VS Code 1.133.0

Release Date: August 12, 2026

Visual Studio Code 1.133 is rolling out now — and it's all about keeping your agent sessions connected, your chats scannable, and your previews live. Released August 12, 2026, this iteration sharpens the Copilot/Claude experience and polishes the everyday editor flow.

⚡ Agent Antics — One Session, Many Windows

The headline act: the agent host. VS Code 1.133 can now run agent harnesses in a dedicated process based on the Agent Host Protocol (AHP), letting you connect to the same agent session from multiple VS Code windows at once. Start a long-running agent task in one window, keep an eye on it from another. No more duplicated context, no more lost threads.

🧠 Model Mashup — Anthropic Meets Copilot

Claude sessions get a serious flexibility boost. The model picker now shows both provider groups side by side, so you can switch between Anthropic and Copilot models between turns — no reconfiguring the agent host mid-conversation. Anthropic models bill your API key; Copilot models use your subscription. Pick per turn, pay per provider.

📌 Prompt Pinning — Sticky Scroll for Chat

Long chats just got a lot easier to follow. Prompts you've scrolled past now stay pinned to the top of the conversation, exactly like sticky scroll in the editor. The pinned prompt shows its position in the thread — click it to jump back, or step through prompts with the previous/next buttons. Toggle it via chat.stickyScroll.enabled.

🖼️ Live HTML Loops — Auto-Reload Preview

Static previews are so last year. When a local HTML file is open in the integrated browser, it now refreshes automatically the moment the file changes on disk. Agent edits and your own saves show up instantly. Per-tab toggling plus a default switch via workbench.browser.autoReloadOnFileChange.

🚪 GitHub Gate Gone — Agents Without Sign-In

Experimental but welcome: the Agents window can now open without a GitHub sign-in prompt. Machines that can't reach github.com — or users who just don't interact with GitHub — can run Claude with an existing API key. Flip on chat.agentHost.allowSignedOutWhenUsable. GitHub auth then binds to individual agents and models instead of the whole window.

🧾 Issue Influx — Tracking Wins

Beyond the features, the 1.133 cycle shipped a fresh batch of contributions to both the VS Code codebase and its issue tracking. The usual quality-of-life grind continues.
