Tools are mostly distinct: get_user_info and add_activities are clear, while get_activities, get_summary, and get_timesheet overlap in domain but differ in output (list vs. summary vs. detailed timesheet). Descriptions effectively clarify these boundaries, so confusion is minimal.

All tool names follow a consistent verb_noun pattern in snake_case (e.g., get_activities, add_activities, get_timesheet). The verbs are limited to 'get' and 'add', which is intuitive for read/write operations, and there are no mixed conventions.

With 5 tools, the server is well-scoped for a time-tracking domain. Each tool covers a core need (user info, activities, summary, timesheet, adding activities) without superfluous or redundant endpoints.

The server provides good read coverage (user info, activities, summary, timesheet) and the ability to add activities, but lacks update and delete operations for activities. This is a notable gap for full lifecycle management, as users cannot correct or remove erroneous entries.
