The hard part is generating code that's right for your system, team conventions, and past decisions. That's a context problem that naive RAG, MCP servers, and bigger context windows don't solve. Without the right context, that code costs you twice: once in tokens, again in long review cycles. This session is a practitioner's guide to building a context engine: the reasoning layer that brings together your organizational context and delivers only what the agent needs for the task at hand. I'll walk through the challenges that matter: reasoning across conflicting sources, maintaining permissions, and personalizing results based on who's asking and what they're working on. Along the way, we'll go deep on specific components with live demos and technical breakdowns. Drawn from real lessons building this in production, including what we got wrong. ## Full article daily.dev links to this article rather than hosting it.
