From your coding agent
Any agent that can run a shell command can use it. The one-shot form prints the answer and exits:
cdu report.pdf -p "List the material risk factors, with citations."
A skill for Claude Code and similar agents ships in the repository (skills/hunterrag-corpus): it teaches the agent to cite unit addresses, not line numbers.
