GitHub Copilot in VS Code August releases: portable plugins, Claude provider switching
GitHub
GitHub's Aug 31 changelog entry rounds up Copilot in VS Code v1.132–v1.135: support for portable plugins following the Agent Plugins 1.0 standard, an experimental Agents window without GitHub sign-in (Claude via API key), switching between Anthropic and Copilot model providers mid-session, resuming sessions created in other apps with multiple windows connected via Agent Host, `/btw` side chats sharing the primary chat's context and prompt cache, and multi-language on-device dictation.
Why it matters
VS Code now treats Claude as a first-class peer provider inside Copilot's UI rather than a rival to be excluded — a notable interoperability shift for the editor with the largest AI-assist install base.
