Your n8n AI agent probably isn’t broken. You skipped one idea at the very start — and this lesson is that idea, taught properly in under nine minutes.
This is Lesson 1 of “Agents That Actually Run”, a free 8-part n8n series from TechGuardian Academy. By the end of this video you will have a real workflow running on your own screen: a trigger, two nodes, and data moving between them. No prior automation experience needed.
Most n8n tutorials hand you the parts — a model, a tool, a prompt — but never the structure. That’s why the agent runs, answers confidently, and turns out to have done nothing. We fix that here, at the foundation.

WHAT YOU’LL BE ABLE TO DO
━━━━━━━━━━━━━━━━━━━━━━
• Build a workflow from an empty canvas (trigger → node → node)
• Read the output data panel and understand what an “item” actually is
• Use {{ $json.field }} to pass a value from one node to the next
• Tell Fixed and Expression apart — the #1 reason beginners see their text printed literally
• Diagnose the three failures this exact setup produces
WHAT YOU NEED
An n8n account. The free cloud trial covers this entire series. Nothing else, no credit card, no paid nodes.

THE SERIES — “Agents That Actually Run”
━━━━━━━━━━━━━━━━━━━━━━
1. What a workflow actually is ← you are here
2. Reading the data between nodes
3. Your first agent, and what it really does
4. Why your agent lies about what it did
5. Giving an agent memory without breaking it
6. Tools, sub-agents, and when each is wrong
7. Cost, retries and rate limits
8. Putting one in front of a colleague
Foundation lessons assume nothing. Depth lessons name their prerequisite up front, so you never land in the wrong one.
