Each tool has a distinct purpose: health check, listing models, listing formula pointers, retrieving specs, and computing coefficients. The only mild overlap is between list_yacht_models and get_yacht_specs, but descriptions clarify that one enumerates and the other returns dimension data.

Most tools follow a clean verb_noun pattern (list_*, get_*, compute_*). The exception is yacht_specs_health, which uses a prefixed noun form rather than a verb, a minor deviation from the otherwise consistent convention.

Five tools is well-scoped for a bundled local snapshot server. Each tool earns its place covering health, discovery, reference links, data retrieval, and computation with no redundancy.

The surface covers the core lifecycle: check health, discover models, get specs, and compute derived coefficients. Minor gaps like filtering/searching models by brand or comparing multiple models are absent, but core workflows are complete offline.
