Server has 8 tools with complete input schemas and descriptions present. However, descriptions are generic and lack LLM-optimized guidance on WHEN to use each tool or what happens next. Parameter descriptions are minimal (e.g., 'requester_id' and 'assignee_id' in create_ticket lack any guidance on how to obtain these IDs). No output schemas documented. Error handling is absent, no guidance on recovery paths. OAuth tools lack scope documentation. Naming is clear and verb-based, which is a strength. Overall: functional but below production quality.

• Document output schemas for all tools. For get_ticket, specify: returns {id, subject, description, status, priority, requester_id, assignee_id, created_at, updated_at, tags, custom_fields}. For get_tickets, specify pagination response: {tickets: [...], total_count, page, per_page, has_more}.
• Enhance parameter descriptions with dependency hints. E.g., 'requester_id (integer): The Zendesk user ID of the ticket requester. If you only have a name or email, call search_users() first to obtain the ID.'
• Add error recovery guidance to tool descriptions. E.g., 'If ticket not found, try get_tickets() with a search filter. If create_ticket fails with invalid priority, valid values are: low, normal, high, urgent.'
• Document OAuth scopes explicitly. List available scopes (read, write, etc.) and what each grants. Explain default scopes and when to override.
• Rewrite tool descriptions to be LLM-optimized (50-200 chars). Example: 'Retrieve a single ticket by ID. Use this when you have a specific ticket ID; use get_tickets() to search or list. Returns ticket details including status, priority, comments, and attachments.'
