Скачать или смотреть Building Reliable AI Agents with Sub-Agent Context Isolation in Claude Code

Have you ever built an AI agent that starts strong, but over time, begins to "drift" and forget critical instructions? It's a frustrating problem that plagues many developers aiming to build reliable, enterprise-grade AI.

We spend a lot of time on "prompt engineering," but the solution to this problem is often deeper and more structural.

In this talk, I talk about **Context Engineering**: the deliberate practice of curating an agent's "working memory" to maximize signal and ruthlessly minimize noise.

You will learn:
[01:50] What is Context Engineering and its core practices: Precision Filtering, Hierarchical Summarization, Advanced Retrieval, and Contextual Scaffolding.
[14:51] The "Lost in the Middle" problem: Why LLMs naturally forget information and how to design systems that avoid this critical failure mode.
[20:47] A new mindset: How to use *sub-agents* not just as "roles," but as powerful tools for **context isolation**.
[37:09] A 3-phase workflow (Research, Planning, Implementation) for managing complex tasks with human-in-the-loop validation.

This is the methodology I use to move from "prompting" to "architecting" AI systems that are consistent, reliable, and predictable.
