Understand and build autonomous, tool-enabled AI agents in n8n that reason, choose actions, and call external tools (APIs, DBs, other agents). Learn config, output-parsing, and real-world patterns for agent-driven automations.

Learning Objectives — by the end of this lecture students will be able to:

• Describe the Tools Agent concept and when to use an agent vs. a normal node.

• Configure an agent: set prompts, system messages, max iterations, and enable streaming.

• Attach and author tool sub-nodes (HTTP, DB, other agents) so the agent can perform actions.

• Enforce structured outputs with parsers and validate responses for safe downstream processing.

• Design agent decision logic for retrieval, orchestration, and multi-step automations.

• Integrate agents with different chat models and understand model-availability trade-offs.

• Build multi-agent orchestration flows and safely expose agent capabilities as composable tools.

Key Topics & Patterns

• Prompt setup and dynamic input sourcing (previous node inputs, expressions).

• Tool execution lifecycle: select tool → call → format result → continue reasoning.

• Require Output Format: use output parsers to return JSON/structured data for reliable automation.

• Max iterations & safety: prevent infinite loops and bound agent reasoning cycles.

• Streaming responses for long-running tasks and UX-friendly outputs.

• Tool sub-nodes and multi-agent patterns: use agent nodes as tools for orchestration and complex pipelines.

• Templates & real-world examples: chatbots, retrieval workflows, WhatsApp integrations, and automation starters.

Use retrieval + LLMs to answer from your own documents — ground model responses with chunking, embeddings, and similarity search to reduce hallucinations and keep answers up-to-date.

Learning Objectives — by the end of this lecture students will be able to:

• Define Retrieval-Augmented Generation (RAG) and explain why combining retrieval with LLMs reduces hallucination and improves factuality.

• Describe the core RAG architecture: document store, chunking, embeddings, vector database/index, retriever, and the LLM (generator).

• Prepare data for RAG: split documents into chunks, create embeddings, and index them in a vector DB.

• Implement the query pipeline: embed queries, run nearest-neighbour similarity search, and (optionally) rerank retrieved chunks.

• Build prompts that feed retrieved context to the model and include explicit instructions (e.g., “use only the provided sources; otherwise say ‘I don’t know’”).

• Choose and apply output-format constraints and citation/display strategies so downstream systems can trust and use model outputs.

• Identify operational concerns—freshness, privacy/access control, cost (embeddings + LLM calls), and evaluation strategies—and apply mitigations (re-indexing, caching, low temperature, tests).

Key Topics & Patterns

• Architecture & components: Document Store → Chunking → Embeddings → Vector DB → Retriever → LLM generator.

• Data prep: smart chunking, embedding creation, and efficient indexing for fast similarity search.

• Retrieval patterns: retrieve-then-generate and rerank-then-generate; how and when to use each.

• Retrieval lifecycle: embed query → search top-K → (optional) rerank → build prompt → generate answer.

• Output reliability: require structured outputs, force citations or “don’t know” responses, and validate for downstream automation.

• Safety & robustness: bounding context, low temperature, caching common responses, and regular re-indexing for freshness.

• Real-world templates & examples: FAQs, internal knowledge bases, product docs, research assistants, and retrieval-backed chatbots.

Ideal For

Intermediate to advanced AI developers, ML engineers, knowledge managers, and product teams who want to build systems (chatbots, internal search, research assistants) that combine vector retrieval with LLMs to produce grounded, auditable, and maintainable answers.
