Scored across 7 tools
The core transform tools (search, describe, validate, generate, parse) each target a distinct action and are hard to confuse. However, list_families and list_servers both perform catalogue-style listing and could be misselected, and search overlaps with them at the discovery level. The explicit 'When to use / Not for' notes mitigate this, but the boundary between the three listing/discovery tools is not perfectly crisp.
Most names are single imperatives (search, describe, validate, generate, parse) with a consistent snake_case, verb-first pattern for the two listing tools (list_families, list_servers). The mix of bare verbs and verb_noun is a minor deviation but remains predictable and readable.
Seven tools is well-scoped for an ISO 20022 gateway spanning discovery, schema description, validation, generation, and parsing. Each tool earns its place with no redundant entries.
The surface covers the discovery-to-transform lifecycle (search, describe, validate, generate, parse) and documents direction-specific limits. Minor gaps exist—pain/acmt messages have no parser and camt.053 has no generator—but these are intentional, documented, and covered by backing-server XSD validation, so agents are not left at a dead end.
