Scored across 3 tools
Each tool has a distinct purpose: list all entities, read one entity by name, and write an entity. There is no overlap or ambiguity between them.
All tool names follow a consistent verb_noun snake_case pattern: list_entities, read_entity, write_entity. The singular/plural usage is natural and predictable.
Three tools is well-scoped for a focused heat-pump entity server. Each tool serves a clear, necessary function without redundancy.
The set covers listing, reading, and writing configured entities, which is the core workflow. Missing create/delete is acceptable since entities are 'configured' externally, though there is no explicit way to discover which entities are writable.
