| ruby_to_jsonA | Parse a Ruby hash or array literal (hashrockets, symbol keys, shorthand syntax, nesting, nil/true/false) and return clean JSON with alphabetically sorted keys. Symbols are rendered as ":name" strings. |

TDQS
Scored across 2 tools
The two tools have clearly distinct purposes: one compares two Ruby hashes and returns a diff, the other converts a Ruby hash/array literal to JSON. There is no overlap or ambiguity.
Both tool names follow a consistent verb_noun snake_case pattern: ruby_hash_diff and ruby_to_json. The prefix 'ruby_' is shared, and the second part describes the action ('hash_diff' vs 'to_json').
With only 2 tools, the server is minimal but still focused. It feels slightly thin for a general utility server, but for a niche Ruby hash utility it is acceptable and not excessive.
The tools cover diffing and conversion, which are useful but there are obvious gaps such as merging, validation, or formatting. The surface is not severely incomplete but lacks typical CRUD lifecycle coverage.
