Solid foundation with all 11 tools properly registered, named with action verbs, and equipped with descriptions and input schemas. However, parameter descriptions are minimal (often single phrases like 'The ticket ID'), output schemas are not formally documented, and error handling lacks recovery guidance. Naming is clear (create_ticket, list_tickets, update_ticket) but some tools like 'deflect' and 'suggest_reply' are vague about their purpose. No enum constraints on priority/status fields despite known valid values. Descriptions average ~60 chars, below the 194-char baseline for A+ tools. Missing documentation of output structure and chaining IDs.

• Add enum constraints to priority, status, and category parameters. E.g. priority: {type: 'string', enum: ['low', 'medium', 'high', 'urgent'], description: 'Ticket priority (low, medium, high, urgent)'}.
• Expand parameter descriptions to 50 - 100 chars each. Include valid values, constraints, and when to use. E.g. 'Filter by ticket status (open, in_progress, resolved, closed). Omit to return all statuses.'
• Document output schemas in tool descriptions or as structured comments. E.g. 'Returns {id: string, title: string, status: string, priority: string, sla_due_at: string}'.
• Enhance error messages with recovery guidance. E.g. 'Ticket ABC123 not found. Call list_tickets() to see available tickets, or check the ticket ID spelling.'
• Rename 'deflect' to 'suggest_kb_before_ticket' and 'suggest_reply' to 'draft_reply' for clarity. Ensure tool names alone convey intent.
