Scored across 13 tools
Each tool serves a unique purpose: broadcasting vs single messaging, distinct media types for sends, separate info queries, and webhook management. No overlap.
All tools follow a consistent verb_noun pattern in snake_case, e.g., send_message, get_account_info, set_webhook.
With 13 tools, the set is well-scoped for a Viber bot, covering essential operations without excess.
Covers key bot operations: sends, broadcasts, user info, webhooks. Minor gaps like interactive keyboards exist but not critical.
