# Install the Helm skill into a coding agent's skills directory.
#
# SKILL.md is an agent-neutral format, so the same folder works in Codex,
# Cursor, OpenCode, Claude Code and anything else that reads Agent Skills.
# All this script does is put skills/helm where a given agent looks for it.
#
#   ./install.sh                 # -> ~/.agents/skills  (the shared location)
#   ./install.sh codex cursor    # -> that agent's own directory as well
#   ./install.sh --copy          # copy instead of symlink (no git pull updates)
#   ./install.sh --uninstall     # remove whatever this script installed
#   ./install.sh --list          # show where Helm is currently installed
