May 2026 brought sharper tooling for planning, reviewing, and managing your work with GitHub Copilot in Visual Studio 2026.
Highlights Here’s what’s new for all GitHub Copilot users in Visual Studio 2026. Check the Insiders channel for the latest:
Plan before you build with the Plan agent: The new** Plan agent**(labeled** Plan**in the agent picker) lets you collaborate with Copilot on an implementation plan before any code is written. Copilot explores your codebase with read-only tools, asks clarifying questions, and drafts a detailed plan saved as a markdown file at.copilot/plans/plan-{title}.md
. When you’re ready, clickImplement plan to hand it off toAgent mode.View and manage agent skills: A new** Skillspanel in the chat window lists every agent skill discovered from your workspace and user profile. You can edit a skill, open its file location, or search across skills by name or keyword, all from a single place.Multi-file summary diff for Copilot changes: After Copilot edits multiple files, click Open change summary viewin the working set to see all changes in one tab. Accept or undo at the all-files, per-file, or per-chunk level, with controls to collapse files or step through diff chunks.Manage context window usage: A new ring icon at the top right of the Copilot Chat prompt shows how much of the context window you’ve used. Click to see a detailed breakdown and useSummarize conversation** to compact earlier turns and free up space.Add commit to Copilot Chat: Right-click a commit in** Git History**,** File History**, or the** Annotate (Blame)view and attach it directly as context in Copilot Chat. Multi-select is supported, so you can attach several commits at once.Commit message instructions moved: Commit message custom instructions now live in your repository’s Copilot custom instructions file instead of the old GitHub > Copilot > Source Control Integrationsetting, keeping all Copilot guidance in one place. Improved optimizations for iterative C++ builds**: When**@BuildPerfCpp** detects a regression in full rebuild analysis, it now reruns a comparable incremental build. This better reflects the day-to-day gains from optimizations such as precompiled headers and header refactoring, which can look slower in rebuilds.
