Agentic hardware co-design from brief to KiCad, firmware, 3D review, and explicit fabrication blockers. For 13 supported board families, hw-codesign turns a prompt into a reviewable candidate while keeping missing sourcing, toolchain, manufacturing, and physical evidence visible instead of silently treating it as success.
