Critical gaps across all dimensions. Tool names lack action verbs (cmd_meta, cmd_density, cmd_jsonld are script-style, not agent-friendly). Descriptions exist but are generic and lack WHEN/WHY guidance. Input schemas visible for SEO tools but severely incomplete: missing type definitions for most parameters, no enums for constrained inputs. HTTP endpoints (GET /, POST /convert) have descriptions but no formal input schemas visible in source. Output schemas entirely undocumented. No error handling guidance. Security concerns: POST /shutdown is destructive with no confirmation pattern. Overall, this reads as a collection of CLI scripts wrapped minimally for MCP, not a production-grade agent toolkit.

• Rename all tools to verb_noun format: 'extract_meta_tags', 'analyze_keyword_density', 'validate_jsonld', 'convert_image_to_svg', 'generate_svg_archive', 'export_conversion_results'. This enables LLMs to infer intent from the name alone.
• Document complete input schemas for all tools. For POST /convert, explicitly define enums for 'mode' (contour|mosaic), 'engine' (auto|vtracer|native), 'shape', 'vtracer_preset', 'vtracer_mode'. Add min/max for numeric params (colors 1-256, smooth 0-1, etc.).
• Add output schema documentation to every tool. E.g., cmd_meta returns {title, title_len, description, canonical, og_tags, twitter_tags, headings[], imgs[]}. POST /convert returns {svg_data, width, height, colors_used, processing_time_ms}.
• Implement confirmation pattern for POST /shutdown: require a 'confirm=true' parameter and document that this is a destructive operation. Better: remove shutdown from agent tools entirely and manage server lifecycle separately.
• Add error handling guidance to descriptions. E.g., 'If file not found, returns error code 404 with message. Retry with a valid file path or use stdin.' For POST /convert, document timeout behavior and what happens if vtracer is unavailable.
