Server has 16 tools with basic schemas and descriptions, but significant gaps limit production readiness. All tools have descriptions (10-50 chars, mostly generic), and input schemas are present with type definitions. However, descriptions lack LLM-optimized guidance on WHEN to use each tool, parameter relationships are undocumented, and error handling is absent. Output schemas are not documented. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite clear risk levels. Naming is verb-first and clear, but parameter descriptions are minimal. The server exposes destructive operations (delete_item, write_file) without confirmation patterns or dry-run support.

• Add tool annotations: mark read-only tools with readOnlyHint=true (list_drives, get_home_directory, read_file, search_*), destructive tools with destructiveHint=true (delete_item, write_file), and idempotent tools with idempotentHint=true (create_directory, copy_item).
• Expand descriptions to 100-200 chars with WHEN guidance. E.g., 'List directory contents with optional hidden files. Use this to explore a folder structure; use get_file_details for metadata on a single item.'
• Document output schemas for all tools. E.g., search_by_name returns [{file_path: string, size: int, modified_date: ISO8601, is_directory: bool}, ...].
• Implement confirmation pattern for delete_item and write_file: add a 'confirm' parameter (default false) or return a confirmation_token requiring a second call with confirm=true.
• Add error handling: return structured errors with actionable guidance. E.g., 'Path not found: /nonexistent. Check the path with list_directory() first.' instead of generic 500 errors.
