Each tool has a clearly distinct purpose: two conversion tools reverse directions, and the two utility tools check installation and list formats. No ambiguity exists between any pair.

All tool names use lowercase snake_case with a consistent pattern: convert_markdown_to_word and convert_word_to_markdown follow verb_noun structure, while check_pandoc_installation and list_supported_formats are clear imperative verbs. The naming is uniform and predictable.

Four tools is well-scoped for a document converter server, covering both directions of conversion plus necessary utilities. The count is within the ideal 3-15 range and each tool earns its place.

The core conversion lifecycle (Markdown <-> Word) is fully covered, and the utility tools support setup and exploration. A minor gap is the lack of a generic conversion tool for other pandoc formats, but the server's explicit focus on Markdown and Word makes this acceptable.
