Choose a Pattern
Each exercise targets one agentic design pattern — from Prompt Chaining to Multi-Agent Collaboration.
Build & Simulate
Drag agent blocks onto the canvas, arrange them, and hit Run. Watch your architecture succeed or fail in real-time.
Why Practice Beats Reading
Building agent architectures yourself creates understanding that sticks.
Learn by building, not reading
Drag agent blocks, arrange them into architectures, and run simulations. Mistakes teach you more than documentation ever could.
Instant feedback on every decision
Skip a validation gate? The simulation shows you exactly what breaks. Add a distractor block? Your score drops. Every choice has visible consequences.
Production-grade thinking
Each exercise scores you on architecture correctness, resilience, and efficiency — the same criteria used in real system design reviews.
21 patterns, 21 challenges
Cover every pattern from Antonio Gullí's framework: prompt chaining, routing, parallelization, reflection, tool use, planning, multi-agent, RAG, MCP, and more.
What an Exercise Looks Like
Each exercise gives you a mission, a set of agent blocks, and a canvas to build on.
Build a Customer Support Pipeline
Assemble an agent pipeline that extracts intent, validates the extraction, analyzes sentiment, and generates a response.

Common Questions
Practice Agentic Patterns provides 21 interactive drag-and-drop exercises where you build real AI agent architectures. Each exercise teaches a specific agentic design pattern — like prompt chaining, routing, parallelization, or multi-agent collaboration — by having you assemble agent blocks, connect them, and run a simulation to see how your architecture performs.
The best exercises combine architecture building with instant feedback. Here, you drag agent blocks (like Extraction Agent, Validation Gate, Classifier) onto a canvas, arrange them in the correct topology, and simulate the data flow. You get scored on architecture correctness, resilience, and efficiency — teaching you not just what patterns exist, but why each component matters.
No coding is required. The exercises use a visual drag-and-drop interface where you focus on architecture decisions — which blocks to include, what order to place them in, and how they connect. This teaches the design thinking behind agentic systems, which you can then apply in any framework (LangChain, CrewAI, AutoGen, etc.).

All 21 patterns from Antonio Gullí's framework: Prompt Chaining, Routing, Parallelization, Reflection, Tool Use, Planning, Multi-Agent Collaboration, Memory Management, Learning & Adaptation, State Management (MCP), Goal Monitoring, Exception Handling, Human-in-the-Loop, Knowledge Retrieval (RAG), Inter-Agent Communication, Resource Optimization, Reasoning Techniques, Guardrails & Safety, Evaluation & Monitoring, Prioritization, and Exploration & Discovery.
Reading teaches you what patterns exist. Building teaches you why each component matters. When you skip the Validation Gate in a Prompt Chain exercise and watch the simulation fail with 'Hallucinated entities propagated,' you understand the pattern at a visceral level that no article can provide.
Senior developers, software architects, and technical leaders who want to go from reading about agentic AI to confidently building agent architectures. You should understand distributed systems and design patterns — we translate that expertise into agentic AI fluency.
Build the patterns. Build the intuition.
The best way to learn agentic design patterns is to build them yourself. 21 exercises. Zero theory walls. All practice.
