Foundational Agent Patterns
AGAI 202 · Module 1
Begin with the core architectural patterns used by modern AI agents: ReAct loops and plan-and-execute systems. These patterns explain how agents alternate between reasoning, tool use, observation, and replanning.
Lessons in this module
The ReAct Pattern
Learn how the ReAct pattern combines reasoning and tool use into a flexible loop that powers many practical agents.
Plan-and-Execute Architecture
Explore architectures where an agent first creates a plan, then executes steps while observing progress and replanning when necessary.
Reactive versus Planned Agents
Compare reactive and planned architectures and learn how to choose the right pattern for different application requirements.
