Built-in design generation now runs as an agentic MCP tool-loop (reusing the agent-rs BuiltInProvider), gated behind OPENPENCIL_DESIGN_AGENT_LOOP / the Settings experimental toggle; the orchestrator stays the default. - design-agent system prompt + in-process design toolset (parity-locked with the MCP surface) + flag-gated Intent::Design routing - spawn_agents execution as sequential sub-loops + live creation-mode badges (per-agent glow + 'N/M designing...' header) - new MCP tools: get_guidelines, ToolSearch, get_screenshot, get_editor_state, export_nodes, spawn_agents; style-guide local audit - #27 AI panel restyle: rounded tool cards + green check-rings, gray user bubbles, model-pill bottom toolbar, header, empty-state pills, the PARALLEL AGENTS (agent_team_size) 1x-6x chip dropdown - multi-chat tabs: ChatSessions model (Deref-to-active) + tab row UI (switch / close / + / Cmd+T) with each run bound to its tab Large checkpoint commit spanning the working tree (Rust shell crates).

# pen-react
|
|
|
|
React UI SDK for OpenPencil -- provider, hooks, panels, toolbar, and property editor components.
|
|
|
|
## Structure
|
|
|
|
### Core
|
|
|
|
- `src/context.ts` — `DesignEngineContext`: React context holding the `DesignEngine` instance
|
|
- `src/provider.tsx` — `DesignProvider`: provides engine to React tree. Supports uncontrolled mode (`initialDocument`) and controlled mode (`document` + `onDocumentChange`) with echo-loop prevention
|
|
|
|
### Hooks (`src/hooks/`)
|
|
|
|
- `use-design-engine.ts` — `useDesignEngine()`: gets engine from context, throws if outside provider
|
|
- `use-document.ts` — `useDocument()`: returns current `PenDocument`, re-renders on mutation
|
|
- `use-selection.ts` — `useSelection()`: returns `string[]` of selected node IDs
|
|
- `use-viewport.ts` — `useViewport()`: returns `ViewportState` (zoom, panX, panY)
|
|
- `use-active-tool.ts` — `useActiveTool()`: returns current `ToolType`
|
|
- `use-history.ts` — `useHistory()`: returns `{ canUndo, canRedo }`
|
|
- `use-active-node.ts` — `useActiveNode()`: returns the single active `PenNode` or null
|
|
- `use-active-page.ts` — `useActivePage()`: returns active page ID
|
|
- `use-hover.ts` — `useHover()`: returns hovered node ID
|
|
- `use-variables.ts` — `useVariables()`: returns document variables map
|
|
|
|
### Utilities (`src/utils/`)
|
|
|
|
- `use-engine-subscribe.ts` — `useEngineSubscribe(engine, event, getSnapshot)`: generic hook using `useSyncExternalStore` to subscribe to engine events with stable snapshot refs
|
|
|
|
### Stores (`src/stores/`)
|
|
|
|
- `ui-store.ts` — `useUIStore` (Zustand): pure UI state -- panel visibility, layer drag state, collapsed nodes. NOT engine state
|
|
|
|
### Components (`src/components/`)
|
|
|
|
- `design-canvas.tsx` — `DesignCanvas`: canvas element with CanvasKit rendering via `attachCanvas` + `attachInteraction` from pen-engine browser adapter
|
|
- `core-toolbar.tsx` — `CoreToolbar`: main tool selection bar
|
|
- `tool-button.tsx` — `ToolButton`: individual tool button with active state
|
|
- `shape-tool-dropdown.tsx` — `ShapeToolDropdown`: dropdown for shape tools (rectangle, ellipse, line, polygon)
|
|
- `layer-panel.tsx` — `LayerPanel`: document tree panel with drag-and-drop reordering
|
|
- `layer-item.tsx` — `LayerItem`: individual layer row with visibility/lock toggles
|
|
- `layer-context-menu.tsx` — `LayerContextMenu`: right-click context menu for layers
|
|
- `property-panel.tsx` — `PropertyPanel`: right-side property inspector (delegates to section components)
|
|
- `color-picker.tsx` — `ColorPicker`: color input with hex/opacity, gradient support
|
|
- `number-input.tsx` — `NumberInput`: numeric input with drag-to-adjust
|
|
- `section-header.tsx` — `SectionHeader`: collapsible section header
|
|
- `font-picker.tsx` — `FontPicker`: font family selector with search
|
|
- `variable-picker.tsx` — `VariablePicker`: design variable selector
|
|
- `icon-picker-dialog.tsx` — `IconPickerDialog`: icon search and selection
|
|
- `boolean-toolbar.tsx` — `BooleanToolbar`: union/subtract/intersect boolean operations
|
|
- `page-tabs.tsx` — `PageTabs`: multi-page tab bar
|
|
- `status-bar.tsx` — `StatusBar`: bottom status bar (zoom, selection info)
|
|
|
|
### Property sections (`src/components/sections/`)
|
