Critical failures across all dimensions. The single tool 'execute_skill_action' has no visible input schema, no parameter descriptions, and a generic 1-line description (26 chars). The mcp_server.py file contains only a hardcoded JSON startup message with no actual MCP protocol implementation, no tool registration, no schema definitions, no request/response handling. The 'client.py' file is a standalone utility unrelated to MCP protocol. No evidence of proper tool definition, parameter validation, or error handling. This is a non-functional MCP server stub.

• Define a complete JSON Schema for execute_skill_action input parameters with type, description, and constraints for each field (e.g., skill_name: string, action_type: enum, context: object).
• Expand tool description to 50-150 characters explaining WHAT it does, WHEN to use it, and WHAT it returns. Example: 'Execute a skill action through the MCP gateway, optimizing token usage by filtering relevant tools. Returns execution result with token savings metrics.'
• Implement actual MCP protocol handling in mcp_server.py: parse JSON-RPC requests, dispatch to tool handlers, return structured responses with proper error messages.
• Add parameter descriptions for all inputs (e.g., 'skill_name: The name of the skill to execute (string, required)', 'action_type: The type of action (enum: read, write, analyze)').
• Document the output schema with all returned fields, their types, and meanings. Include token savings, execution status, and any error recovery guidance.
