Server has 4 tools with minimal quality. Tool names are verb-based (count_, get_, create_, get_) but descriptions are sparse or missing parameter details. Only create_markdown_file has a structured schema with typed parameters; others have empty input objects. No output schemas documented. Error handling is minimal, create_markdown_file returns success/error objects, but others return raw data without guidance. No pagination, no per-item error reporting, no idempotency hints. Descriptions are in Chinese, limiting LLM comprehension in English-first environments. get_all_markdown_contents returns unbounded results (all .md files) without pagination or limits, risking context window exhaustion.

• Add input schemas to count_markdown_files and get_downloads_files. Even if they take no parameters, declare 'input: {}' with a description explaining they require no arguments.
• Implement pagination for get_all_markdown_contents: add 'limit' (default 20, max 100) and 'offset' parameters. Return {files: [...], total: N, has_more: bool}.
• Document output schemas for all tools. E.g., count_markdown_files returns {count: integer}, get_all_markdown_contents returns {files: [{file: string, content: string, error?: string}], total: integer}.
• Translate all descriptions to English or provide English alongside Chinese. LLMs trained primarily on English will struggle with Chinese-only descriptions.
• Add path traversal validation to create_markdown_file: reject filenames containing '..' or absolute paths. Return clear error: 'Invalid filename: must not contain .. or /. Use relative paths only.'
