# Skills library Taskfile.
#
# Primary entry point for project + host installation. Consumer projects
# do NOT depend on this file directly — they ship their own
# `skills:install` target that delegates here via `install.sh`. This
# Taskfile is invoked by maintainers of the skills repo itself, plus by
# install.sh during the post-clone wire step.
