# OMNI OMNI runs on the machine, as a hook the agent host calls. It rewrites the output of a shell tool call before the model reads it, and every cut it makes leaves a marker and a handle to fetch the bytes back. No account, no telemetry, nothing about the machine leaves it. ## Install ``` brew install fajarhide/tap/omni omni init ``` Without Homebrew, take the release archive for the platform from <https://github.com/fajarhide/omni/releases>, pull the line for that archive out of the `SHA256SUMS` published beside it into a file of its own, and verify it with `sha256sum -c <that file>`, or `shasum -a 256 -c <that file>` on macOS. Then untar and put the binary on the path. Two things decide whether the check is worth anything. The manifest line has to reach the tool as a file rather than a pipe, because a `grep` that matches nothing sends an empty stream and macOS reads that as a pass, so a mistyped archive name would install unverified. And the verification has to gate the untar with `&&`, because a shell running pasted lines carries on past a failed one. **Do not name a host you have not established you are running in.** With no terminal to draw its menu on, which is the case when an agent runs it, `omni init` configures the host it is running inside and prints which one it picked. If it cannot name the host, a plain shell for instance, it stops and lists the flags rather than installing somewhere nobody asked for. Only then pick one: `--claude`, `--cursor`, `--codex`, ...
