Return the full Svelte component dependency graph for a project: every component/route node (workspace-relative path id + display label + type + unused flag) and every import link.

Look up a single component or route by its workspace-relative path (e.g. "src/lib/Button.svelte"). Returns its parents (components that import it), children (components it imports), whether it is unused/a route, and its Svelte 5 public API surface: props (name, optional, bindable, rest) and slots.

Return every component that is imported somewhere in the project but rendered nowhere (never referenced in any importer's template). Computed globally, so the result does not depend on file order.

Return every route node (+page/+layout/+error) with its display label and the direct child components it pulls in.

Invalidate all caches for the project and re-parse every file from scratch. Returns a summary with the node and link counts. Use when you want to guarantee fresh results.
