Most tools have distinct purposes, such as getBucket for listing files, putObject for uploading, and aiPicMatting for image matting. However, some overlap exists between imageSearchPic and imageSearchText, both involving image retrieval, which could cause minor confusion. Overall, the descriptions clarify boundaries well.

The naming is mixed with camelCase (e.g., aiPicMatting) and snake_case (e.g., get_object_url), lacking a uniform pattern. While verbs like 'create', 'describe', 'get', and 'put' are used consistently, the inconsistency in case styles reduces predictability. It remains readable but not fully standardized.

With 18 tools, the count is slightly high but reasonable for a cloud storage and processing server. It covers file operations, image processing, and media tasks without feeling overly bloated. The scope justifies most tools, though it borders on being heavy.

The server provides good coverage for COS operations, including CRUD-like actions (get, put) and advanced processing (image, media, document tasks). Minor gaps exist, such as no direct update or delete tools for objects, but agents can work around this using upload/overwrite or other methods. The surface is largely complete for the domain.
