    A3.8/5.0

    Scored across 32 tools

    Disambiguation3/5

    The mailbox_ and sending_ prefixes plus mostly distinct resource/action pairs make the surface navigable, but several tools are easy to confuse: get_message/list_body/list_content, get_attachment/read_attachment, and the two upload-attachment variants have overlapping boundaries. An agent would need to read descriptions carefully to avoid selecting the wrong one for a content-heavy task.

    Naming Consistency5/5

    All tools follow a consistent snake_case prefix_verb_noun pattern, with mailbox_ and sending_ clearly separating the two API domains. Names like sending_create_attachment_upload are verbose but still predictable and consistent with the rest of the set.

    Tool Count2/5

    With 32 tools, this exceeds the comfortable range and pushes into the too-heavy zone. Many tools could be consolidated, especially the multiple body/content/attachment retrieval variants, even though the split between mailbox and sending operations is logical.

    Completeness4/5

    The set provides strong end-to-end coverage for email: message retrieval, search, threads, folders, attachments, mutation, and both single and batch sending. Minor gaps such as no folder creation/deletion or attachment cleanup prevent a perfect score, but agents should not hit dead ends in normal email workflows.
