¿Qué es un agente de IA? Guía completa de arquitectura de sistemas autónomos
AI Agents have transitioned from theoretical research to the backbone of enterprise automation. An agent is an autonomous entity capable of sensory perception, stateful memory persistence, goal decomposition, and external tool execution.

Passive Chatbots vs Active Autonomous Agents
Passive LLMs execute single-pass text generation. Agents operate in continuous cyclical feedback loops (Perceive -> Reason -> Act -> Observe -> Reflect). They handle non-deterministic environments and self-correct on runtime exceptions.
Cognitive Architectures: ReAct, Plan-and-Solve, Reflexion
Understand the mechanics of ReAct decision framing, dynamic plan reformulation, and introspective error recovery loops in modern agentic design.
Tool Execution Protocols and Model Context Protocol (MCP)
Explore how standardized schemas enable LLMs to safely query databases, trigger API mutations, and manipulate local development environments.
Production Guardrails: Circuit Breakers and Human-in-the-Loop
Eliminate runaway execution loops, enforce strict iteration timeouts, and implement approval gates for destructive production actions.
