01. What is an Agent?

Agent Definition

Plain definition: An agent is a "virtual assistant that thinks for itself to get things done."

Core capabilities: planning, tool selection, tool execution, and summarization.

More formal definition: An entity that can autonomously perceive its environment and take actions to achieve goals.

Agent vs Workflow

In one sentence: An agent uses tools to autonomously figure out how to solve problems; a workflow follows preset steps and executes in a fixed way.

Analogy

  • Agent: like an intelligent assistant that understands your intent and figures out how to solve problems on its own
  • Workflow: like an assembly line that runs in a preset sequence of steps, suited to standardized processes

When to Use Which

  • Agent: suited to tasks that need intelligent decision-making
  • Workflow: suited to standardized, repetitive, fixed-process tasks
