Scored across 2 tools
Each tool has a clearly distinct purpose: one retrieves a specific area code given a prefecture, the other lists all area codes. No ambiguity or overlap exists.
Both tools follow a consistent verb-areacode pattern using lowercase with hyphens (find-areacode, list-areacode), making them predictable and easy to interpret.
With only two tools, the scope is narrow but appropriate for a read-only area code lookup service. It could potentially include a reverse lookup, but the count is reasonable for the stated purpose.
The tool set covers the essential operations for area codes: querying a specific prefecture and listing all. A minor gap is the lack of a search-by-code function, but the basic use cases are addressed.
