TDQS

A3.9/5.0

Scored across 40 tools

Disambiguation4/5

Most tools target distinct resource+action pairs, and descriptions clarify cases like small inline object I/O versus presigned URL transfers. There is some conceptual overlap between native b2_* and S3-compatible s3_* surfaces, especially around listing buckets, multipart uploads, and abandoned-upload analysis, but the tools remain mostly distinguishable.

Naming Consistency4/5

Tool names use consistent snake_case with clear b2_* and s3_* prefixes, and most follow a predictable verb_noun pattern. Minor deviations such as b2_unfinished_uploads and b2_reserve_trial_create_account prevent a perfect score.

Tool Count2/5

With 40 tools, the set is well above the typical 3-15 range and crosses the rubric's 25+ heavy threshold. The broad Backblaze B2 domain justifies many operations, but the combined native and S3-compatible surfaces make the count feel excessive.

Completeness4/5

Coverage is strong across buckets, objects, multipart uploads, keys, retention, legal holds, notifications, and usage analytics. Some lifecycle gaps remain, such as group creation/deletion and native hide/update-key operations, though several object gaps are covered through the S3-compatible tools.
