# clone-pi-brain — create a new content-only pi-brain clone for your project.
#
# With package-resolved resources, the installed pi-brain package provides
# skills, prompts, themes, tools, personas, and the extension. A clone only
# needs content, config, and project-specific docs.
#
# Usage:
#   bash tools/clone-pi-brain.sh <target-dir> [org-name]
#
# Example:
#   bash tools/clone-pi-brain.sh ~/projects/acme-brain "Acme Inc"
