## Pre-requisites - git: !`which git 2>/dev/null || echo "not installed"` - repo root marker: !`find . -maxdepth 3 -name "plugin.json" -path "*/.claude-plugin/*" -type f` - skill roots: !`find . -maxdepth 2 -type d -name skills -path './han-*/skills' ! -path './han-plugin-builder/skills' 2>/dev/null | sed 's|^\./||' | sort` - agents directory: !`find . -maxdepth 2 -type d -name agents -path './han-*/agents' 2>/dev/null | sed 's|^\./||' | sort` **If any of the above are empty or read `not installed`:** this skill is intended to run inside the Han plugin repository.
