TDQS
Scored across 15 tools
Each tool targets a distinct action/resource: folder lifecycle, email retrieval/search, mailbox mutations, and composing actions do not overlap. Even similar operations like search_emails vs get_recent_emails are separated by explicit filters vs recency.
All tools follow a predictable snake_case verb_noun pattern (list_, create_, rename_, delete_, get_, search_, mark_, move_, send_, reply_, forward_). This consistency makes the toolset easy to navigate.
With 15 tools, the server fully covers folder management and email workflows without padding; each tool corresponds to a meaningful user action. This sits at the upper bound of the ideal range but remains well-scoped.
The toolset covers folder CRUD, email search/read/threading, marking/moving/deleting, and send/reply/forward/draft. Minor gaps like editing or sending existing drafts and explicit attachment handling prevent a perfect score.
