Single tool 'execute_skill_action' has a minimal description (97 chars) that lacks actionable context for LLM selection. Input schema is present but parameter 'query_payload' has only a generic description ('Input execution payload for this skill') with no format, constraints, or examples. No output schema is documented, the tool returns a hardcoded JSON string with no structure definition. No error handling, no parameter validation guidance, and no indication of what 'Multimodal Design & Canvas Synthesis operations' actually entails. The tool name does not follow verb_noun convention (should be something like 'normalize_svg_geometry' or 'synthesize_design'). Tool definition is visible in code but implementation is a stub that always returns success, making it unsuitable for production use.

• Rename tool to a specific action verb: 'normalize_svg_geometry', 'synthesize_design_canvas', or 'transform_vector_svg'. This makes the tool's purpose immediately clear to LLMs.
• Expand tool description to 100-200 chars explaining: (1) What it does (e.g., 'Normalizes SVG vector paths to a standard viewBox and stroke width'), (2) When to use it (e.g., 'Call this to standardize brand icon geometry'), (3) What it returns (e.g., 'Returns normalized SVG path, viewBox, and asset URL').
• Document the 'query_payload' parameter with explicit format: specify if it is a JSON string, SVG path data, or a structured object. Include constraints (max length, required fields) and an example: 'JSON object with keys: svg_path (string), target_viewbox (string, e.g. "0 0 24 24"), target_stroke_width (number, 1-10)'.
• Add an explicit output schema documenting all returned fields: 'normalization_id' (string), 'viewbox' (string), 'normalized_path_d' (string), 'stroke_width' (number), 'stroke_linecap' (string), 'stroke_linejoin' (string), 'vector_minified_bytes' (number), 'svg_asset_url' (string). Include descriptions for each field.
• Implement error handling: return structured errors with actionable guidance. E.g., if SVG path is invalid, return '{"error": "Invalid SVG path syntax", "suggestion": "Ensure path uses valid M, L, H, V, Z commands"}' instead of always returning success.
