| Bottom line | r3bl-open-core runs shell or system commands and reads local files; restrict its folder reach, network access, and credentials before installing. | Use this tool only with non-sensitive construction documents, verify all takeoffs manually before relying on them, and keep it on isolated machines without access to other company systems or networks. |
