Resolves the full extends chain and returns the merged compiler options that actually apply to a given tsconfig.json. Shows the inheritance chain, all merged options (with enums as readable strings, not magic numbers), and include/exclude patterns.
resolve_module_alias
Maps a TypeScript path alias (e.g. @/hooks/useAuth) to its physical file location on disk, using the resolved paths and baseUrl from the tsconfig. Returns all existing candidates with extension probing.
analyze_project_references
Inspects the references array in a root tsconfig.json and validates that each referenced package has composite: true. Catches broken cross-package dependencies in TypeScript monorepos before they cause silent build failures.
