Plugins gain a new "native" execution environment alongside the existing same-thread one
Claude Code plugins run inside an execution environment. Previously there was one kind, running on the same thread as the app. Now there's a second kind called native, which runs on a native host process instead. Alongside it, a new ui.resolve remote call lets code wait for an environment's UI element tables to finish resolving, with a timeout so it doesn't hang forever.
This expands where and how plugin code can execute, likely to support plugins that need to run outside the main app thread. The ui.resolve addition builds on the existing ui.resolve hook point, which was previously noted as one of the events a plugin module may hook into.
The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

The finding doesn't say what kinds of plugins or use cases the native environment is meant to support.
Anthropic's documentation has since written up native, on Use Claude Code in VS Code.
