Arcangel Trademark Search

Each tool has a clearly distinct role: check_trademark initiates a search, get_trademark_check polls an in-flight search by search_id, and suggest_nice_classes handles classification. The async start/poll pair is explicitly explained in the descriptions, so an agent cannot reasonably confuse them with a single-shot lookup.

All tools are snake_case with a leading verb (check_, get_, suggest_), giving a predictable verb_noun pattern. The only minor deviation is suggest_nice_classes, which is verb_noun_noun and less symmetrical than the trademark-centric naming of the other two.

Three tools is lean but fits a narrowly scoped trademark-search service, and each tool corresponds to a real step in the workflow (search, retrieve, classify). It sits at the low end of the ideal range, so a small amount of additional surface would not hurt.

The core lifecycle is covered: initiate a search, poll the async result, and get Nice class suggestions, with the full clearance report gated behind a flag. Minor gaps exist, such as no way to list or re-fetch a previously completed search without its search_id and no direct mark-detail lookup.
