Each tool has a clearly distinct role: scanning for inventory, converting one book, batch converting a folder, and checking batch status. The boundary between single and batch conversion is explicit, and status checking is separate from execution.

All names use snake_case and begin with recognizable action-oriented terms. The pattern is mostly verb_object, though convert_book_to_word and batch_convert_folder add extra descriptive segments that slightly break a strict convention.

Four tools is well-scoped for a book conversion server. Each tool earns its place by covering discovery, single conversion, batch conversion, and progress tracking without redundancy.

The surface covers the main lifecycle: scanning inputs, converting a single file, batch converting folders with resume state, and checking batch progress. Minor gaps exist around cancellation, output listing, or conversion option configuration, but core workflows are supported.
