# okf — the okf CLI, backed by its Docker image (no Ruby on the host).
#
# Installed on your PATH by https://docker.okfgem.com/install.sh, this makes
# `okf validate .`, `okf lint .`, and `okf server .` run the image with your
# current directory mounted at /data. For `server` the port is published and the
# bind address is opened for you. It is the same interface as the native CLI, so
# the agent skill, the docs, and your muscle memory all work unchanged.
