Each tool targets a distinct campus resource or local action: refresh_source handles cache population, get_* tools read specific cached domains, and set_* tools change local state. The only potential overlap is refresh_source versus get_* refresh behavior, but the descriptions make the cache-refresh/read split clear.

All tools use snake_case and are mostly verb_noun, such as refresh_source, get_notice, and set_task_status. The lone exception is academic_summary, a noun phrase, but it remains readable and does not undermine the overall pattern.

16 tools is slightly above the typical 3-15 sweet spot, but the broad campus aggregation purpose justifies coverage across notices, grades, courses, tasks, schedule, setup, and local state. No tool appears redundant.

The surface covers the major lifecycle needs: source refresh, notice search/read/attachment extraction, grades/GPA, exams, courses/resources, tasks, schedule, service links, profile, capabilities, and setup. Minor gaps like no explicit get_profile or cache-clear exist but are workable.
