This server has critical definition quality failures across all three tools. All tools use a single generic 'command' string parameter instead of structured, typed inputs. Descriptions are minimal (10-20 chars) and lack context on WHEN to use each tool or what it returns. No output schemas are documented. No error handling guidance. The tool interface does not match the chat data model, users say 'Send a message to Jack' but the tool requires a 'telegram:' prefixed command string, forcing agents to construct low-level protocol strings. All three tools are WRITE operations with no confirmation/dry-run pattern. No input validation, no rate limiting, no audit logging.

• Restructure send_telegram to accept structured parameters: recipient (string, required), message_text (string, required), parse_mode (enum: 'plain'|'markdown'|'html', optional). Remove the 'command' string parameter entirely.
• Restructure send_email to accept: recipient_email (string, required, email format), subject (string, required), body (string, required), body_format (enum: 'plain'|'html', optional). Document that Gmail credentials must be pre-configured server-side.
• Restructure send_whatsapp to accept: recipient_phone (string, required, E.164 format), message_text (string, required). Remove 'command' string parsing.
• Add output schemas: all three tools should return {success: boolean, message_id: string, timestamp: ISO8601, status: 'sent'|'queued'|'failed', error_details?: string}. This enables agents to track delivery and retry with message_id if needed.
• Add error handling: return structured errors like {success: false, error_code: 'INVALID_RECIPIENT', error_message: 'Recipient phone must be E.164 format (e.g. +1234567890)', retryable: true}. Include recovery hints for each error class.
