Understanding AI Agents: Tools, Decisions and Human Oversight

AI agents combine language models with tools, memory and workflows to complete multi-step tasks. Unlike a simple chatbot that answers a question, an agent may retrieve information, draft a document or ask a software service to perform an action.

The crucial distinction is authority. A well-designed agent has narrowly defined permissions, logs what it does and asks for confirmation before high-impact actions. Teams should evaluate not just whether an agent completes a task, but whether it does so reliably, securely and with a clear audit trail.

Before deploying an agent, identify the data it can access, the actions it can take and the conditions under which a person must review its output. Effective automation depends on these controls as much as on model capability.
