# hello.yaml: the smallest possible Horus workflow.
#
#   horus run hello.yaml
#
# One task runs a shell command that writes a greeting to its output artifact.
# `$message` expands to the on-target path of the artifact whose id is
# "message"; the command makes the output directory first so the redirect
# succeeds. Outputs and per-task scratch land under ./horus-out and ./horus-work.
