# install.sh — hub-guide skill installer for Claude Code
#
# Skills go to ~/.claude/skills/<name>/ where Claude Code auto-discovers them.
# Hooks can be configured manually (see README).
#
# Usage:
#   ./install.sh                        # Copy all 26 skills to ~/.claude/skills/
#   ./install.sh --link                 # Symlink (edits in this repo are live)
#   ./install.sh clean-code testing     # Install specific skills only
#   ./install.sh --link clean-code      # Symlink specific skills
#
# Requires: Claude Code
