Stop Blaming the Model: The Art and Science of Context Engineering and Architecture

We spend too much time chasing model benchmarks and not enough time engineering the architecture that feeds them. Most production AI failures are not caused by a lack of model intelligence, but by poor information design. If you are still relying on long-form prompting and naive RAG, you are building systems that are destined to hallucinate or break at scale. This talk moves past the hype of prompt engineering and dives into context as a persistent, versioned infrastructure. We will examine the shift from stateless chat sessions to structured context engineering, using a mental model borrowed from engineering management: setting boundaries, managing state, and delegating tasks through coordination protocols. We will cover technical areas like: - The evolution of AI coding workflows: Moving from iterative chat to spec-driven development and graph-based task management. - The limits of RAG: Why semantic similarity fails for complex business logic and how to build a core data layer with rich, structural metadata. - Decoupled Planning: A three-tier architecture that separates the planning phase from execution, allowing for human-in-the-loop validation and deterministic outputs. You will leave with a systematic framework for context architecture that replaces black box prompt tweaking with auditable, glass-box systems. Stop guessing with prompts and start engineering your state.
