# egui_inspection Wire protocol and `egui::Plugin` for live inspection of running egui apps and kittest harnesses. Two layers: - **`protocol`** (default feature): length-prefixed MessagePack messages used by `egui_kittest`'s inspector, the external `kittest_inspector` UI, and the `egui_kittest_mcp` server. - **`plugin`** (opt-in): an `egui::Plugin` implementation that streams frames + AccessKit tree updates to an inspector over a unix domain socket and applies received `InspectorCommand`s back into the running app. Auto-attaches when `EGUI_INSPECTION_SOCKET` is set.
