Critical failures across all dimensions. The single tool 'execute_skill_action' has a description (good), but the input schema is severely underspecified: 'proposed_agent_action' is typed as a generic object with no field constraints, and 'risk_level' lacks an enum constraint despite the description explicitly listing valid values (LOW, MEDIUM, HIGH, CRITICAL). No output schema is documented anywhere. The tool definition is inferred from client.py and example_usage.py rather than explicit MCP server registration, the mcp_server.py file is a stub that prints JSON but does not actually implement the MCP protocol. No error handling, no recovery guidance, no parameter validation rules documented. The server does not implement MCP at all, it's a mock that prints a status message and exits.

• Convert 'risk_level' parameter to an enum: {"type": "string", "enum": ["LOW", "MEDIUM", "HIGH", "CRITICAL"], "description": "Risk classification for the proposed action. LOW: minimal blast radius, auto-approved. MEDIUM: 2-3 systems affected, 30s auto-approval. HIGH: 3+ systems or sensitive operations, requires explicit approval. CRITICAL: irreversible or high-impact, requires human review and confirmation token."}
• Define 'proposed_agent_action' schema with required fields and types. Example: {"type": "object", "required": ["action_type", "target_scope"], "properties": {"action_type": {"type": "string", "description": "The type of action (e.g., bulk_email_campaign, database_migration, user_provisioning)"}, "target_scope": {"type": "object", "description": "Scope of the action (e.g., affected users, systems, resources)"}, ...}}
• Document the complete output schema with all fields, types, and descriptions. Include: approval_required (boolean), risk_assessment (string), safe_execution_plan (array of strings), rollback_plan (string), estimated_blast_radius (integer), approval_token_required (boolean if HIGH/CRITICAL).
• Implement actual MCP protocol in mcp_server.py: handle initialize, list_tools, call_tool requests per the MCP spec. The current stub does not accept or process any MCP messages.
• Add error handling with recovery guidance: document what happens if the action fails, what errors are retryable, and what the LLM should do next (e.g., 'Blast radius exceeded threshold. Consider splitting the action into smaller batches.').
