Scored across 26 tools
Every tool has a clear, distinct job: archive/trash/snooze are separated, single-thread vs bulk operations are explicitly contrasted, and unsubscribe-related tools are carefully split by purpose (checking, performing, bulk, sender overview). Algorithm solutions that could overlap, like `modify_labels` vs `bulk_modify`, provide strong usage guidance that prevents misselection.
Tool names primarily follow a verb_noun convention (`list_labels`, `create_filter`, `get_thread`, `bulk_modify`) with clear verbs like list/get/fetch/create. Minor deviations exist (`what_changed`, `triage_digest`, `archive`/`trash`/`snooze`), but they are still readable and do not break the overall predictable style.
At 26 tools, the set is slightly above the typical well-scoped range and crosses the 'heavy' threshold, but the domain is broad enough that most tools earn a place due to distinct single-versus-bulk variants and separate list views. Some consolidation would benefit usability, though the count is not egregiously inflated.
The mail domain is comprehensively covered: read state, archive/trash, labels, filters, snooze, search, bulk operations, subscription lists, and attachment downloads. The main gaps are marginal—direct spam-classification and permanent-delete tools are not explicitly present, while sending/forwarding is an intentionally documented exclusion rather than an accidental omission.
