Scored across 30 tools
Most tools target a clearly distinct operation: read_phone vs show_layout vs diff vs apply form a coherent draft lifecycle, and the sorting/moving tools are well differentiated by description. Minor overlap remains between read_phone and reset_draft (both discard edits, one re-reads the device) and between arrange/place_at/swap as different granularities of the same move action.
The set is overwhelmingly snake_case verb_noun or verb (move, swap, apply, create_folder, sort_by_color, list_backups). A handful of tools are noun-only or bare nouns (icon_colors, screen_time, page_op, app_store_categories, diff), which breaks the pattern slightly but stays readable and predictable.
At 30 tools this is well past the heavy threshold for a single domain, and several could be consolidated (three sort_* tools, place_at/swap/close_gaps, undo/redo/reset_draft). Individual tools are meaningful, but the surface is large enough that an agent must scan a lot to pick correctly.
Coverage is strong: read, inspect, diff, preview, apply with token gating, backup listing, restore, undo/redo, and full folder/page/item manipulation are all present. Gaps are minor — no tool to add/remove/edit widgets themselves, and no way to pick or prune a specific backup beyond restore and list_backups.
