Critical failures across all dimensions. The single tool 'execute_skill_action' has a minimal description (47 chars, below the 10-1024 baseline), lacks output schema documentation, and the tool definition itself is not explicitly registered in the MCP server code. The mcp_server.py file contains only a hardcoded JSON response with no actual tool registration, schema validation, or parameter handling. No error handling, no input validation, no security controls. The implementation is a stub that does not implement the MCP protocol.

• Implement proper MCP tool registration in mcp_server.py using the MCP SDK. Define tools with explicit schemas, descriptions, and handlers, not hardcoded JSON responses.
• Expand tool description to 100-200 characters explaining: (1) what autonomous actions it executes, (2) when to call it (e.g., 'for Enterprise customers with billing/webhook issues'), (3) what it returns (resolution state, confidence score, markdown response).
• Add enum constraint to 'customer_tier' parameter: ['Enterprise', 'Standard', 'Basic'] with description 'Customer service tier determining resolution priority and available actions.'
• Document the complete output schema with typed fields: resolution_state (enum: RESOLVED_AUTONOMOUSLY, ESCALATED, FAILED), executed_action (string), customer_response_markdown (string), confidence_score (number 0-1).
• Add error handling: document failure modes (e.g., 'Ticket not found', 'Unable to execute action'), classify as retryable or user-fixable, and provide recovery guidance (e.g., 'Try with a different customer_tier or escalate to human support').
