Create a free sandbox object storage bucket; upload, download, list, inspect, and delete objects.
Scored across 8 tools
Every tool targets a distinct resource-action pair (bucket vs object vs permissions), and even similar operations like upload/download return clearly different URL types. No two tools overlap in a way that would cause an agent to misselect.
All tool names follow a consistent snake_case verb_noun pattern (create_bucket, delete_object, get_bucket_permissions, list_objects). Verb choices are descriptive and consistent across the set.
Eight tools is well-scoped for an object storage sandbox: bucket management, object lifecycle, metadata, and access checks are each represented. No redundant tools inflate the surface.
Core workflows—create bucket, upload, download, delete, list, and metadata—are covered, but bucket deletion is not exposed and explicit bucket listing is only indirectly available through permissions. This is a minor lifecycle gap rather than a blocking dead end.
