Critical failures across all dimensions. The single tool 'execute_skill_action' has a minimal description (89 chars, below the 194-char baseline), lacks output schema documentation, and the server implementation is non-functional stub code. The mcp_server.py file does not implement the MCP protocol, it merely prints a JSON status message and exits. No actual tool invocation, parameter validation, error handling, or response formatting is present. Tool definitions appear inferred rather than explicitly registered via proper MCP mechanisms.

• Implement a proper MCP server that listens for tool calls, parses requests, invokes the client logic, and returns structured responses. Use a library like mcp-python or implement the JSON-RPC 2.0 message loop manually.
• Document the complete output schema for execute_skill_action, including all fields (inspection_certificate_id, car_reg, odometer_verified_genuine, points_inspected, fixed_no_haggle_price_inr, money_back_guarantee_days, comprehensive_warranty_years, free_home_test_drive_available) with types and descriptions.
• Expand tool description to 150 - 250 characters explaining: what the tool does (generates 200-point vehicle inspection reports), when to use it (when a user wants a transparent pricing quote for a used car), and what it returns (a certificate with price and warranty details).
• Add validation and error handling: reject invalid car_reg_number formats, validate odometer_reading_km >= 0, and return actionable errors like 'Invalid registration format. Expected format: XX##XX####' instead of silent failures.
• Add parameter constraints: document car_reg_number format (e.g., Indian registration pattern), odometer_reading_km range (0 - 500000), and include examples in descriptions (not as free-form text, but as enum/pattern constraints in the schema).
