A3.7/5.0
Scored across 19 tools
Disambiguation5/5
Every tool targets a unique resource-action combination (e.g., missive_get_contact vs missive_list_contacts). There is no overlap in functionality; the purposes are clearly distinct.
Naming Consistency5/5
All tool names follow a strict 'missive_verb_noun' pattern in lowercase snake_case. Verbs are limited to create, get, list, and update, applied consistently across resources.
Tool Count4/5
With 19 tools, the server is slightly above the ideal range (3-15) but still reasonable for covering multiple resources like contacts, conversations, messages, and lists. Each tool serves a specific purpose without unnecessary redundancy.
Completeness4/5
Core workflows are covered: listing, getting, creating contacts/drafts, managing conversations, and viewing sub-items. Minor gaps exist (no update for contacts, no delete for any resource), but these are acceptable for an initial release.
