TDQS
Scored across 12 tools
Each specific tool targets a distinct resource and action (campaigns, content, scheduling, sending, reports, templates, members). The meta-tools 'search' and 'execute' are clearly differentiated as discovery and fallback execution, so there is no practical confusion.
Most tools follow a consistent verb_noun pattern (list_audiences, create_campaign, get_campaign_report). The exceptions are the bare verbs 'search' and 'execute', which are minor deviations but still clear in intent.
Twelve tools is well within the ideal 3-15 range. Each tool covers a distinct part of the Mailchimp workflow without redundancy or bloat.
The core campaign lifecycle (create, content, schedule, send, report) and audience/member management are covered. The 'search' and 'execute' meta-tools ensure no Mailchimp API endpoint is unreachable, effectively filling any gaps.
