This server has critical definition failures. The single tool 'execute_skill_action' has no visible input schema, no parameter descriptions, and a generic 1-line description (18 chars). The mcp_server.py file contains only a JSON status message with no actual MCP protocol implementation, no tool registration, no schema definitions, no request/response handling. The client.py and example_usage.py files show a simulation interface but are not integrated into the MCP server. Tool definitions are inferred from the feature list, not explicitly registered in code. This is a non-functional MCP server stub.

• Implement actual MCP protocol in mcp_server.py: parse JSON-RPC requests from stdin, dispatch to tool handlers, return structured responses with proper error handling.
• Define explicit input schema for execute_skill_action with required parameters (e.g., skill_name, action_type, context), each with type, description, and constraints (enums where applicable).
• Expand tool description to 50 - 150 characters explaining: what the tool does (executes a skill action in the simulator), when to use it (when the agent needs to run a specific role action), and what it returns (simulation results with status and artifacts).
• Document output schema with typed fields: skill_execution_id, status (enum: success|failure|in_progress), result_summary, generated_artifacts (array), error_message (if applicable).
• Integrate client.py simulation logic into the MCP tool handler so execute_skill_action actually invokes the simulator and returns real results, not hardcoded stubs.
