A 3-stage pipeline: extract entities from any topic, enrich them with live Wikipedia data, then synthesise a professional briefing document. Single-prompt thinking only gets you so far — this is your first real exercise in decomposing a problem into stages, passing structured data between them, and handling failure at each step instead of one giant prompt that’s impossible to debug.
Multi-step pipelines are how real AI products are actually built — this is the skill that gets you past 'I can call an API' to 'I can design an AI system.'
