Other agents shell out to rg, grep, find, and bash. On many machines those binaries don't exist, and on the ones where they do, every call costs a fork-exec round-trip. omp links the real implementations into the process. ripgrep, glob, find: in-process. brush is the bash — with sessions that survive across calls, and 46 vendored coreutils (ls, sed, sort, xargs, even jq via jaq) that run as in-process builtins, zero fork/exec. The same omp binary runs on macOS, Linux, and Windows — no WSL bridge.

## Roughly **~80,000** lines of Rust, doing the work other harnesses shell out for.
Nine crates, one platform-tagged N-API addon. Search, shell, AST, highlight, PTY, desktop control, image decode, BPE counting — all in-process on the libuv pool. No fork/exec on the hot path. Another ~77k lines ride along vendored: the brush bash fork, a jq engine (jaq), and 46 uutils coreutils compiled straight into the shell.
