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, below the 20-char minimum). The mcp_server.py file contains only a stub that prints JSON and exits, it does not implement the MCP protocol at all. No tool registration, no schema validation, no error handling. The client.py and example_usage.py files show a hardcoded mock implementation, not a real MCP server. This is not a functional MCP server.

• Add a complete JSON Schema for execute_skill_action input parameters. Include type, description, and constraints for each parameter (e.g., error_stacktrace: string, source_repo_context: string, etc.).
• Expand tool description to 50 - 200 characters. Example: 'Analyze a stack trace and source code context to identify root causes and generate a verified patch. Returns root cause analysis, synthesized diff, and verification status.'
• Add parameter descriptions. For each input param, explain what it controls, expected format, and constraints. E.g., 'error_stacktrace (string, required): Full stack trace or error message to analyze.'
• Implement the actual MCP protocol in mcp_server.py. Use a proper MCP library (e.g., mcp-python) or implement the JSON-RPC 2.0 message loop with tool registration, request handling, and structured responses.
• Rename tool to be more specific. Consider 'analyze_error_and_generate_patch', 'debug_error_with_patch_synthesis', or 'orchestrate_debug_session' to clarify intent.
