Scored across 10 tools
Every tool has a clearly distinct purpose with no ambiguity. Each targets a specific S3 operation like copying, deleting, downloading, uploading, listing, or retrieving objects/buckets. The descriptions clearly differentiate between similar tools like delete_object vs delete_objects or get_object vs head_object.
All tools follow a consistent verb_noun naming pattern throughout (e.g., copy_object, delete_object, list_buckets). The naming is uniform with snake_case used consistently across all 10 tools, making them predictable and easy to understand.
With 10 tools, this server is well-scoped for S3 operations. Each tool earns its place by covering essential CRUD and management functions for S3 objects and buckets, from basic operations like put/get to advanced features like multi-object deletion and metadata retrieval.
The tool surface provides complete coverage for S3 object and bucket management. It includes all core CRUD operations (create/put, read/get/head/list, update via copy/replace, delete), plus specialized functions like multi-object deletion, file upload/download, and bucket listing, with no obvious gaps for the domain.
