Scored across 29 tools
Each tool targets a distinct resource or action (packages, inbound mail, outbound mail, facilities, rules, etc.) with clear boundaries. Even related tools like add_note and update_action have clearly separated purposes (package notes vs action request notes). There is no overlapping functionality that would cause confusion.
All tool names follow a consistent verb_noun pattern using snake_case (e.g., get_package, list_inbound_mail, send_outbound_mail, update_webhook). The naming style is uniform across all 29 tools, making the API predictable and easy to navigate for an agent.
At 29 tools, the count is above the typical well-scoped range (3-15) but fits the comprehensive domain of mail and package management. Each tool serves a necessary function without redundancy, and the scope justifies the number.
The tool set covers core workflows (create, read, list, request actions) but lacks explicit update and delete operations for several resources like rules, packages, and webhooks. Notable gaps include no update_rule, delete_rule, delete_package, or delete_webhook, which may cause dead ends when agents need to modify or remove resources.
