Each tool has a clearly distinct role: search_notes returns snippets, read_note returns full content, list_recent lists recently modified notes, and notes_stats summarizes corpus metadata. The descriptions explicitly clarify boundaries, especially search versus read.

Three tools follow a verb_object pattern (search_notes, read_note, list_recent), while notes_stats is noun_noun. The deviation is minor and still readable, but it breaks strict consistency.

Four tools are well-scoped for a focused notes retrieval server. Each tool earns its place and covers a distinct query pattern without bloat.

The read-only surface covers search, full read, recent listing, and stats, but there are no create, update, append, or delete operations. For a notes server, this is a notable gap if agents are expected to manage notes rather than only inspect them.
