Use this skill for platform product management challenges in B2B or enterprise SaaS contexts. Invoke it when someone needs help thinking through: how platform capabilities should be structured across architecture layers; writing PRDs for platform features like permissions, multi-tenancy, or APIs; mapping user journeys for multi-role platforms (admins, members, guests); zero-to-one platform design or one-to-ten scaling strategy; event tracking schemas, north star metrics, or post-launch analytics for a platform product. Trigger for any request involving platform product design, platform architecture, platform PM work, or platform product strategy — even if the user doesn't say 'platform' but describes a multi-tenant, multi-role, or layered product problem.
