This server has severe definition quality issues. Tool 1 (execute_skill_action) has a generic description and no visible input schema in the source code. Tool 2 (crawl_spa_to_markdown) has a basic description (89 chars, below the 194-char baseline) and a partial schema visible in the prompt but not in the actual source files provided. Neither tool's output schema is documented. The server appears to be a stub implementation, mcp_server.py only prints a JSON status message and does not actually register tools with the MCP protocol. No error handling, no parameter validation, no security considerations visible. The client.py file shows a mock implementation returning hardcoded responses, not a real MCP tool registration.

• Implement proper MCP tool registration in mcp_server.py using the MCP SDK. Each tool must be registered with a name, description (50 - 200 chars), input schema (JSON Schema with types and descriptions for all parameters), and output schema.
• Add comprehensive input schemas for both tools. For crawl_spa_to_markdown: target_url (required, string, URL format), wait_for_selectors (optional, array of strings, default ['main', 'article']). For execute_skill_action: document what parameters it accepts.
• Document output schemas. crawl_spa_to_markdown should return: {crawl_job_id: string, target_url: string, javascript_dom_rendered: boolean, clean_markdown_bytes: number, tables_and_codeblocks_preserved_pct: number, extracted_links_count: number, llm_ready_markdown_url: string}.
• Expand tool descriptions to 100 - 200 chars. Example: 'Crawl a Single Page Application (SPA) and convert its rendered DOM to clean markdown. Waits for specified CSS selectors to appear before rendering. Preserves tables, code blocks, and links. Returns a markdown URL ready for LLM ingestion.'
• Add error handling with recovery guidance. E.g., 'If the URL is unreachable, verify it is publicly accessible. If JavaScript rendering times out, try increasing wait_for_selectors or reducing page complexity. If markdown conversion fails, the page may contain unsupported content.'
