Server has 4 tools with basic schemas and descriptions, but significant quality gaps. All tools have descriptions (10-50 chars, below the 50-200 char baseline for LLM optimization). Schemas are present but minimal: search_tickets and analyze_ticket_trends have only a 'query' string parameter with no constraints; list_tickets has limit/offset but no ranges or defaults; get_ticket_summary has empty properties. No output schemas documented. No error handling guidance. No parameter validation rules. Tool names follow verb_noun pattern (positive), but descriptions are too terse to guide LLM selection. No tool annotations (readOnlyHint, etc.). Composition is reasonable (each tool has one responsibility), but lack of detail makes this a D-tier server.

• Expand tool descriptions to 50-200 characters. For search_tickets: 'Search tickets by keyword, status, assignee, or date range. Use this to find specific tickets; use list_tickets for browsing all tickets with pagination.' This clarifies intent and distinguishes it from list_tickets.
• Document output schemas for all tools. E.g., search_tickets should return: {tickets: [{ticket_id, title, status, assignee, created_at}], total_count, next_cursor}. This enables chaining and field extraction.
• Add constraints to list_tickets: limit (integer, 1-100, default 20), offset (integer, >=0, default 0). Include a note: 'Returns paginated results; use offset to fetch subsequent pages.'
• Add format guidance to query parameters. E.g., search_tickets query: 'Free-text search or field:value syntax (e.g., status:open assignee:[email protected]). Supports AND, OR, NOT operators.' Provide 2-3 valid examples in the description.
• Add error handling guidance. E.g., 'If no tickets found, try broadening the query or use list_tickets to see all available tickets. If the query is malformed, the tool returns a validation error with the expected format.'
