diagnosis of the technology problem or decision, supporting arithmetic or cost calculations, a prioritized list of concrete actions to take, and a typed deliverable summarizing the recommendation — all grounded in practical, AI-era thinking without unnecessary complexity.","failureModes":["Vague or underspecified question may produce generic advice rather than targeted diagnosis","Missing

when you want diagnosis plus arithmetic plus concrete next steps in one response. Prefer this over generic LLM prompting when you need a consistent, typed deliverable format with a technology-specialist framing.
