    Disambiguation5/5

    Only one tool exists, so there is no possibility of confusion between tools.

    Naming Consistency5/5

    With a single tool, naming is trivially consistent.

    Tool Count4/5

    One tool for making HTTP requests to localhost is slightly thin but appropriate for a focused utility.

    Completeness4/5

    Covers core HTTP request parameters (method, path, data, headers) but limited to localhost and lacks automatic content-type handling.
