The tools are mostly distinct: evaluate handles single requests, evaluate_batch handles groups, get_decision reads persisted results, and capabilities reports configuration. There is minor potential confusion between evaluate and evaluate_batch, but the descriptions clarify the difference.

Most tools follow an omnia_<verb>_<object> pattern, but omnia_capabilities is a bare noun and omnia_evaluate lacks an object, breaking the otherwise consistent style. All names share the omnia_ prefix and snake_case, so the inconsistency is moderate rather than chaotic.

Four tools is a well-scoped size for this server's purpose. Each tool covers a distinct operation—single evaluation, batch evaluation, reading decisions, and capability reporting—without unnecessary bloat.

The surface covers the core evaluation lifecycle: evaluate single, evaluate batch, and read persisted decisions, plus capability discovery. A listing or search over persisted decisions would round it out, but the existing tools support the primary workflow without dead ends.
