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, constraints, or examples. No output schema documented. Tool name uses generic verb 'execute' rather than domain-specific action (e.g., 'cluster_geohash_coordinates'). No error handling guidance. Fails multiple baseline checks: descriptions should be 10 - 1024 chars (this is 97, acceptable length but lacks actionable detail); parameters must have type+description (query_payload has description but no format/constraints); output schema must be documented (missing entirely).

• Rename tool to 'cluster_geohash_coordinates' or 'analyze_spatial_dbscan' to reflect the actual geospatial clustering operation.
• Replace 'query_payload' string parameter with structured parameters: 'coordinates' (array of [lat, lon] pairs), 'eps_km' (float, 0.1 - 100), 'min_samples' (int, 1 - 100). Add descriptions and constraints for each.
• Document output schema explicitly: return object with 'clustering_run_id', 'total_points_analyzed', 'clusters_formed', 'noise_points_count', 'highest_density_centroid', 'cluster_visualization_url'. Include field types and descriptions.
• Expand tool description to 100 - 200 chars: 'Cluster geographic coordinates using DBSCAN algorithm. Accepts latitude/longitude pairs, returns cluster assignments, centroids, and visualization URL. Use this to group nearby locations by spatial density.'
• Add error handling: validate coordinate format (must be [lat, lon] with lat ∈ [-90, 90], lon ∈ [-180, 180]); return actionable errors like 'Invalid coordinate: lat must be between -90 and 90, got 95.2' instead of generic success.
