Agent Loop

The core iterative execution cycle of an agentic AI system: Perceive, Reason, Act, Observe, Repeat. At each iteration, the agent assembles context, invokes an LLM to reason and select an action, executes via tools, observes the result, and feeds it back into the next iteration—continuing until the task is complete. The agent loop is the architectural pattern that distinguishes AI agents from simple chatbots.
