+# whittle
+
+Cut your AI agent's token bill. Lose nothing that matters.
+
+This package installs the prebuilt `whittle` binary for your platform (macOS and
+Linux, arm64 and amd64). It is the npm distribution of
+[github.com/firstops-dev/whittle](https://github.com/firstops-dev/whittle); the
+same binaries also ship via `go install` and Homebrew.
+
+```sh
+npx @firstops/whittle setup     # one command: hook + local daemon + sidecar
+# or install globally:
+npm install -g @firstops/whittle && whittle setup
+```
+
+Full documentation, benchmarks, and the fidelity contract:
+[the repository](https://github.com/firstops-dev/whittle).
