Hardware PRD Skill

A software PRD can ship wrong and patch later; a hardware PRD is cut into steel and soldered onto boards. This skill writes a PRD that forces the decisions that get expensive after tooling: cost targets with a full stack (not just BOM), certifications named per market, reliability as numbers, and forecast assumptions stated so the supply chain can be sized honestly.

What This Skill Produces

• A complete hardware PRD with numbered, testable requirements (shall-statements)
• A target cost stack: BOM → COGS → landed cost, with margin math
• A regulatory/certification matrix per target market
• Reliability, serviceability, and packaging requirements with acceptance numbers
• Forecast assumptions and the EVT/DVT/PVT milestones the schedule hangs on
