Stop LLM Agent Hallucination · Live · April 25

How to Stop LLM Agents From Hallucinating in Production

LLM agent hallucination is not a model problem — it is an architecture problem. This live workshop teaches you the context engineering techniques that prevent hallucination by design: citation-grounded RAG, semantic blueprint constraints, and safeguards that catch fabricated outputs before they cause damage.

About This Workshop

Why LLM Agents Hallucinate — and the Architectural Fix

LLM agents hallucinate when they are asked to generate claims without grounding in verified sources, when context windows overflow with stale or irrelevant information, or when there is no output validation layer to catch fabrications. Context engineering solves all three causes structurally.

🧠

What is Context Engineering?

Context engineering is the discipline of designing systems that give AI the right information, in the right format, to reason and act reliably. It goes beyond prompt engineering — building structured, deterministic systems that scale in production rather than depending on fragile prompts.

🤖

What is a Multi-Agent System?

A multi-agent system uses multiple specialized AI agents working together — each with a defined role, context, and tools — to complete complex tasks no single agent could handle reliably. Context engineering is the key to making them work predictably.

🔗

What is the Model Context Protocol?

MCP is Anthropic's open standard for connecting AI models to tools, data sources, and other agents. It provides a structured way to orchestrate multi-agent workflows with clear context boundaries — making systems transparent and debuggable.

🎯

Why Attend as a Live Workshop?

Context engineering concepts require hands-on practice to truly understand. This live workshop lets you build a working system with a world-class instructor answering your questions in real time — far more effective than reading documentation alone.

Workshop Curriculum

What This 6-Hour Workshop Covers

Six modules. Six hours. A production-ready context-engineered AI system by the time you finish.

01

From Prompts to Semantic Blueprints

Understand why prompts fail at scale and how semantic blueprints give AI systems structured, goal-driven contextual awareness that scales reliably.

02

Multi-Agent Orchestration With MCP

Design and orchestrate multi-agent workflows using the Model Context Protocol. Build transparent, traceable agent systems that coordinate reliably.

03

High-Fidelity RAG With Citations

Build retrieval augmented generation pipelines that deliver accurate, cited responses. Engineer memory systems that persist context reliably across agent interactions.

04

The Glass-Box Context Engine

Architect a transparent, explainable context engine where every decision is traceable. Build AI systems that are predictable and debuggable in production.

05

Safeguards and Trust

Implement safeguards against prompt injection and data poisoning. Enforce moderation, trust boundaries, and access controls in multi-agent environments.

06

Production Deployment and Scaling

Deploy your context-engineered multi-agent system to production. Apply patterns for scaling, monitoring, and maintaining reliability under real-world load.

Frequently Asked Questions

Frequently Asked Questions

Common questions about the workshop, what to expect, and how to prepare.

Why do LLM agents hallucinate more than single-call LLMs? +

LLM agents hallucinate more than single-call LLMs because each agent interaction adds to the context window, stale information from earlier turns persists and influences later outputs, and multiple agents can reinforce each other's hallucinations when they share context without independent verification. Context engineering prevents this through explicit context management and per-agent RAG grounding.

What is the most effective way to stop LLM agent hallucination? +

The most effective hallucination prevention is citation-grounded generation — requiring every factual claim in an agent's output to be explicitly attributed to a retrieved source. When the agent cannot cite a source, it must flag the claim as uncertain rather than generating it confidently. This RAG-with-citations approach, combined with semantic blueprint constraints that limit agents to their specific domain, dramatically reduces hallucination in production.

How does the Glass-Box architecture help prevent LLM agent hallucination? +

The Glass-Box architecture makes hallucination visible and catchable. Because every context passing step and agent output is logged and traceable, you can identify when an agent generated an uncited claim, which context led to it, and which downstream agents were affected. This observability allows you to detect hallucination patterns and improve your safeguards systematically rather than discovering failures in production.

Can safeguards completely eliminate LLM agent hallucination? +

No system completely eliminates LLM hallucination, but the architectural safeguards taught in this workshop reduce it to manageable levels for production use. Citation grounding, output validation, and domain-constrained semantic blueprints together catch the vast majority of hallucination events. The Glass-Box logging layer helps you identify and address the remaining edge cases over time.

What is context window overflow and how does it cause hallucination? +

Context window overflow occurs when the accumulated context for an agent exceeds its effective context window, causing the model to lose track of earlier information, contradict itself, or generate outputs disconnected from the actual task. The memory engineering techniques in this workshop — including context compression, selective retrieval, and explicit context lifecycle management — prevent context window overflow from causing hallucination.

How do I validate LLM agent outputs to catch hallucination before users see it? +

The workshop covers output validation patterns including: citation verification (checking that claims reference retrievable sources), factual consistency checking between agent outputs in the same workflow, domain constraint validation against semantic blueprint specifications, and confidence scoring that flags uncertain outputs for human review. These validation layers form a hallucination defense-in-depth architecture.
