Why You Need This
How this feature boosts your daily productivity
Monaco's sandboxed TypeScript worker can't read your `node_modules`, your `tsconfig.json`, or your `*.d.ts` files — so it spends all day flagging fake errors on every CSS module import, every JSX element, and every "react/jsx-runtime" import. Code Intelligence solves this by spawning a real language server (typescript-language-server, gopls, pyright, rust-analyzer, clangd, solargraph, intelephense, or sourcekit-lsp) per project you explicitly opt into. The engine reads your actual `tsconfig.json`, `node_modules`, and type declarations, so the squiggles you see are real and the false positives finally go away. Right-click any project in the sidebar and pick "Enable Code Intelligence…" — a dialog scans your project, lists every detected language with file counts ("55 TypeScript files") and the installed engine version, and lets you turn on the ones you want. Engines only spawn for projects you enable, so memory cost is bounded by your choice (200–500 MB per engine) instead of automatic background spawning. A green brain icon in the status bar shows every active project with a per-project Disable button as the emergency-stop UI for freeing RAM in one click. Eight languages out of the box: TypeScript / JavaScript, Python, Go, Rust, C / C++, Ruby, PHP, and Swift — all detected automatically by file extension. The choice persists across app restarts, so engines respawn next launch without you re-enabling them.
