This server has a single tool 'execute_skill_action' with critical definition gaps. The tool description is present but extremely vague (47 chars, below the 50-char minimum for actionable guidance). No input schema is visible in the source code, the mcp_server.py only prints a JSON status message with a tool list, not actual tool definitions with parameters. The client.py demonstrates schema resolution for OTHER gateways (postgres-mcp, github-mcp) but does not define the schema for execute_skill_action itself. Without visible input/output schemas, parameter descriptions, or error handling, this tool cannot be reliably invoked by an LLM. The tool name 'execute_skill_action' is also generic and does not follow verb_noun conventions (e.g., 'invoke_skill', 'run_skill_action').

• Define the input schema for execute_skill_action with explicit parameter types, descriptions, and constraints. Example: {"skill_name": {"type": "string", "description": "Name of the skill to execute (e.g., 'query_database', 'send_notification')"}, "parameters": {"type": "object", "description": "Skill-specific parameters as key-value pairs"}}.
• Expand the tool description to 100-200 characters explaining: (1) what the tool does, (2) when to use it vs other federation tools, (3) what it returns. Example: 'Execute a skill action on a federated MCP gateway. Use this to invoke remote skills (database queries, notifications, etc.) across connected gateways. Returns the skill result or an error with recovery hints.'
• Add per-parameter descriptions. For each parameter (skill_name, parameters, gateway, etc.), explain its type, valid values, and constraints. Use enums for known skill names or gateway identifiers.
• Document the output schema with typed fields. Example: {"success": boolean, "result": object, "error": string, "gateway_latency_ms": number, "skill_name": string}.
• Implement error handling that returns actionable messages. Example: 'Skill "query_database" not found on gateway "postgres-mcp". Available skills: [list]. Try a different skill or gateway.' Include retry guidance for transient failures.
