Scored across 1 tool
With only one tool, there is no possibility of confusion or overlap. The single tool has a clear and specific purpose: sending an SMS.
The tool name 'send_sms' follows a clear verb_noun convention and matches its function. With only one tool, there are no inconsistencies to evaluate.
The server has only one tool, which feels thin for the scope implied by 'smsmanager'. A typical SMS manager would reasonably include more than just sending, such as checking message status or account balance.
The tool surface is severely limited to sending SMS. Missing capabilities like viewing sent messages, checking delivery status, or managing contacts leave obvious gaps for an SMS management server.
