GitHub Copilot in Visual Studio — May Update
Visual Studio's May update introduces capabilities that expand Copilot's orchestration toolkit. The Plan agent lets you preview and refine a proposed plan before execution. A new skills panel surfaces available agent skills (packaged workflows) for quick discovery. Multi-file diff summaries turn large refactors into reviewable changesets. And context-window management controls help you stay within token limits on extended sessions.
The Plan agent in Visual Studio
The Plan agent generates a proposed solution to your request without executing it. You review the plan, ask follow-up questions, and either approve execution or ask for revisions. This is valuable for high-risk work (refactoring core systems, security patches) where you want human oversight before the agent makes changes.
Skills panel for workflow discovery
A new panel in the Visual Studio sidebar lists available agent skills — packaged workflows your organization has defined. Skills might be "run linter," "apply PR template," or "deploy to staging." The panel lets you browse, filter, and invoke skills without memorizing their names or parameters.
Multi-file diffs and summaries
When an agent modifies hundreds of files, reviewing the changes becomes harder. The multi-file diff summary feature addresses this by generating a structural summary: which files were touched, what changed in each category (tests, documentation, source), and whether the overall changeset passes static checks. You get an intuitive "accept" / "undo" control for the entire changeset instead of line-by-line review.
This is not a replacement for detailed code review. Rather, it is a triage layer that lets you quickly accept safe refactors and focus detailed review on riskier changes.
Context-window management
Extended agent sessions can hit token limits, especially when working with large codebases or long conversation histories. Visual Studio's May update includes controls to monitor and manage context usage: seeing how many tokens remain, compressing earlier conversation history, or starting a new session when limits approach.
