Critical gaps across all dimensions. Tool definitions lack proper schemas, descriptions are generic or missing, and parameter documentation is absent. Only 1 of 6 tools has a meaningful description (show_ui). Chart, Audio, Document, Video, Image tools have placeholder descriptions ('Tool for X processing') that provide no actionable guidance. No input schemas visible for most tools. Tool names lack action verbs (Chart Tool, Audio Tool, Document Tool, Video Tool, Image Tool are generic). No error handling guidance, no output schema documentation, no parameter constraints. The codebase shows HTTP transport via mcp-handler but tool definitions are severely underdeveloped.

• Rename tools with action verbs: 'show_ui' → 'display_widget', 'Chart Tool' → 'generate_chart', 'Audio Tool' → 'synthesize_audio', 'Document Tool' → 'process_document', 'Video Tool' → 'process_video', 'Image Tool' → 'process_image'.
• Add complete input schemas for all tools. Chart and Audio tools accept 'prompt' parameter, document type (string), length constraints, and examples. Document/Video/Image tools need explicit parameter definitions visible in code.
• Expand descriptions to 50-200 characters. E.g., 'generate_chart: Creates interactive charts from natural language descriptions. Supports bar, line, pie, and scatter plots. Returns chart data and rendering instructions.' instead of 'Retrieves chart data based on the given prompt'.
• Document output schemas for each tool. E.g., generate_chart returns {chart_type, data_points, title, axes}. synthesize_audio returns {audio_url, duration_ms, format}. This enables LLMs to chain tools correctly.
• Add parameter descriptions. For 'prompt' parameters, specify: 'Natural language description of desired output (50-500 chars). Be specific about chart type, data structure, or content format.'
