Scored across 9 tools
Most tools have distinct purposes, but 'create_space' and 'create_workspace' could be confused as both create spaces, though the latter includes tabs. Descriptions clarify that 'create_workspace' is for setting up a focused context, which helps differentiate it.
All tools follow a consistent verb_noun naming pattern (e.g., add_tab, create_space, list_spaces). The naming is uniform and predictable, making it easy to understand each tool's function at a glance.
With 9 tools, the server is well-scoped for managing Arc browser spaces and tabs. Each tool serves a clear purpose, covering core operations like creation, deletion, listing, and navigation without being overwhelming.
The toolset provides good coverage for space and tab management, including CRUD operations for spaces and tabs, and navigation tools. A minor gap is the lack of update operations for spaces or tabs, but agents can work around this by deleting and recreating as needed.
