# =============================================================================
# install.sh — cross-tool installer for the java-development skill
#
# Detects which AI coding tools are installed (Claude Code, Codex, OpenCode,
# ZCode) and installs the skill into each tool's discovery directory.
#
# Usage:
#   ./install.sh              # install everywhere it can
#   ./install.sh --force      # overwrite existing installs in detected tools
#   ./install.sh --all        # install to every supported tool directory
#   ./install.sh --uninstall  # remove from all tools
#
# Works on macOS, Linux, and Windows (Git Bash / WSL).
