B3.3/5.0

Scored across 3 tools

Disambiguation5/5

Each tool occupies a distinct phase of the workflow: coverage answers 'which hosts are supported', transfer performs the capture/delivery, and verify checks the resulting receipt. There is no realistic scenario where an agent would confuse these three operations.

Naming Consistency4/5

All tools share a consistent 'downloadbridge_' prefix with a single-word suffix, which makes the family easy to scan. The only minor deviation is mixing a noun ('coverage') with verbs ('transfer', 'verify'), but readability is not harmed.

Tool Count5/5

Three tools is well-matched to a narrow, transactional service: check coverage, execute a transfer, verify a receipt. Nothing feels padded or missing at the surface level.

Completeness4/5

The core lifecycle (coverage → transfer → verify) is fully covered, which is strong for a focused service. However, there is no tool for checking transfer status/history, listing past transfers, or retrieving an api_token (registration is described as an external POST /register endpoint), leaving a few workaround-required gaps.
