Models, Evals, and Raptor Mini with Julia Kasper

VS Code’s Connor breaks down the shift from local, window-bound agents to a more flexible Agent Host Protocol that can keep sessions alive, sync state across machines, and support remote, long-running workflows. He explains how the protocol opens the door to richer orchestration, multi-client experiences, and custom tools built on top of VS Code’s agent ecosystem—while hinting at where agent-powered development is headed next.

Explore VS Code’s new Agents window — a familiar, focused UI that puts agent-first workflows front and center across repos, harnesses, and machines. It centralizes session management with worktrees, integrated previews, diffs, run tasks and PR flows so agents can iterate across projects while you review, customize extensions, and switch to the editor to edit.

Justin and James deep-dive into Autopilot and the evolving VS Code chat UX—why shimmers and collapsed containers declutter conversations, and why the input bar split and new permissions picker matter. Learn how Autopilot (Insiders preview) can auto-approve tools, answer prompts, iterate until a task_complete signal or max retries, and when to use default vs bypass approvals; practical tips for safe, hands-off workflows and feedback.

Discover how VS Code's subagents revolutionize parallel execution and context management. Learn the fundamentals of agent loops and context windows, then dive into how subagents isolate tasks, run simultaneously, and keep your main agent focused. Plus, explore custom agents and model optimization strategies to supercharge your development workflow.

In this episode James sits down with Ben and Peng from the VS Code team to unpack a year of AI evolution inside the editor — from Copilot Free to the new agent sessions UI. They explain the three agent flavors (interactive local, background, cloud), why agent orchestration matters, and how VS Code is reshaping UX so you can run parallel sessions, delegate work, and treat agent outputs like inbox items to triage. Key takeaways: build context in local chats then delegate to background/cloud, harden projects with linting/tests to improve agent reliability, and expect session results to include artifacts beyond code (tests, screenshots, videos). If you want practical tips for embedding agents into your workflow and a peek at where VS Code is headed, this conversation is a must-listen.
