A3.9/5.0

Scored across 4 tools

Disambiguation4/5

Most tools are clearly distinct, but get_job and get_screenshot overlap slightly since get_job already mentions returning screenshots. get_screenshot clarifies it fetches a specific rendering by client, width, and environment, so the boundary is mostly clear.

Naming Consistency5/5

All tool names follow a consistent verb_noun snake_case pattern: get_job, get_screenshot, list_clients, submit_preview. The verbs are clear and aligned with each action.

Tool Count5/5

Four tools is well-scoped for an email preview service: submit a job, check its status, list available clients, and fetch specific screenshots. Each tool serves a distinct part of the workflow without bloat.

Completeness4/5

The core lifecycle is covered: submit preview, poll status, discover clients, and fetch screenshots. There is no cancel/delete operation or job history retrieval, but those feel optional for this domain rather than essential gaps.
