Frequently Asked Questions

What is an agentic workflow?

A workflow where an AI agent plans, executes, and adjusts a sequence of actions to achieve a goal, not just answer a single prompt.

How is an agent different from a chatbot?

A chatbot responds turn by turn, while an agent keeps state, calls tools, and can continue working without constant human prompts.

Do I need a multi-agent setup from day one?

No. Most teams start with a single well-scoped agent and later add more agents as the use case matures.

What tooling do I need for agentic systems?

You need orchestration (planner), memory, logging/observability, and reliable tool/API integrations.

How do I keep agents safe and aligned?

Use clear system policies, strict tool permissions, logging, and human-in-the-loop checkpoints for high-impact actions.

Where should I pilot agentic workflows?

Start with internal workflows that have clear success criteria and low external risk, such as dev tooling or internal support.
