Does the description clearly state what the tool does and how it differs from similar tools?
Description explicitly states 'Get metadata for a specific Drive file by ID' with a specific verb and resource, and lists the returned fields (name, type, size, etc.). This clearly distinguishes it from sibling tools like drive_create_file, drive_get_content, drive_list_files, and drive_search.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
