list_notes (enumerate/filter), get_note (single note by ID), and search_notes (keyword substring) each target a distinct retrieval pattern, and the descriptions make the boundaries clear. Minor overlap exists because list_notes and search_notes both return paginated note collections, so a broad search can look like a list.

All three tools follow a clean snake_case verb_noun pattern (list_notes, get_note, search_notes). The only deviation is singular 'get_note' versus plural 'list_notes'/'search_notes', which is a conventional single-vs-collection distinction rather than an inconsistency.

Three tools is on the thin side for a note-management domain; it covers only read access. It is not an extreme mismatch, but the surface feels under-scoped for what a sticky-notes server would typically need to be useful.

The set is read-only: there is no create_note, update_note, or delete_note, even though filters like 'include_deleted' and flags like 'is_open' imply write/lifecycle operations exist. An agent asked to add, edit, close, or delete a note would hit a dead end.
