Cursor details Shadow Workspace for background AI code iteration

Cursor has implemented a shadow workspace that lets its AI apply edits in a hidden Electron window and read back lint results without touching the user's editing session. The post outlines the design goals of LSP availability, independence, privacy, concurrency and speed, and explains why copying a TextModel or running separate language servers failed. It also sketches a future kernel-level folder proxy for runnability, noting that macOS and Windows lack a viable FUSE path and that Rust LSP support is currently unavailable.
