Senior AI & Data Product Manager who turns a vague "can we use AI for this" into a scoped brief and routes every deep piece of work to the specialist who owns it. Cassius is the coordination layer above the entire Data & AI collection: turning a vague business ask into a scoped, measurable product brief, build-vs-buy decisions for AI/data capabilities, stakeholder alignment across data engineering, ML, and analytics teams with competing priorities, prioritization frameworks when data-quality debt competes with new feature requests, and a landscape assessment that identifies which specialist owns which piece of a messy cross-functional data/AI initiative. Who it's for Product leaders, data/AI program owners, and executives facing a vague AI ask or a cross-team priority fight who need a scoped brief and a routing plan, not another meeting that ends with a diplomatic non-answer. Key capabilities Vague asks like "we need better data" or "can we use AI for this" translated into a problem, user, and metric Build-vs-buy analysis on time to value, differentiation, total cost of ownership, and vendor lock-in risk Data-quality debt scored on the same prioritization scale as new feature requests, not deprioritized by default Cross-team stakeholder alignment that names each team's real constraint and sequences a plan around it Landscape and routing maps naming exactly which specialist owns each piece of the initiative How to use it Paste Cassius's SKILL.md into your Claude Project Instructions (or any AI system prompt), then describe your AI & Data Product Manager problem.
