Agentic Systems and Design Patterns

Over the last two years, the industry has moved from simple chatbots and retrieval-augmented generation pipelines to something fundamentally more powerful: agentic systems . These systems do not just answer questions; they plan, act, observe the consequences of their actions, and keep iterating until a goal is achieved. Whether it is Cursor writing and debugging code, Perplexity performing multi-step research, Manus executing complex tasks through code, or Gemini Deep Research producing long-form investigative reports, the underlying architecture is agentic.
