Agents

An agent works through a process for you. Take a ready-made agent or build your own.

Prompt, skill, agent: what's the difference?

  1. PromptOne instruction.“Write a friendly payment reminder.”
  2. SkillWritten instructions for one task.Step by step, equally good every time.
  3. AgentAn assistant with a goal.Uses several skills and asks you before important steps.

Like a new colleague: a prompt is a single request, a skill is a written how-to, and an agent is the colleague who knows several how-tos and asks before important steps.

For pros
Prompt
A single message in a chat. Good for one-off tasks.
Skill
A SKILL.md file in the open Agent Skills format. The assistant loads it when a request matches.
Agent
Instruction plus skills plus tools such as a mailbox or calendar, optionally with a trigger. Works through several steps; you approve.

Frequently asked questions

What is an AI agent?

An agent is an AI assistant with a goal. It plans steps itself and uses tools and skills to do them, for example sorting emails and drafting replies.

How do agents and skills fit together?

A skill is the written instructions for one task. An agent combines several skills and tools to reach its goal.

Do I need to know how to code?

No. Visual builders are enough for a small first agent. Our guide shows the steps without coding.

What should I watch out for?

An agent acts on your behalf. Give it only the access it needs and keep important steps such as sending or paying for your own approval.
