Write a PRD for a physical hardware product — target cost (BOM and landed), industrial design constraints, regulatory certifications, reliability targets, serviceability, packaging, and forecast assumptions. Use when asked to write a hardware PRD, spec a new device, define requirements for a physical product, or kick off an NPI program. Produces a complete hardware PRD with a cost stack, cert matrix, reliability spec, and EVT/DVT/PVT milestone targets.
What to give it
▸Product concept and user — what it is, who buys it, key use environment (indoor/outdoor, temp range, drop risk)
▸Target retail price and channel — retail vs D2C changes the margin stack
▸Target markets — determines the cert list (US, EU, UK, etc.)
▸Power source — battery (chemistry, size) vs mains changes safety certs entirely
▸Forecast — units for year 1 and lifetime, plus confidence
▸Launch window — and any hard date (e.g. holiday season)
✅ The bar it holds itself to
Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.
✓Every requirement is testable — a DVT engineer could write a pass/fail test from it
✓Cost target includes landed cost and survives the channel-margin math
✓Every target market has its certs listed with lead times
✓Reliability targets are numbers, not adjectives ("robust" is not a spec)
✓Forecast assumptions are explicit enough to size tooling and MOQs against
✓Battery products name chemistry and the UN 38.3 / IEC 62133 path
⚠️ What it refuses to do
Do not state a cost target without saying which layer it is — "$40 target" that turns out to be BOM-only kills the margin at landed
Do not write "certified for global markets" — name each market and each cert
Do not spec reliability as "high quality" — give MTBF, return-rate ceiling, and abuse cases
Do not omit serviceability — an unrepairable design is a warranty-cost decision, so make it consciously
Do not hide forecast uncertainty — tooling cavitation and MOQs are bought against this number
