Single tool 'execute_skill_action' has critical definition gaps. Description is vague (79 chars, below 100-char minimum for clarity) and does not explain WHAT the tool does, WHEN to use it, or WHAT it returns. Input schema exists but parameter 'query_payload' lacks actionable description, it is a free-form string with no format, length, or content constraints. No output schema is documented; the hardcoded response '"status": "SUCCESS"' is not formally specified. Tool name uses 'execute' (generic verb) rather than domain-specific action like 'generate_wireframe' or 'synthesize_layout'. No error handling guidance, no examples of valid payloads, no indication of idempotency or side effects. The client.py and example_usage.py files show the tool should generate wireframe layouts, but this intent is completely absent from the MCP tool definition itself.

• Rename tool to 'generate_responsive_wireframe' or 'synthesize_component_layout' to match the domain action shown in client.py. Use verb_noun pattern.
• Expand tool description to 100-200 chars: 'Generate a responsive wireframe component tree for a given UI description and viewport width. Returns a structured layout with component hierarchy, grid configuration, and canvas JSON URL. Use this to create design mockups from natural language prompts.'
• Replace 'query_payload' parameter with two explicit parameters: 'prompt_description' (string, 10-500 chars, e.g. 'SaaS analytics dashboard') and 'viewport_width_px' (integer, 320-2560, e.g. 1440). Add descriptions for each.
• Document output schema with typed fields: wireframe_id (string), viewport_mode (enum: DESKTOP|MOBILE|TABLET), component_tree (array of objects with type, flex, items/children), auto_layout_padding_px (integer), wireframe_canvas_json_url (string, URL format).
• Add error handling: specify which inputs are invalid (e.g. 'viewport_width_px must be 320-2560'), whether the operation is idempotent, and what to do if generation fails (retry guidance, fallback options).
