RAG, Clearly Explained

Build your own RAG (Retrieval Augmented Generation) agent in 25 minutes. If you're building AI products, or you want to be, you've heard the term thrown around. We believe in learning by doing, so on this episode we teach you how to build your own RAG agent from scratch. You'll learn key terminology like vector store and embedding, and you'll have a working agent by the end. Walk away with the confidence to talk about RAG with your business and technical stakeholders. The workflow examples from this episode are available for download on Github here. Simply open a new workflow, click the import from URL button, and paste the link from Github. A step-by-step guide can be found here.

3 Important Lessons For Creating Production Grade Agents

Wondering how to take your proof of concept agent to production? Ilan walks through three key lessons from building a competitive analysis agent in n8n, including tips for optimizing your prompts, how to break work into sub-agents, analyze logs, and rethink your workflow design. CHAPTERS 00:00 - Intro and Episode Overview 01:31 - Sponsor: Querio 01:59 - The Competitive Analysis Agent Problem 04:29 - Lesson 1: Use Observability and Logs to Debug 06:43 - Hitting Token Limits and Iteration Caps 09:05 - Lesson 2: Split Into Sub-Agents When Needed 12:40 - The Parallel Processing Problem in n8n 14:11 - Lesson 3: Sequential Design When Tools Don't Run Parallel 16:29 - Wrapping Up and Key Takeaways KEY LESSONS Lesson 1: Use observability and logs to debug agent performance. When the market research agent missed a $100M Series C raise, analyzing n8n logs revealed superficial Perplexity requests, leading to prompt optimization techniques like specifying exact information types (official news, product updates, partnerships, industry coverage) instead of letting the agent decide what to search for. Lesson 2: Split into sub-agents when hitting limits or performance issues. Token limits (10,000 per second on Anthropic) and iteration caps (10 default in n8n) mean one agent doing too many jobs leads to context growth and hallucination risk. Breaking into focused sub-agents (news researcher, sentiment analysis) with specific prompts solves this. Lesson 3: Design for sequential execution when tools don't support parallel processing. n8n runs left to right, top to bottom, so forcing a parallel-looking workflow creates unpredictable execution order. Accepting sequential design and removing deterministic steps (like pulling competitor lists from Google Sheets) from agent control improves reliability.
