| name | gpui |
| description | GPUI framework knowledge covering actions/keybindings, async/background tasks, context management (App/Window/Context<T>/AsyncApp), custom elements (low-level Element trait), entity state management, event system, focus handling, global state, layout/styling (flexbox/CSS-like), and testing. Use when working with any GPUI framework concept, building GPUI applications, or needing guidance on GPUI-specific APIs and patterns. |
