Each tool has a single clear responsibility: enumerate all controls, read one control, write one control, or check connection state. list_features and get_feature differ by scope (all vs one), so an agent should not misselect between them.

The feature tools follow a consistent verb_noun pattern: list_features, get_feature, set_feature. connection_status breaks that pattern by being noun-only instead of something like get_connection_status, but the overall naming is still predictable.

Four tools is well-scoped for a focused overlay-control server. Each tool covers a necessary operation without redundancy or bloat.

The set provides enumeration, single-value reads, writes, and connection status, which fully covers the menu-control domain. Since the controls are fixed features rather than user-created resources, create/delete operations are not required.
