Each tool has a clearly distinct purpose with no ambiguity: toggl_current and toggl_stop handle the active timer, toggl_start initiates tracking, toggl_delete removes entries, and the summary tools (toggl_today, toggl_last_week, toggl_weekly) provide different timeframes. The tools toggl_projects stands alone for workspace management. There is no overlap in functionality that would cause misselection.

All tools follow a consistent 'toggl_verb' or 'toggl_noun' pattern with clear, descriptive names. The naming is uniform across all eight tools, using lowercase with underscores, making it predictable and easy to understand. There are no deviations in style or convention.

With 8 tools, the server is well-scoped for time tracking and project management. Each tool earns its place by covering essential operations like starting/stopping timers, viewing summaries, managing entries, and listing projects. This count is neither too sparse nor overwhelming for the domain.

The tool set provides strong coverage for core time tracking workflows, including CRUD operations (create via toggl_start, read via summary tools, delete via toggl_delete) and project listing. A minor gap exists in updating time entries (e.g., modifying descriptions or projects), but agents can work around this by deleting and recreating entries. Overall, it supports most common user actions without dead ends.
