Filesystem server has 10 tools with basic registration but significant quality gaps. Tool names follow verb_noun convention (read_file, write_file, delete_file) which is good. However, source code inspection reveals incomplete schemas and descriptions. Most tool registration files are not shown in detail, making full assessment difficult. Based on visible patterns: descriptions appear present but likely generic; parameter schemas not visible in provided code; no evidence of error handling guidance or output schema documentation. The server handles high-risk operations (delete_file, delete_directory, move_path) without visible confirmation patterns or detailed error recovery guidance.

• Provide complete input schemas for all tools with explicit parameter types (string, number, boolean, enum), descriptions (50-100 chars each), and constraints (min/max, regex patterns, allowed values). Use Zod schemas as shown in tool.ts but ensure they are visible in registration files.
• Add confirmation_request pattern to delete_file and delete_directory: require a 'confirm' boolean parameter or implement a two-step dry-run → execute flow to prevent accidental data loss.
• Document output schemas for all tools. E.g., list_files should return {files: [{name: string, path: string, size: number, type: 'file'|'directory', modified: string}], total: number}. Include pagination (limit, offset, next_cursor) for list_files.
• Implement error recovery guidance: when a file is not found, return 'File not found at /path/to/file. Check the path and try again.' When a write fails due to permissions, return 'Permission denied. Ensure the directory is writable and you have access.'
• Add parameter descriptions to all tools. E.g., read_file should document: 'path (string, required): Absolute or relative file path to read. Must be within FS_BASE_DIRECTORY if configured.' Include examples of valid paths in descriptions, not as sample values.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
