What you will be able to do

• You will be able to explain, in one sentence, why an agent is different from a chatbot and when you actually need one.
• You will be able to read any agent's behaviour as a loop of think, act, observe, and spot where it goes wrong.
• You will be able to build an n8n workflow end-to-end: trigger, transform, branch, and send.
• You will be able to add an LLM node with a system prompt and tools so the workflow decides what to do on its own.
• You will be able to wire a WhatsApp bot that receives a message, generates a reply, and sends it back automatically.
• You will be able to give an agent memory, put it on a schedule or webhook, and ship it with limits, tests, and a kill switch.
