Hardware design is locked behind electrical engineering expertise, expensive EDA tools, and fragmented knowledge across PCB layout, enclosure design, and component sourcing. Hardware Builder takes a natural language prompt and coordinates six Claude Opus 4.6 agents to return a complete project: bill of materials from a 14,758-component database, PCB circuit design with KiCad schematic, parametric OpenSCAD 3D-printable enclosure, step-by-step assembly guide, and a full USD quote. It exposes a REST API, an Agent-to-Agent protocol for programmatic invocation, and ships as a one-click OpenClaw skill putting end-to-end hardware prototyping in anyone's hands so even you can try it right now with one line
