The GenPark AI Code Refactoring Lint Fixer server has severe definition quality issues. The single tool 'execute_skill_action' is barely defined in the source code. The mcp_server.py file contains only a stub that prints a JSON status message, it does not actually register tools with the MCP protocol, define schemas, or implement the Model Context Protocol correctly. The tool name is vague (violates verb_noun pattern), no description is visible, no input/output schemas are defined, and no error handling is present. This is a non-functional skeleton, not a production-ready MCP server.

• Rename tool from 'execute_skill_action' to 'refactor_code', clearer verb_noun naming that conveys the action.
• Add comprehensive tool description: 'Analyzes Python code and applies automated refactoring and linting fixes. Returns the refactored code with explanations of changes made. Requires: valid Python code as input. Returns: refactored_code (string), changes (array of change descriptions).'
• Define input schema with typed parameters: { 'code': { 'type': 'string', 'description': 'The Python code to refactor (must be syntactically valid)' }, 'lint_rules': { 'type': 'array', 'items': { 'type': 'string' }, 'description': 'Optional: specific linting rules to apply (e.g., E501, W291). If omitted, applies all enabled rules.' } }
• Define output schema: { 'refactored_code': { 'type': 'string', 'description': 'The refactored Python code' }, 'changes': { 'type': 'array', 'items': { 'type': 'object', 'properties': { 'line': { 'type': 'integer' }, 'change': { 'type': 'string' } } }, 'description': 'List of changes applied, with line numbers and descriptions' }, 'errors': { 'type': 'array', 'items': { 'type': 'string' }, 'description': 'Any linting or syntax errors encountered' } }
• Implement proper MCP protocol in mcp_server.py: read JSON-RPC messages from stdin, handle initialize and tool/call messages, invoke the CodeRefactorClient.refactor_code() method, and return structured JSON-RPC responses.
• Add error handling: if code is not valid Python, return a clear error message: 'Invalid Python syntax at line X: <syntax error detail>. Please fix the syntax and try again.'
