Each tool targets a clearly distinct purpose: top_items returns rankings, recent_scrobbles returns a listening stream, artist_history checks a specific artist, and rediscovery_candidates surfaces overlooked artists. There is little risk of an agent selecting the wrong tool for a given task.

All four tool names follow the same lowercase snake_case noun-phrase pattern. Though not verb_noun, the convention is perfectly consistent and predictable across the set.

Four tools form a compact, purposeful set for a niche Last.fm listening-history server. Each tool earns its place and the scope feels appropriately focused rather than bloated or thin.

The set covers the core Last.fm user-listening workflow: top items, recent activity, specific artist checks, and rediscovery candidates. Minor gaps like user profile info or detailed artist metadata are absent, but agents can still complete meaningful tasks without major dead ends.
