Build interactive AI chat widgets with buttons, forms, and bidirectional actions. Use when creating agentic UIs with clickable widgets, entity tagging (@mentions), composer tools, or server-handled widget actions. Covers full widget lifecycle. NOT when building simple text-only chat without interactive elements.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Building Chat Widgets
Create interactive widgets for AI chat with actions and entity tagging.
## Quick Start
```typescript
const chatkit = useChatKit({
api: { url: API_URL, domainKey: DOMAIN_KEY },
widgets: {
onAction: async (action, widgetItem) => {
if (action.type === "view_details") {
navigate(`/details/${action.payload.id}`);
}
},
},
});
```

## Action Handler Types
| Handler | Defined In | Processed By | Use Case |
|---------|------------|--------------|----------|
| `"client"` | Widget template | Frontend `onAction` | Navigation, local state |
| `"server"` | Widget template | Backend `action()` | Data mutation, widget replacement |
---
## Widget Lifecycle
```
1. Agent tool generates widget → yield WidgetItem
2. Widget renders in chat with action buttons
3. User clicks action → action dispatched
4. Handler processes action:
- client: onAction callback in frontend
- server: action() method in ChatKitServer
5. Optional: Widget replaced with updated state
```
---
## Core Patterns
### 1. Widget Templates
Define reusable widget layouts with dynamic data:
```json
{
"type": "ListView",
"children": [
{

How to install
mdr add mjunaidca/mjs-agent-skills/building-chat-widgets@sha256:c2663a7713f5a6b9The line at the top of this page pins the label git:20251222.3cc0c3c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
