Each tool has a clearly distinct role: air_quality returns measurements and forecasts for a place, air_stations enumerates monitoring stations in an administrative area, and data_sources explains provenance and caveats. There is no plausible way to confuse these three operations.

All three names use the same snake_case, noun-based convention (air_quality, air_stations, data_sources) with a consistent 'air_'/'data_' domain prefix. The pattern is predictable even though it is resource-oriented rather than verb_noun.

Three tools is on the small side but appropriate for a narrow, read-only Polish air quality service, and each has a distinct purpose. One of the three (data_sources) is metadata/documentation rather than a functional query, leaving only two substantive data tools.

The surface covers the core workflows: point queries for current AQ plus forecast, station discovery for broader areas, and provenance. Gaps are minor for this domain — no historical/time-series query, no per-station detailed reading endpoint, and no bulk multi-location lookup — but agents can work around these via place or region queries.
