Copilot in Visual Studio: cloud agents, Debugger agent, .claude/skills/ integration
Copilot in VS gains cloud agent sessions, profile-level custom agents, .claude/skills/ loading, and a Debugger agent that reproduces issues at runtime.
GitHub Copilot in Visual Studio shipped four notable changes:
- Cloud agent sessions can be launched directly from Visual Studio
- Custom agent definitions move to user-profile level (portable across projects)
- Skills can live in
.claude/skills/or.agents/skills/ - New Debugger agent reproduces issues against live runtime to validate fixes before suggesting them
Practitioner note
Two structural signals here:
- Microsoft is reading from
.claude/skills/directly. The Anthropic-defined Skills format — originally proprietary — is now a first-class location consumed by a Microsoft IDE. That’s de facto standardization. - The Debugger agent that runs the code to validate fixes is a quietly important pattern. “Verify before assert” was an aspirational principle a year ago; now it’s becoming a default in commercial agent products.
If you maintain custom skills in your repo, you can now share them across Cursor (similar mechanism), Claude Code, and Visual Studio’s Copilot — without re-authoring per IDE.
