convert_to_markdown is essentially a subset of convert, which already lists Markdown among its output formats. An agent must guess whether to use the general tool or the specialized one, and the descriptions don't clarify when to prefer each.
Names mix conventions: list_input_formats follows verb_noun, convert is a bare verb, and convert_to_markdown uses verb_to_target. They are readable but do not form a predictable pattern.
Three tools is reasonable for a focused document-conversion server, covering format discovery and conversion without bloat. It is on the lean side but each tool has a plausible role.
Input format discovery plus flexible conversion covers the core domain well. Minor gaps exist (no output-format enumeration or batch/validation helpers), but agents can work around them.
