Build Hour: Agents SDK

Build with the next evolution of the Agents SDK. In this Build Hour, you’ll learn how to use the updated Agents SDK to build long-running agents with a model-native harness. Give agents the tools, memory, and execution environment they need to work across files and systems — while staying flexible enough to fit your own stack.

In this session, Steve Coffey (Member of Technical Staff) and Nish Singaraju (Product, Agents) will cover how to:
• Build agents that can inspect files, run commands, edit code, and operate across multi-step tasks
• Use the updated Agents SDK harness for more reliable agent loops across documents, tools, and systems
• Work with core agent primitives like MCP, skills, AGENTS.md, shell, and apply patch
• Run agents safely in controlled sandbox environments with the files, dependencies, and tools they need
