The four capture tools target distinct scopes (monitor, active window, matched window, arbitrary region), and the list tools cover distinct resources (windows, monitors, captures). capture_active_window vs capture_window could be briefly confused since both capture a window, but descriptions clarify the difference (focused vs class/title match).

All names follow a clean verb_noun snake_case pattern: capture_* for screenshots, list_* for enumeration, cleanup_* for deletion. The convention is applied uniformly with no deviations.

Eight tools is well-scoped for a screen-capture utility, with each tool earning its place across capture targets, discovery, and session cleanup. No redundant or filler tools.

The surface covers capture across monitor/window/region plus discovery (list_windows, list_monitors) and lifecycle management (list_captures, cleanup_captures), which is strong. Minor gaps like delayed/timed capture or annotation are absent but not essential to the core workflow.
