Single tool 'execute_skill_action' has critical definition gaps. Description is present (97 chars) but vague, does not explain WHAT geospatial operations are supported, WHEN to use it, or what the output structure is. Input schema exists but is severely underspecified: 'query_payload' is a bare string with no format guidance, constraints, or examples. No output schema documented. Tool name is generic (execute_skill_action) and does not follow verb_noun pattern (should be something like 'optimize_vehicle_route' or 'calculate_route_distance'). No error handling guidance. No parameter validation rules. The implementation returns a hardcoded success response regardless of input, indicating the tool is non-functional or a stub.

• Rename tool to 'optimize_vehicle_route' or 'calculate_tsp_solution' to clearly signal the action and match the domain (vehicle routing, TSP optimization).
• Replace 'query_payload' string parameter with explicit, typed parameters: depot_coords (array of floats), waypoints (array of objects with id, coords, optional time_window), vehicle_count (integer), etc. Document each parameter's format and constraints.
• Document the output schema: return an object with fields like optimal_sequence (array of waypoint IDs), total_distance_km (float), estimated_time_minutes (integer), turn_by_turn_url (string). Include example response.
• Expand tool description to 150 - 250 chars explaining: 'Optimizes multi-stop vehicle delivery routes using TSP algorithms. Accepts depot location and waypoint coordinates; returns optimal visit sequence, distance, and time estimates. Use when planning delivery routes or logistics optimization.'
• Implement actual TSP optimization logic or clearly document that this is a mock/stub. If real, add error handling for invalid coordinates, unreachable waypoints, and timeout scenarios with recovery guidance.
