The server provides three well-named tools with complete JSON Schema input definitions and enum-constrained parameters. Tool descriptions are present and substantive (85-95 characters each). However, the server lacks documented output schemas, missing critical fields like return types and structure. Error handling guidance is absent, tools provide no recovery hints. The naming is clear and action-oriented (create_, update_), and parameters are well-typed with descriptions. Security-sensitive operations (WRITE risk) lack confirmation/dry-run patterns. No tool annotations (readOnlyHint/destructiveHint) present despite MCP SDK support. Relative to the rubric baseline of 194-char descriptions, these average ~90 chars, which is lean but acceptable. All parameters are properly typed (no scores capped at 30 for type issues). Overall: solid definition foundation with gaps in output documentation and error recovery.

• Document output schemas for all three tools. Example for create_ticket: 'Returns { ticketId: string, customerId: string, createdAt: string (ISO 8601), status: 'open' }'.
• Add error recovery hints to each tool description. Example: 'If creation fails with status 409 (conflict), the ticket may already exist, call search_ticket() to verify.'
• Add tool annotations to the input schema: { properties: {...}, required: [...], annotations: { io.modelcontextprotocol.destructiveHint: true } } for all three tools.
• Document parameter dependencies in update_ticket. Add to 'resolution' description: 'Only required when status is resolved or closed. Ignored for other statuses.'
• Clarify the initial status when create_ticket is called. Add to tool description: 'The created ticket will have status=open. Update status with update_ticket() as needed.'
• Consider adding pagination support if these tools are expected to return lists (though the current design returns single items, which is correct).

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
