Critical gaps across all dimensions. Tool definitions exist in ToolRole.swift but lack visible input/output schemas, parameter descriptions, and detailed docstrings. No evidence of JSON Schema definitions, parameter type constraints, or error handling guidance. Descriptions are minimal (10-30 chars) and do not explain WHEN to use each tool or WHAT it returns. No pagination, no output field documentation, no recovery guidance for errors. Transport mechanism unknown (likely STDIO given Swift/iOS context). This server is not production-ready for agent integration.

• Add complete JSON Schema definitions for all 16 tools. Each tool must declare inputSchema with type, properties, required array, and per-parameter descriptions. Example: {"type": "object", "properties": {"operator_id": {"type": "string", "description": "Unique operator identifier (UUID format)"}}, "required": ["operator_id"]}
• Expand all tool descriptions to 50-200 characters. Include: (1) what the tool does, (2) when to use it vs similar tools, (3) what it returns. Example: 'Check the current balance for a patron account. Returns balance in credits, last updated timestamp, and account status. Use this before purchase_credits to verify available funds.'
• Document output schemas for all read-only tools (operator_status, check_balance, check_payment, session_status, service_status, account_statement, account_statement_infographic, get_pricing_model). Specify field names, types, and what each field represents.
• Add error handling guidance to all write tools. For each tool, document: (1) common failure modes (e.g., 'Operator not found', 'Insufficient credits'), (2) whether the error is retryable, (3) recovery steps (e.g., 'Call register_operator first'). Use structured error responses with error_code, message, and recovery_hint.
• Implement confirmation/dry-run for destructive operations. Add an optional 'confirm' parameter (default false) to certify_credits, purchase_credits, restore_credits, forget_credentials, receive_credentials. When false, return a preview of what would happen; when true, execute. This prevents accidental data loss.
