Search codebases with the sift CLI using indexed grep. Builds a trigram index once, then runs ripgrep-compatible queries 2 to 3x faster by skipping irrelevant files. Use when exploring a repository, finding symbols or patterns, grepping across a large codebase, or when the user mentions sift, indexed search, or .sift. Also use when the user wants faster grep results or is searching a repo with more than a few thousand files. Not for developing sift itself (crates/cli, sift-core, clap, cargo test).
