Scored across 4 tools
Each tool has a clearly distinct role: URL construction (get_rss_feed_url), postings retrieval (search_jobs), counting only (count_jobs), and filter discovery (list_filter_values). The descriptions explicitly cross-reference each other (e.g. 'use count_jobs when only the number is needed') eliminating overlap ambiguity.
All names follow a consistent snake_case verb_noun pattern: get_rss_feed_url, search_jobs, count_jobs, list_filter_values. Verbs are varied but semantically appropriate rather than inconsistent.
Four tools is lean but each has a defensible purpose for a job-postings API, and no tool is redundant. Slightly under the ideal range, though nothing feels missing that a paginated search doesn't already cover.
The surface covers search, count, filter discovery, and RSS feed generation, which handles most lifecycle needs. Minor gap: there is no direct fetch-by-posting-ID tool, though search results already include full posting fields.
