Server has 7 tools with explicit schemas and descriptions, but quality is inconsistent. Naming follows verb_noun pattern (ping_test, login_library, search_papers, get_paper_detail, persist_paper, download_paper, open_url), good. However, descriptions are domain-specific (Chinese) and lack LLM-optimization guidance. Parameter descriptions exist but many lack type constraints, enums, or validation rules. No output schemas documented. Error handling is minimal, no recovery guidance visible. Security concern: login_library accepts username/password as parameters (anti-pattern; should use server-side injection). Overall: functional but below production baseline.

• Move username/password to server-side environment variables or vault. Accept only university code and optional service URL. Implement OAuth or SSO token refresh internally.
• Document output schemas for all tools. E.g., search_papers returns {results: [{title, url, dxid, authors, year}], total_count, page}. Include field types and descriptions.
• Add enums to search_papers: doc_types should list valid integers (1=journal, 3=thesis, 4=conference, etc.); sort should be enum [0, 1, 2, 3, 4, 6] with labels.
• Enhance error responses with recovery hints. E.g., 'Login failed: invalid credentials. Try login_library with correct university code.' or 'Paper not found. Try search_papers with broader keywords.'
• Expand descriptions to 50-150 chars. E.g., open_url: 'Opens a URL in the user's default browser. Use after search_papers to view full paper details or access download links.'
