    Disambiguation5/5

    With only one tool, there is no possible confusion between overlapping functions. The single tool has a clear, distinct purpose.

    Naming Consistency5/5

    The single tool name 'deep-research' is lowercase hyphens, consistent and descriptive of the action. There are no other names to conflict.

    Tool Count3/5

    One tool is quite thin for a deep research capability, though the tool explicitly says it conducts multi-round research internally, making a single entry point feasible. It borders between too few and acceptable for a narrow scope.

    Completeness4/5

    The tool covers the full research workflow in one call, including multi-round searching. Minor gaps exist around controlling research depth, output formats, or retrieving past research, but the core purpose is served.
