In the VS Code ecosystem, these powerful capabilities are available through our C/C++ and CMake Tools extensions.With the latest updates to GitHub Copilot in VS Code, we're bringing the same C++-specific intelligence directly into agent mode by surfacing key language and build system capabilities as tools the agent can invoke.
