Scored across 9 tools
Most tools target clearly distinct resources and actions, with strong separation between course listing, file listing, downloading, assignment listing/details, and submission. Minor potential confusion exists between bb_list_course_files and bb_download_courseware, and between bb_assignment_details with download=true and bb_download_courseware, but the descriptions mostly resolve the boundaries.
All tools use a consistent bb_ prefix and snake_case, making names predictable. However, the set mixes verb_noun patterns (bb_list_courses, bb_submit_assignment) with noun-first names (bb_status, bb_announcements, bb_assignment_details), which is a minor but noticeable deviation from a uniform convention.
Nine tools is well-scoped for an LMS client covering authentication/session, courses, files, assignments, announcements, and submission. Each tool appears to earn its place without obvious redundancy or missing basic operations.
The surface covers the core BB workflow: login/session, course discovery, file listing/download, assignment listing/details/submission, and announcements. Minor gaps remain for common LMS needs such as a grades overview, discussion/forum access, or richer course metadata, and submission explicitly excludes tests and group assignments.
