Agent

An Agent is an autonomous software system (often LLM-driven) that perceives its environment, makes goal-directed decisions, and executes multi-step actions without continuous human oversight.

This is the next-generation automation layer: a software entity capable of independent operation. Agents utilize a core perception-action loop, integrating memory and planning systems to break down complex objectives (e.g., 'book a full business trip') into actionable subtasks. They are distinguished by their autonomy, moving beyond simple chatbots or rule-based scripts. Modern examples like AutoGPT and Devin AI demonstrate their capacity to use external tools (APIs, web browsers) and adapt their strategy in real-time, delivering a step-change in efficiency for enterprise workflows and complex data analysis.
