Microsoft has released Visual Studio Code 1.113, a version that puts a strong focus on AI workflows, chat customization, and tighter support for agent-based tools. The update became available on March 25 for Windows, Linux, and macOS, and it arrives as part of Microsoft’s new weekly release rhythm for VS Code.
One of the biggest additions is the new Chat Customizations editor preview. It gives developers a single place to create and manage chat-related settings, including prompt files, custom instructions, custom agents, and agent skills. The editor also includes an embedded code editor with syntax highlighting and validation, and it can generate starter content with AI based on the current project.
MCP Support Expands
Version 1.113 also improves support for Model Context Protocol servers in Copilot CLI and Claude agents. MCP servers registered inside VS Code, including those defined in mcp.json, can now be used by those external agents rather than staying limited to local editor workflows.
Claude integration has also been refined. VS Code now uses the official Claude agent SDK API to list sessions and messages, replacing the older method of reading JSON files from disk. Microsoft says this should reduce sync issues and prevent missing sessions or messages in Claude agent views.
Smarter Subagents and Better Chat Tools
The update also makes multi-agent workflows more capable. Subagents can now call other subagents, which opens the door to more complex multi-step automation while still avoiding runaway recursion.
Chat image handling has been improved as well. Developers can now open any image attachment in a full viewer, whether it came from a screenshot or was generated by an agent during a tool call. In addition, models that support reasoning, such as Claude Sonnet 4.6 and GPT-5.4, now expose a Thinking Effort menu directly in the model picker, making it easier to adjust how much reasoning a model applies to each request.
Interface and Theme Updates
Beyond AI features, VS Code 1.113 includes practical usability improvements. Browser tab management has been refined, making it easier to organize open tabs in the editor. The release also introduces two new default themes, VS Code Light and VS Code Dark, which replace the older Modern themes with a fresher look while keeping the familiar VS Code style.
