# Architecting Enterprise AI Agents

AI agents extend beyond static chatbots by executing tools, planning sub-tasks, and maintaining persistent state.

## Core Agent Loop

1. **Perceive**: Extract user intent and contextual state.
2. **Plan**: Formulate step-by-step action trajectory.
3. **Execute**: Invoke external APIs/tools (databases, vector search).
4. **Reflect**: Verify output validity before returning final response.
