Visual Studio Code (VS Code) has just launched version 1.99, introducing several exciting features that promise to enhance the coding experience. Among the notable updates is the official stabilization of agent mode, which now becomes part of the stable release. This feature integrates GitHub Copilot’s agent mode, enabling developers to leverage natural language to define high-level tasks and trigger autonomous code-editing sessions. With agent mode, Copilot takes charge by planning the necessary work, selecting the appropriate files, and executing code modifications, all while monitoring the outcomes and making iterative improvements.
One of the key advancements in the 1.99 update is the support for Model Context Protocol (MCP) servers in agent mode. MCP serves as a standardized method for AI systems to interact with external applications and data sources. By utilizing this protocol, developers can enhance their AI-driven workflows, allowing Copilot to invoke tools and perform actions such as querying databases, retrieving web data, or managing file operations. This opens up new possibilities for more dynamic and context-aware coding assistance, streamlining the development process.
Another feature that has gained attention is the introduction of Next Edit Suggestions. This improvement offers more compact, readable, and non-intrusive suggestions that blend seamlessly with existing code. The new version also updates the gutter indicator to make these suggestions easier to spot and implement. With these changes, developers can expect a more efficient coding environment where AI-generated suggestions are more intuitive and less disruptive, boosting overall productivity.
Additionally, the update introduces several enhancements to the Copilot experience. AI-powered file edits now come with improved handling of diagnostics events, which are muted when the editor is rewriting files. Developers also gain more control over file-saving actions, as they can now explicitly choose to save files after incorporating AI-generated edits. Syntax highlighting for inline suggestions is now enabled by default, further improving the clarity and ease of use for developers working with Copilot’s intelligent suggestions.
