Scored across 6 tools
Each tool has a clear, distinct purpose: memory.get/put for storage, audit.explain for decision lookup, message.read/send for messaging, and spend for payment authorization. There is no overlap or ambiguity; an agent can confidently select the right tool for a task.
Most tools follow a consistent 'domain.verb' pattern (memory.get, memory.put, audit.explain, message.read, message.send), but 'spend' is a lone verb without a domain prefix, creating a minor deviation. The overall style is uniform and readable.
With 6 tools, the surface is well-scoped for the domains covered (memory, messaging, audit, spending). Each tool serves a distinct operational need, and the count is neither sparse nor bloated.
Core operations are covered: memory supports get and put (including replace), messaging supports read and send, audit supports explain (though no list), and spend supports authorization. Minor gaps exist, such as no explicit delete for memory or messages and no audit listing, but these are not critical for the intended workflows.
