description

Shared canonical references for product-design frameworks — Pyramid Principle, Working Backwards, Double Diamond, research design, methodology selection. Consumed by `product-discovery`, `product-strategy`, `working-backwards`, and `customer-research` via `${CLAUDE_PLUGIN_ROOT}/skills/product-design-shared/references/`. Do NOT invoke this skill directly — it has no orchestrator and no templates. Load the upstream skill that owns your task (`product-discovery` for PRD / HMW / EARS, `product-strategy` for Rumelt / Wardley / Minto, etc.) and let it pull from this pool as needed.

product-design-shared — references-only pool

This skill exists so the four product-design skills above can share one canonical copy of each framework reference. It has no SKILL behavior: no role prompts, no orchestrator, no templates, no slash command.

What lives here

references/pyramid-principle.md	Minto Pyramid composition discipline
references/working-backwards.md	Amazon Working Backwards 5-stage flow + PR/FAQ
references/double-diamond.md	Discover / Define / Develop / Deliver, divergent-convergent shape
references/research-design.md	Hypothesis · null · MECE questions · methods · findings

Who consumes this skill

• product-discovery — for PRD drafting, HMW framing, EARS specs, Jobs-to-be-Done
• product-strategy — for Rumelt kernel, Wardley maps, Minto-structured argument
• working-backwards — for the 5-stage flow (Listen, Define, Invent, Refine, Test)
• customer-research — for hypothesis-driven research design

If you're trying to "use" product-design-shared, you probably want one of those four skills instead. Pick from references/methodology-selection.md.
