Each tool has a clearly distinct role: search_library finds pages by metadata, get_page retrieves a page's body, convert_url adds/saves new content, and list_projects enumerates projects. The search-vs-get boundary is well explained (metadata vs. full markdown), so misselection is unlikely.

All four names follow a strict verb_noun snake_case pattern (search_library, get_page, convert_url, list_projects). No mixing of conventions or vague verbs.

Four tools is a tight, well-scoped set that maps cleanly to the core read/add/project workflows. It leans slightly thin for a library service, but each tool earns its place.

The read and create paths are covered (search, get, convert), but there is no delete/update for saved pages and projects can only be listed, not created or managed. These are notable lifecycle gaps an agent would hit.
