Each tool targets a distinct concept: official BCV rate, P2P market reference, amount conversion, and the percentage gap between them. The `convertir` tool's `fuente` parameter could superficially be confused with `tasa_bcv`/`tasa_p2p`, but the descriptions make clear it performs conversion rather than rate lookup. No two tools do the same thing.

All names are lowercase snake_case, which is consistent, but the grammatical style is mixed: `tasa_bcv`/`tasa_p2p` are noun phrases, `convertir` is a bare verb, and `brecha_cambiaria` is another noun phrase. It reads fine in Spanish and each name is still self-explanatory, so this is a minor deviation rather than a real inconsistency.

Four tools is a tight, well-scoped surface for a narrow domain (Venezuelan exchange rates). Every tool earns its place: two rate sources, one conversion utility, one derived metric, with no redundant or filler entries.

The surface covers the core lifecycle: fetch official rate, fetch market rate, convert between all four currencies, and compute the gap. The main gap is historical/time-series data (no date parameter), so an agent cannot retrieve past rates, but all current-state workflows are covered.
