# A skill is a folder, and each assistant reads the same layout from its own
# folder. This installs each skill into every assistant found in your user
# folder: .claude\skills, .codex\skills and .grok\skills. An existing copy of the
# same skill is replaced. To install somewhere else, set AURAOFFICE_SKILLS_DIRS
# to a semicolon-separated list of skills folders.
#
# The AuraTrack skill works through auratrack-cli, so installing it also puts
# auratrack-cli 0.2.0 in %LOCALAPPDATA%\AuraOffice\bin, checked against
# the hash below, and adds that folder to your PATH. The skill holds no
# credentials: you sign in once with `auratrack-cli login`.
