Scored across 2 tools
The two tools have clearly distinct purposes: send_sms sends a message, get_sms_status checks delivery status. There is no overlap or ambiguity; the workflow explicitly links them.
Both tools use a consistent verb_noun snake_case pattern (send_sms, get_sms_status). The naming is predictable and easy to understand.
Two tools cover the core send-and-verify workflow, which is focused and appropriate for a minimal SMS server. It is slightly under the typical 3-15 range but each tool earns its place without redundancy.
The surface covers sending an SMS and checking its status, which are the essential operations. Minor gaps exist (e.g., listing sent messages or retrieving full message details), but agents can work around them for the stated purpose.
