Six tools with basic schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. Tool names follow verb_noun convention (search_papers, get_paper, list_bookmarks, add_bookmark, remove_bookmark, start_review). Descriptions exist but are minimal (10-50 chars), below the 50-200 char baseline for LLM-optimized descriptions. Input schemas present with type declarations, but parameter descriptions are sparse or missing. No documented output schemas. Error handling and recovery guidance absent. Composition is reasonable (single responsibility per tool), but parameter constraints (enums, ranges, formats) are underdeclared.

• Expand tool descriptions to 50-200 chars. Example: 'search_papers: Search academic papers by query string. Returns up to max_results matching papers with title, authors, year, and paper_id. Use this to discover papers before calling get_paper for full details.'
• Document output schemas for all tools. Specify which fields are returned (e.g., search_papers returns [{paper_id, title, authors[], year, abstract}]). Include field types and whether they are always present.
• Add parameter constraints and formats. Example: 'query (string, 1-500 chars, supports AND/OR operators)', 'max_results (integer, 1-100, default 20)', 'num_researchers (integer, 1-10, default 3)'.
• Add error handling guidance. Example: 'If search returns 0 results, try a broader query or use different keywords. If add_bookmark fails with "duplicate", the paper is already bookmarked, call list_bookmarks to verify.'
• Implement confirmation pattern for remove_bookmark. Add a 'confirm' boolean parameter (default false) or a separate 'confirm_remove_bookmark' tool to prevent accidental deletions.
