Scored across 5 tools
Most tools have distinct purposes, but send_email and send_simple_email overlap significantly in functionality. send_simple_email is essentially a subset of send_email, which could lead to confusion about when to use each. The configuration tools (get_current_config, get_smtp_configs) and custom config tool (send_email_with_custom_config) are clearly differentiated.
All tool names follow a consistent verb_noun pattern with snake_case, making them predictable and readable. The naming convention is uniform across all five tools, with clear action verbs (get, send) followed by descriptive nouns.
Five tools is well-scoped for an email sending server, covering configuration retrieval, standard email sending, simple email sending, and custom configuration sending. Each tool serves a distinct purpose without unnecessary duplication or bloat.
The toolset covers core email sending workflows comprehensively, including configuration management and flexible sending options. A minor gap exists in lacking tools for managing sent emails (e.g., list_sent_emails, delete_email) or handling email templates, but agents can still accomplish basic email tasks effectively.
