What is an AI agent?
An AI agent is software that can work towards a goal by interpreting information, deciding what to do next and using approved tools. A chatbot mainly produces a response. An agent may also search knowledge, update a CRM, prepare a quote, request approval or trigger another system.
The term is used loosely. Many useful “agents” are controlled workflows with an AI decision inside them. That is often preferable to broad autonomy because the steps, permissions and failure modes remain visible.
What is agentic AI?
Agentic AI describes systems designed to take a sequence of actions rather than answer a single prompt. They may plan, call tools, inspect results and choose the next step. The useful question is whether that autonomy improves the outcome enough to justify its added risk and complexity.
What is AI agent orchestration?
Orchestration is the control layer around one or more agents. It decides which capability handles a task, what context it receives, which tools it may use, when a person must approve an action and what happens when something fails.
Router
Classifies work and chooses the appropriate workflow or specialist capability.
Context
Provides only the relevant data, instructions and permissions.
Guardrails
Constrain tools, spending, recipients and sensitive actions.
Evaluation
Checks quality and exposes uncertain cases for human review.
Single agent or several?
Multiple agents help when work has genuinely distinct roles, permissions or evaluation criteria. They are not automatically better. A single deterministic workflow is usually easier to operate, test and secure.
Where agents work well
- The task has a clear goal and bounded actions.
- Necessary information is accessible and reasonably reliable.
- Quality can be checked before consequential action.
- There is a useful fallback when confidence is low.
- Cost, errors and changing behaviour can be monitored.
Where caution matters
High-impact decisions, sensitive personal data, irreversible changes and loosely defined goals need stronger controls. An agent should not silently invent policy, approve its own exceptions or acquire wider access for convenience.
