Critical failures across all dimensions. The single tool 'execute_skill_action' has no visible input schema, no parameter descriptions, and a trivial 47-character description. The MCP server implementation is non-functional: it only prints a JSON status message and exits; it does not implement the MCP protocol at all. No tool registration, no request/response handling, no schema validation. The codebase shows a client class and example usage but zero MCP server mechanics.

• Implement a proper MCP server: add a request/response loop that handles ListTools, CallTool, and other MCP messages. Use the official MCP SDK for Python (mcp package) or implement the JSON-RPC 2.0 protocol correctly.
• Define a complete input schema for execute_skill_action with required parameters (e.g., test_scenario_description: string, target_platform: enum[browser|mobile]), type definitions, and per-parameter descriptions.
• Expand the tool description to 100-200 characters explaining: (1) what it does (generates E2E test steps from natural language), (2) when to use it (when user describes a test scenario), (3) what it returns (array of test steps and CLI command).
• Document the output schema explicitly: return type is object with fields 'generated_test_steps' (array of step objects), 'cli_command' (string), 'estimated_run_time_seconds' (number). Include field descriptions.
• Add error handling: if test_scenario_description is empty, return a clear error like 'test_scenario_description is required and must be non-empty'. If target_platform is invalid, return 'Invalid platform: got "X", must be one of: browser, mobile'.
