Descriptions are present but generic (avg ~40 chars, well below the 194-char baseline). No parameter descriptions exist for most tools. Tool names lack clarity, many are ambiguous (e.g., 'get_scene_info', 'get_graph_info', 'get_node_info' are indistinguishable). Only 1 tool (set_node_comment, connect_nodes, disconnect_nodes, set_parameter, set_graph_output_size, arrange_nodes, execute_python, apply_graph_change) has any visible parameter schema. No output schemas documented. Error handling absent. This server is not production-ready.

• Add complete input schemas to all 39 tools with empty {} schemas. Include parameter types (string, integer, boolean, object), descriptions, and constraints (enums, min/max, patterns). Example: create_graph should require graph_name (string, 1-255 chars), package_id (string), and optional description.
• Expand descriptions to 100-200 chars. Include WHAT the tool does, WHEN to use it, and what it returns. Example: 'Create a new graph in the current package. Returns graph_id and graph_name. Call this after load_package() to add a new procedural texture graph.'
• Document output schemas for all tools. Specify returned fields, types, and whether results are paginated. Example: list_controls returns {controls: [{id: string, name: string, type: string, value: any}], total: integer}.
• Disambiguate similar tool names. Rename get_scene_info → describe_scene_state, get_graph_info → describe_graph_structure, get_node_info → describe_node_properties. Add clarifying descriptions explaining what each reveals.
• Add error handling and recovery guidance to destructive tools. Example for delete_graph: 'Irreversible operation. Returns error if graph has unsaved changes. Suggest user call save_package() first. On failure, offer list_graphs() to show available alternatives.'
