Building Agents in Practice
Frameworks and no-code platforms for shipping real agents.
What you will learn
- ✓Common agent frameworks
- ✓No-code options like Copilot Studio
- ✓How to choose an approach
Explanation
You rarely build an agent from scratch. Code frameworks (LangChain, the OpenAI Agents SDK, LlamaIndex) handle the loop, tool calling, and memory plumbing.
No-code platforms like Microsoft Copilot Studio let teams build enterprise assistants visually with 'topics' (what to handle) and 'actions' (what to do), connected to business systems.
Choose code for flexibility and control; choose no-code for speed and non-developers.
Real-world use
Many companies prototype an agent in a no-code tool, then rebuild the winning ones in code for control and cost.
Common mistakes
- • Reinventing the loop, tool-calling, and memory by hand when a framework already does it.
Practice
Decide whether a small internal HR assistant should be built code-first or no-code, and justify it.
