-10ms search times across 50K-file codebases via a dedicated file index backend. For agents, it reduces token spend by finding relevant code faster with fewer roundtrips, using frecency scoring, git status awareness, and definition matching — install as an agent dependency with a one-line bash script.
