Each tool has a clearly distinct purpose: add performs arithmetic, cache handles key-value storage, echo returns input with optional transformation, and status provides server metadata. There is no overlap or ambiguity between these functions.

All tool names follow a consistent, simple verb-based pattern (add, cache, echo, status) without mixing conventions like snake_case or camelCase. This uniformity makes the set predictable and easy to understand.

With 4 tools, the count is reasonable for a template server, covering basic utilities like arithmetic, caching, echoing, and status checks. It's slightly minimal but well-scoped for demonstration purposes, lacking only minor expansions.

As a template server, it covers fundamental operations but has notable gaps for a more robust utility set, such as missing tools for deletion, advanced caching operations, or error handling. However, it provides a complete basic workflow for its intended scope.
