Server has 19 tools with basic schemas and descriptions, but significant quality gaps. All tools have descriptions (positive), but most are under 100 chars and lack actionable context. Input schemas are present but minimal, most parameters lack type constraints, enums, or validation guidance. No output schemas documented. Error handling is absent; tools like ps_execute_command (IRREVERSIBLE) lack confirmation patterns or recovery guidance. Naming is verb-noun compliant but generic (e.g., 'get_system_status' vs 'describe_cpu_memory_disk_usage'). No tool annotations (readOnlyHint, destructiveHint, idempotentHint). Composition is reasonable (file ops, download, system, PowerShell separated), but tools like file_edit_file and file_write_file could be unified. Parameter descriptions are minimal, e.g., 'file_path' lacks format/constraint guidance. No pagination support on list_directory. Security: file operations accept arbitrary paths (path traversal risk); PowerShell execution is unrestricted (IRREVERSIBLE operations without confirmation).

• Document output schemas for all tools. Example: system_get_system_status should return {cpu_percent: number, memory_percent: number, disk_percent: number, timestamp: string}. Use JSON Schema in tool definition.
• Add confirmation/dry-run pattern to destructive tools. For file_delete_directory and ps_execute_command, add a 'confirm' boolean parameter or require explicit confirmation via a separate confirm_operation tool before executing.
• Enhance parameter descriptions with constraints and examples. E.g., 'file_path (string, absolute path, no ../ traversal): /home/user/data.txt' and 'command (string, max 1000 chars, no rm -rf): powershell command to execute'.
• Implement error handling with recovery guidance. Return structured errors: {error_code: 'FILE_NOT_FOUND', message: 'File /path/to/file not found', suggestion: 'Try list_directory("/path/to") to see available files', retryable: false}.
• Add tool annotations to schema. Mark file_delete_directory with destructiveHint=true, file_read_file with readOnlyHint=true, ps_execute_command with destructiveHint=true and idempotentHint=false.
