+# Changesets
+
+Hello and welcome! This folder has been automatically generated by `@changesets/cli`, a build tool that works
+with multi-package repos, or single-package repos to help you version and publish your code. You can
+find the full documentation for it [in the repository](https://github.com/changesets/changesets).
+
+## Adding a changeset
+
+To add a changeset, run `pnpm changeset` in the root of the repository. This will prompt you to select
+which packages have changed and what type of version bump (major, minor, or patch) should be applied.
+
+All `@json-render/*` packages are versioned together -- a changeset for any one of them will bump all
+packages to the same version.

 Instructions for AI coding agents working with this codebase.
 
+## Package Management
+
+**Always check the latest version before installing a package.**
+
+Before adding or updating any dependency, verify the current latest version on npm:
+
+```bash
+npm view <package-name> version
+```
+
+Or check multiple packages at once:
+
+```bash
+npm view ai version
+npm view @ai-sdk/provider-utils version
+npm view zod version
+```
+
+This ensures we don't install outdated versions that may have incompatible types or missing features.
+
 ## Code Style
 
 - Do not use emojis in code or UI
+- Do not use barrel files (index.ts that re-exports from other files)
+- Use shadcn CLI to add shadcn/ui components: `pnpm dlx shadcn@latest add <component>`

+setSpec(result); // Update UI with partial result
+
+// Get final result
+const finalSpec = compiler.getResult();
+```
+
+### AI Prompt Generation
+
+Generate system prompts from your catalog:

-### Built-in Validation
+Two expression forms:
+
+- **`{ "$path": "/state/key" }`** -- reads a value from the data model
+- **`{ "$cond": <condition>, "$then": <value>, "$else": <value> }`** -- evaluates a condition (same syntax as visibility conditions) and picks a branch
+
+### Actions
+
+Components can trigger actions, including the built-in `setState` action:
 
 ```json
 {
-  "type": "TextField",
+  "type": "Pressable",
-  "props": {
+  "props": { "action": "setState", "actionParams": { "path": "/activeTab", "value": "home" } },
-    "label": "Email",
+  "children": ["home-icon"]
-    "valuePath": "/form/email",
-    "checks": [
-      { "fn": "required", "message": "Email is required" },
-      { "fn": "email", "message": "Invalid email" }
-    ],
-    "validateOn": "blur"
-  }
 }
 ```
 
+The `setState` action updates the data model directly, which re-evaluates visibility conditions and dynamic prop expressions.

+    <strong>Concept:</strong> This page demonstrates how json-render can support A2UI. The examples are illustrative and may require adaptation for production use.
+  </p>
+</div>
+
+## Native A2UI Support
+
+`@json-render/core` is schema-agnostic. Define a catalog that matches A2UI's format and build a renderer that understands it - no conversion layer needed.
+
+## Example A2UI Message
+
+A2UI uses an adjacency list model - a flat list of components with ID references. This makes it easy to patch individual components:
+
+```json
+{
+  "surfaceUpdate": {
+    "surfaceId": "main",
+    "components": [
+      {
+        "id": "header",
+        "component": {
+          "Text": {
+            "text": {"literalString": "Book Your Table"},
+            "usageHint": "h1"
+          }
+        }
+      },
+      {
+        "id": "date-picker",
+        "component": {
+          "DateTimeInput": {
+            "label": {"literalString": "Select Date"},
+            "value": {"path": "/reservation/date"},
+            "enableDate": true
+          }
+        }
+      },
+      {
+        "id": "submit-btn",
+        "component": {
+          "Button": {
+            "child": "submit-text",
+            "action": {"name": "confirm_booking"}
+          }

+      }),
+    },
+    Button: {

+  root: z.string(),
+  catalogId: z.string().optional(),
+});
+
+// Complete A2UI message schema
+export const A2UIMessage = z.object({
+  surfaceUpdate: SurfaceUpdate.optional(),
+  dataModelUpdate: StateModelUpdate.optional(),
+  beginRendering: BeginRendering.optional(),
+  deleteSurface: z.object({ surfaceId: z.string() }).optional(),
+});
+```
+
+## Build an A2UI Renderer
+
+Create a renderer that processes the A2UI adjacency list format:
+
+```tsx
+import { a2uiCatalog } from './catalog';
+
+// Component registry
+const components = {
+  Text: ({ text, usageHint }) => {
+    const Tag = usageHint?.startsWith('h') ? usageHint : 'p';
+    return <Tag>{text}</Tag>;
+  },
+  Button: ({ children, action, onAction }) => (
+    <button onClick={() => onAction?.(action)}>{children}</button>
+  ),
+  DateTimeInput: ({ label, value, onChange }) => (
+    <label>
+      {label}
+      <input type="date" value={value} onChange={e => onChange?.(e.target.value)} />
+    </label>
+  ),
+  Column: ({ children }) => <div className="flex flex-col gap-2">{children}</div>,
+  Row: ({ children }) => <div className="flex gap-2">{children}</div>,
+};
+
+// Render A2UI surface
+export function renderA2UI(
+  componentMap: Map<string, any>,
+  dataModel: Record<string, any>,
+  rootId: string,
+  onAction?: (action: any) => void
+) {
+  function resolveBoundValue(bound: any) {
+    if (!bound) return undefined;
+    if (bound.literalString) return bound.literalString;
+    if (bound.path) {
+      const parts = bound.path.replace(/^\//, '').split('/');
+      let value = dataModel;
+      for (const p of parts) value = value?.[p];
+      return value;
+    }
+  }
+
+  function render(id: string): React.ReactNode {
+    const comp = componentMap.get(id);
+    if (!comp) return null;
+
+    const [type, props] = Object.entries(comp.component)[0];
+    const Component = components[type];
+    if (!Component) return null;
+
+    // Resolve props
+    const resolved: any = {};
+    for (const [key, val] of Object.entries(props as any)) {
+      if (key === 'child') {
+        resolved.children = render(val as string);
+      } else if (key === 'children' && val?.explicitList) {
+        resolved.children = val.explicitList.map(render);
+      } else if (val && typeof val === 'object' && ('literalString' in val || 'path' in val)) {
+        resolved[key] = resolveBoundValue(val);
+      } else {
+        resolved[key] = val;
+      }
+    }
+
+    return <Component key={id} {...resolved} onAction={onAction} />;
+  }
+
+  return render(rootId);
+}
+```
+
+## Usage
+
+```tsx
+const [components] = useState(() => new Map());
+const [dataModel, setDataModel] = useState({});
+const [rootId, setRootId] = useState<string | null>(null);
+
+// Process A2UI messages
+function handleMessage(msg: any) {
+  if (msg.surfaceUpdate) {
+    for (const comp of msg.surfaceUpdate.components) {
+      components.set(comp.id, comp);
+    }
+  }
+  if (msg.dataModelUpdate) {
+    setDataModel(prev => ({ ...prev, ...msg.dataModelUpdate.contents }));
+  }
+  if (msg.beginRendering) {
+    setRootId(msg.beginRendering.root);
+  }
+}
+
+// Render
+{rootId && renderA2UI(components, dataModel, rootId, handleAction)}
+```

+## Adaptive Cards Overview
+
+Adaptive Cards is a JSON-based format for platform-agnostic UI snippets. Cards have a `body` array of elements and an optional `actions` array for interactive buttons.
+
+### Example Adaptive Card
+
+```json
+{
+  "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
+  "type": "AdaptiveCard",
+  "version": "1.5",
+  "body": [
+    {
+      "type": "TextBlock",
+      "text": "Hello, Adaptive Cards!",
+      "size": "large",
+      "weight": "bolder"
+    },
+    {
+      "type": "Image",
+      "url": "https://example.com/image.png",
+      "altText": "Example image"
+    },
+    {
+      "type": "Container",
+      "items": [
+        {
+          "type": "TextBlock",
+          "text": "This is inside a container",

+        }
+      ]
+    },
+    {
+      "type": "ColumnSet",
+      "columns": [
+        {
+          "type": "Column",
+          "width": "auto",
+          "items": [
+            { "type": "TextBlock", "text": "Column 1" }
+          ]
+        },
+        {
+          "type": "Column",
+          "width": "stretch",
+          "items": [
+            { "type": "TextBlock", "text": "Column 2" }
+          ]
+        }
+      ]
+    },
+    {
+      "type": "Input.Text",
+      "id": "userInput",
+      "placeholder": "Enter your name",
+      "label": "Name"
+    }
+  ],
+  "actions": [
+    {
+      "type": "Action.Submit",
+      "title": "Submit"
+    },
+    {
+      "type": "Action.OpenUrl",
+      "title": "Learn More",
+      "url": "https://adaptivecards.io"
+    }
+  ]
+}
+```

+```
+
+## Building an Adaptive Cards Renderer
+
+Create a renderer that processes Adaptive Cards JSON. See the [A2UI integration](/docs/a2ui) page for a similar pattern. The key is mapping each Adaptive Card element type to a React component, resolving nested `items` and `columns` arrays recursively.
+
+## Usage Example
+
+Render an Adaptive Card and handle actions:
+
+```tsx
+'use client';
+
+import { AdaptiveCardRenderer } from './adaptive-card-renderer';
+
+const card = {
+  type: 'AdaptiveCard' as const,
+  version: '1.5',
+  body: [
+    {
+      type: 'TextBlock',
+      text: 'Contact Form',
+      size: 'large',
+      weight: 'bolder',
+    },
+    {
+      type: 'Input.Text',
+      id: 'name',
+      label: 'Your Name',
+      placeholder: 'Enter your name',
+    },
+    {
+      type: 'Input.Text',
+      id: 'message',
+      label: 'Message',
+      placeholder: 'Enter your message',
+      isMultiline: true,
+    },
+  ],
+  actions: [
+    {
+      type: 'Action.Submit',
+      title: 'Send',
+      data: { action: 'submitForm' },
+    },
+  ],
+};
+
+export function ContactCard() {
+  const handleAction = (action: any, inputData: Record<string, unknown>) => {
+    console.log('Action:', action);
+    console.log('Input data:', inputData);
+    
+    // Send to your backend
+    fetch('/api/submit', {
+      method: 'POST',
+      headers: { 'Content-Type': 'application/json' },
+      body: JSON.stringify({ action, data: inputData }),
+    });
+  };
+
+  return <AdaptiveCardRenderer card={card} onAction={handleAction} />;
+}
+```
+
+## Handling Action.Execute for Bots
+
+For bot scenarios, handle `Action.Execute` with the verb and data:
+
+```typescript
+interface ActionExecutePayload {
+  action: {
+    type: 'Action.Execute';
+    verb: string;
+    data?: unknown;
+  };
+  inputs: Record<string, unknown>;
+}
+
+async function handleBotAction(payload: ActionExecutePayload) {
+  const response = await fetch('/api/bot/action', {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify({
+      verb: payload.action.verb,
+      data: payload.action.data,
+      inputs: payload.inputs,
+    }),
+  });
+  
+  // Bot may return a new card to render
+  const result = await response.json();
+  if (result.card) {
+    return result.card; // New AdaptiveCard to render
+  }
+}
+```

+
+## What is AG-UI?
+
+AG-UI is an open protocol for connecting AI agents to user interfaces. It provides a standardized way for agents to render UI components, handle user input, and manage state. The protocol uses events streamed over HTTP to update the UI in real-time.
+
+## AG-UI Event Types
+
+AG-UI defines several event types for agent-UI communication:
+
+- `TEXT_MESSAGE_START` / `TEXT_MESSAGE_CONTENT` / `TEXT_MESSAGE_END` — Streaming text messages
+- `TOOL_CALL_START` / `TOOL_CALL_ARGS` / `TOOL_CALL_END` — Tool/function calls
+- `STATE_SNAPSHOT` / `STATE_DELTA` — State updates
+- `CUSTOM` — Custom events for UI rendering
+
+### Example AG-UI Event Stream
+
+```json
+{"type": "RUN_STARTED", "threadId": "thread-123", "runId": "run-456"}
+{"type": "TEXT_MESSAGE_START", "messageId": "msg-1", "role": "assistant"}
+{"type": "TEXT_MESSAGE_CONTENT", "messageId": "msg-1", "delta": "Here's a dashboard for you:"}
+{"type": "TEXT_MESSAGE_END", "messageId": "msg-1"}
+{"type": "TOOL_CALL_START", "toolCallId": "tc-1", "toolCallName": "render_ui"}
+{"type": "TOOL_CALL_ARGS", "toolCallId": "tc-1", "delta": "{\"component\": \"Dashboard\", \"props\": {\"title\": \"Sales\"}}"}
+{"type": "TOOL_CALL_END", "toolCallId": "tc-1"}
+{"type": "RUN_FINISHED"}
+```
+
+## Define the AG-UI Schema
+
+Define schemas for AG-UI event types:
+
+```typescript
+import { z } from 'zod';
+
+// Base event schema
+const BaseEvent = z.object({
+  type: z.string(),
+  timestamp: z.number().optional(),

+
+// Text message events
+const TextMessageStart = BaseEvent.extend({
+  type: z.literal('TEXT_MESSAGE_START'),
+  messageId: z.string(),
+  role: z.enum(['user', 'assistant']),
+});
+
+const TextMessageContent = BaseEvent.extend({
+  type: z.literal('TEXT_MESSAGE_CONTENT'),
+  messageId: z.string(),
+  delta: z.string(),
+});
+
+const TextMessageEnd = BaseEvent.extend({
+  type: z.literal('TEXT_MESSAGE_END'),
+  messageId: z.string(),
+});
+
+// Tool call events
+const ToolCallStart = BaseEvent.extend({
+  type: z.literal('TOOL_CALL_START'),
+  toolCallId: z.string(),
+  toolCallName: z.string(),
+  parentMessageId: z.string().optional(),
+});
+
+const ToolCallArgs = BaseEvent.extend({

+  delta: z.string(),
+});
+
+const ToolCallEnd = BaseEvent.extend({
+  type: z.literal('TOOL_CALL_END'),
+  toolCallId: z.string(),
+});
+
+// State events
+const StateSnapshot = BaseEvent.extend({
+  type: z.literal('STATE_SNAPSHOT'),
+  snapshot: z.record(z.unknown()),
+});
+
+const StateDelta = BaseEvent.extend({
+  type: z.literal('STATE_DELTA'),
+  delta: z.array(z.object({
+    op: z.enum(['add', 'remove', 'replace']),
+    path: z.string(),
+    value: z.unknown().optional(),
+  })),
+});
+
+// Custom event for UI components
+const CustomEvent = BaseEvent.extend({
+  type: z.literal('CUSTOM'),
+  name: z.string(),
+  value: z.unknown(),
+});
+
+// Run lifecycle events
+const RunStarted = BaseEvent.extend({
+  type: z.literal('RUN_STARTED'),
+  threadId: z.string(),
+  runId: z.string(),
+});
+
+const RunFinished = BaseEvent.extend({
+  type: z.literal('RUN_FINISHED'),
+});
+
+const RunError = BaseEvent.extend({
+  type: z.literal('RUN_ERROR'),
+  message: z.string(),
+  code: z.string().optional(),
+});
+
+// Union of all events
+export const AGUIEvent = z.discriminatedUnion('type', [
+  TextMessageStart,
+  TextMessageContent,
+  TextMessageEnd,
+  ToolCallStart,
+  ToolCallArgs,
+  ToolCallEnd,
+  StateSnapshot,
+  StateDelta,
+  CustomEvent,
+  RunStarted,
+  RunFinished,
+  RunError,
+]);
+

+
+## Installation
+
+```bash
+npm install ai
+```
+
+## API Route Setup
+
+```typescript
+// app/api/generate/route.ts
+import { streamText } from 'ai';
+import { catalog } from '@/lib/catalog';
+
+export async function POST(req: Request) {
+  const { prompt, currentTree } = await req.json();
+  
+  // Generate system prompt from catalog
+  const systemPrompt = catalog.prompt();
+  
+  // Optionally include current UI state for context
+  const contextPrompt = currentTree 
+    ? `\n\nCurrent UI state:\n${JSON.stringify(currentTree, null, 2)}`
+    : '';
+
+  const result = streamText({

+    system: systemPrompt + contextPrompt,
+    prompt,
+  });
+
+  return result.toTextStreamResponse();
+}
+```
+
+## Client-Side Hook
+
+Use `useUIStream` on the client:
+
+```tsx
+'use client';
+
+import { useUIStream, Renderer } from '@json-render/react';
+
+function GenerativeUI() {
+  const { spec, isStreaming, error, send } = useUIStream({
+    api: '/api/generate',
+  });
+
+  return (
+    <div>
+      <button 
+        onClick={() => send('Create a dashboard with metrics')}
+        disabled={isStreaming}
+      >
+        {isStreaming ? 'Generating...' : 'Generate'}
+      </button>
+      
+      {error && <p className="text-red-500">{error.message}</p>}
+      
+      <Renderer spec={spec} registry={registry} loading={isStreaming} />
+    </div>
+  );
+}
+```
+
+## Prompt Engineering
+
+The `catalog.prompt()` method creates an optimized system prompt that:
+
+- Lists all available components and their props
+- Describes available actions
+- Specifies the expected JSON output format
+- Includes examples for better generation
+
+## Custom System Prompts
+
+Pass custom rules to tailor AI behavior:
+
+```typescript
+const systemPrompt = catalog.prompt({
+  customRules: [
+    'Always use Card components for grouping related content',
+    'Prefer horizontal layouts (Row) for metrics',
+    'Use consistent spacing with padding="md"',
+  ],
+});

+```
+
+### Catalog Methods
+
+```typescript
+// Generate AI system prompt
+const systemPrompt = catalog.prompt({
+  customRules: ["Always use Card as root element"],
+});
+
+// Validate a spec from AI
+const result = catalog.validate(aiOutput);
+if (result.success) {

+} else {
+  console.error(result.error);
+}
+
+// Get Zod schema for custom validation
+const schema = catalog.zodSchema();
+const parsed = schema.safeParse(aiOutput);
+
+// Export as JSON Schema (for structured outputs)
+const jsonSchema = catalog.jsonSchema();
+```
+
+## Schema System
+
+json-render uses a flexible schema system that defines both the AI output format (spec) and what catalogs must provide. Each renderer package provides its own schema (e.g., @json-render/react exports `schema`).
+
+### schema
+
+The schema for flat UI element trees. This is exported from @json-render/react.
+
+```typescript
+import { defineCatalog } from '@json-render/core';
+import { schema } from '@json-render/react';
+
+// schema defines:
+// - Spec shape: { root: string, elements: Record<string, UIElement> }
+// - Catalog shape: { components: {...}, actions: {...} }
+
+const catalog = defineCatalog(schema, {
+  components: {
+    Card: {
+      props: z.object({ title: z.string() }),
+      slots: ["default"],
+      description: "Container card",
+    },
+  },
+  actions: {
+    submit: {
+      params: z.object({ formId: z.string() }),
+      description: "Submit a form",
+    },
+  },
+});
+```
+
+### defineSchema
+
+Create custom schemas for different output formats (e.g., page-based, block-based).
+
+```typescript
+import { defineSchema } from '@json-render/core';
+
+const mySchema = defineSchema((s) => ({
+  // What the AI outputs (spec)
+  spec: s.object({
+    title: s.string(),
+    blocks: s.array(s.object({
+      type: s.ref("catalog.blocks"),
+      content: s.any(),
+    })),
+  }),
+
+  // What the catalog must provide
+  catalog: s.object({
+    blocks: s.map({
+      props: s.zod(),
+      description: s.string(),
+    }),
+  }),
+}));
+```
+
+### Schema Builder API
+
+The schema builder provides these methods:
+
+```typescript
+// Primitive types
+s.string()           // String value
+s.number()           // Number value
+s.boolean()          // Boolean value
+s.any()              // Any value
+
+// Compound types
+s.array(item)        // Array of items
+s.object({ ... })    // Object with shape
+s.record(value)      // Record/map with value type
+
+// Catalog references (for type safety)
+s.ref("catalog.components")      // Reference to catalog key (becomes enum)
+s.propsOf("catalog.components")  // Props schema from catalog entry
+
+// Catalog definitions
+s.map({ props: s.zod(), ... })   // Map of named entries with shared shape
+s.zod()                          // Placeholder for user-provided Zod schema
+
+// Modifiers
+s.optional()         // Mark field as optional
+```
+
+## Zod Schemas
+
+Pre-built Zod schemas for common json-render types:
+
+### Dynamic Value Schemas
+
+```typescript
+import {
+  DynamicValueSchema,    // string | number | boolean | null | { path: string }
+  DynamicStringSchema,   // string | { path: string }
+  DynamicNumberSchema,   // number | { path: string }
+  DynamicBooleanSchema,  // boolean | { path: string }
+} from '@json-render/core';
+
+// Dynamic values can be literals or data path references
+type DynamicValue<T> = T | { path: string };
+
+// Example: a prop that can be a literal or bound to data
+const schema = z.object({
+  label: DynamicStringSchema,  // "Hello" or { path: "/user/name" }
+});
+```
+
+### Visibility & Logic Schemas
+
+```typescript
+import {
+  VisibilityConditionSchema,  // Full visibility condition
+  LogicExpressionSchema,      // Logic operators (and, or, not, eq, gt, etc.)
+} from '@json-render/core';
+
+// Use in component props that need conditional rendering
+const schema = z.object({
+  visible: VisibilityConditionSchema.optional(),
+});
+```
+
+### Action Schemas
+
+```typescript
+import {
+  ActionSchema,           // Full action definition
+  ActionConfirmSchema,    // Confirmation dialog config
+  ActionOnSuccessSchema,  // Success handler config
+  ActionOnErrorSchema,    // Error handler config
+} from '@json-render/core';
+```
+
+### Validation Schemas
+
+```typescript
+import {
+  ValidationCheckSchema,   // Single validation check
+  ValidationConfigSchema,  // Full validation config with checks array
+} from '@json-render/core';
+```
+
+## SpecStream
+
+SpecStream is json-render's streaming format for progressively building specs from JSONL patches.
+
+### createSpecStreamCompiler
+
+Create a streaming compiler that incrementally builds a spec:
+
+```typescript
+import { createSpecStreamCompiler } from '@json-render/core';
+
+const compiler = createSpecStreamCompiler<MySpec>();
+
+// Process streaming chunks
+const { result, newPatches } = compiler.push(chunk);
+
+// Get final result
+const spec = compiler.getResult();
+
+// Reset for reuse
+compiler.reset();
+```
+
+### compileSpecStream
+
+Compile an entire SpecStream string at once:
+
+```typescript
+import { compileSpecStream } from '@json-render/core';
+
+const jsonl = `{"op":"add","path":"/root","value":{}}
+{"op":"add","path":"/root/type","value":"Card"}`;
+
+const spec = compileSpecStream<MySpec>(jsonl);
+```
+
+### Low-Level Utilities
+
+```typescript
+import {
+  parseSpecStreamLine,
+  applySpecStreamPatch,
+} from '@json-render/core';
+
+// Parse a single line
+const patch = parseSpecStreamLine('{"op":"add","path":"/root","value":{}}');
+
+// Apply patch to object (mutates in place)
+const obj = {};
+applySpecStreamPatch(obj, patch);
+```
+
+### SpecStream Types
+
+Fully compliant with [RFC 6902](https://datatracker.ietf.org/doc/html/rfc6902):
+
+```typescript
+interface SpecStreamLine {
+  op: 'add' | 'remove' | 'replace' | 'move' | 'copy' | 'test';
+  path: string;
+  value?: unknown;  // Required for add, replace, test
+  from?: string;    // Required for move, copy
+}
+
+interface SpecStreamCompiler<T> {
+  push(chunk: string): { result: T; newPatches: SpecStreamLine[] };
+  getResult(): T;
+  getPatches(): SpecStreamLine[];
+  reset(): void;
+}
+```

+import { getByPath, setByPath } from '@json-render/core';
+
+// Get value by JSON Pointer path
+const value = getByPath(data, '/user/name');  // "Alice"
+
+// Set value by path (mutates object)
+setByPath(data, '/user/email', 'alice@example.com');
+```
+
+### resolveDynamicValue
+
+```typescript
+import { resolveDynamicValue } from '@json-render/core';
+
+// Resolve a dynamic value against data
+const name = resolveDynamicValue("Hello", data);        // "Hello"
+const name2 = resolveDynamicValue({ path: "/user/name" }, data);  // "Alice"
+```
+
+### findFormValue
+
+```typescript
+import { findFormValue } from '@json-render/core';
+
+// Find form values regardless of path format
+// Checks: params.name, params["form.name"], data["form.name"], data.form.name
+const value = findFormValue("name", params, data);
+```
+
+## evaluateVisibility
+
+Evaluates a visibility condition against data and auth state.
+
+```typescript
+function evaluateVisibility(
+  condition: VisibilityCondition | undefined,
+  data: Record<string, unknown>,
+  auth?: AuthState
+): boolean
+
+type VisibilityCondition =
+  | { path: string }
+  | { auth: 'signedIn' | 'signedOut' | string }
+  | { and: VisibilityCondition[] }
+  | { or: VisibilityCondition[] }
+  | { not: VisibilityCondition }
+  | { eq: [DynamicValue, DynamicValue] }
+  | { gt: [DynamicValue, DynamicValue] }
+  | { gte: [DynamicValue, DynamicValue] }
+  | { lt: [DynamicValue, DynamicValue] }
+  | { lte: [DynamicValue, DynamicValue] };
+```
+
+## Types
+
+### UIElement
+
+```typescript
+interface UIElement {
+  key: string;
+  type: string;
+  props: Record<string, unknown>;
+  children?: string[];          // Keys of child elements
+  visible?: VisibilityCondition;
+  validation?: ValidationSchema;
+}
+```
+
+### Spec (Element Tree)
+
+```typescript
+interface Spec {
+  root: string | null;         // Key of root element
+  elements: Record<string, UIElement>;
+}
+```
+
+Elements are stored as a flat map with string keys. The tree structure is built by following the `children` arrays.
+
+### Action
+
+```typescript
+interface Action {
+  name: string;
+  params?: Record<string, unknown>;
+  confirm?: {
+    title: string;
+    message: string;
+    variant?: 'default' | 'danger';
+  };
+  onSuccess?: { set: Record<string, unknown> };
+  onError?: { set: Record<string, unknown> };
+}
+```
+
+### ValidationSchema
+
+```typescript
+interface ValidationSchema {
+  checks: ValidationCheck[];
+  validateOn?: 'change' | 'blur' | 'submit';
+}
+
+interface ValidationCheck {
+  fn: string;
+  args?: Record<string, unknown>;
+  message: string;
+}
+```

+# Catalog
+
+The catalog defines what AI can generate. It's your guardrail.
+
+## What is a Catalog?
+
+A catalog is a schema that defines:
+
+- **Components** — UI elements AI can create (with props and optional slots)
+- **Actions** — Operations AI can trigger
+- **Functions** — Custom validation or transformation functions
+
+## Creating a Catalog
+
+```typescript
+import { defineCatalog } from '@json-render/core';
+import { schema } from '@json-render/react';
+import { z } from 'zod';
+
+const catalog = defineCatalog(schema, {
+  components: {
+    // Define each component with its props schema
+    Card: {
+      props: z.object({
+        title: z.string(),
+        description: z.string().nullable(),
+        padding: z.enum(['sm', 'md', 'lg']).nullable(),
+      }),
+      slots: ["default"], // Can contain other components
+      description: "Container card for grouping content",
+    },
+    
+    Metric: {
+      props: z.object({
+        label: z.string(),
+        valuePath: z.string(), // JSON Pointer to data
+        format: z.enum(['currency', 'percent', 'number']),
+      }),
+      description: "Display a single metric value",
+    },
+  },
+  
+  actions: {
+    submit_form: {
+      params: z.object({
+        formId: z.string(),
+      }),
+      description: 'Submit a form',
+    },
+    
+    export_data: {
+      params: z.object({
+        format: z.enum(['csv', 'pdf', 'json']),
+      }),
+      description: 'Export data in various formats',
+    },
+  },
+});
+```
+
+## Component Definition
+
+Each component in the catalog has:
+
+```typescript
+{
+  props: z.object({...}),  // Zod schema for props (use .nullable() for optional)
+  slots?: string[],        // Named slots for children (e.g., ["default"])
+  description?: string,    // Help AI understand when to use it
+}
+```
+
+Use `slots: ["default"]` for components that can contain children. The slot name corresponds to where child elements are rendered.
+
+## Generating AI Prompts
+
+Use the `catalog.prompt()` method to generate a system prompt for AI:
+
+```typescript
+// Generate a system prompt from your catalog
+const systemPrompt = catalog.prompt();
+
+// Or with custom rules for the AI
+const customPrompt = catalog.prompt({
+  customRules: [
+    "Always use Card as the root element for forms",
+    "Group related inputs in a Stack with direction=vertical",
+  ],
+});
+
+// Pass this to your AI model as the system prompt
+```

+# Changelog
+
+Notable changes and updates to json-render.
+
+## v0.4.0
+
+February 2026
+
+### New: Custom Schema System
+
+Create custom output formats with `defineSchema`. Each renderer now defines its own schema, enabling completely different spec formats for different use cases.
+
+```typescript
+import { defineSchema } from "@json-render/core";
+
+const mySchema = defineSchema((s) => ({
+  spec: s.object({
+    pages: s.array(s.object({
+      title: s.string(),
+      blocks: s.array(s.ref("catalog.blocks")),
+    })),
+  }),
+  catalog: s.object({
+    blocks: s.map({ props: s.zod(), description: s.string() }),
+  }),
+}), {
+  promptTemplate: myPromptTemplate,
+});
+```
+
+### New: Component Slots
+
+Components can now define which slots they accept. Use `["default"]` for regular children, or named slots like `["header", "footer"]` for more complex layouts.
+
+```typescript
+const catalog = defineCatalog(schema, {
+  components: {
+    Card: {
+      props: z.object({ title: z.string() }),
+      slots: ["default"],  // accepts children
+      description: "A card container",
+    },
+    Layout: {
+      props: z.object({}),
+      slots: ["header", "content", "footer"],  // named slots
+      description: "Page layout with header, content, footer",
+    },
+  },
+});
+```
+
+### New: AI Prompt Generation
+
+Catalogs now generate AI system prompts automatically with `catalog.prompt()`. The prompt includes all component definitions, props schemas, and action descriptions - ensuring the AI only generates valid specs.
+
+```typescript
+import { defineCatalog } from "@json-render/core";
+import { schema } from "@json-render/react/schema";
+
+const catalog = defineCatalog(schema, {
+  components: { /* ... */ },
+  actions: { /* ... */ },
+});
+
+// Generate system prompt for AI
+const systemPrompt = catalog.prompt();
+
+// Use with any AI SDK
+const result = await streamText({
+  model: "claude-haiku-4.5",
+  system: systemPrompt,
+  prompt: userMessage,
+});
+```
+
+### New: @json-render/remotion
+
+Generate AI-powered videos with Remotion. Define video catalogs, stream timeline specs, and render with the Remotion Player.
+
+```tsx
+import { Player } from "@remotion/player";
+import { Renderer, schema, standardComponentDefinitions } from "@json-render/remotion";
+
+const catalog = defineCatalog(schema, {
+  components: standardComponentDefinitions,
+  transitions: standardTransitionDefinitions,
+});
+
+<Player
+  component={Renderer}
+  inputProps={{ spec }}
+  durationInFrames={spec.composition.durationInFrames}
+  fps={spec.composition.fps}
+  compositionWidth={spec.composition.width}
+  compositionHeight={spec.composition.height}
+/>
+```
+
+Includes 10 standard video components (TitleCard, TypingText, SplitScreen, etc.), 7 transition types, and the ClipWrapper utility for custom components.
+
+### New: SpecStream
+
+SpecStream is json-render's streaming format for progressively building specs from JSONL patches. The new compiler API makes it easy to process streaming AI responses.
+
+```typescript
+import { createSpecStreamCompiler } from "@json-render/core";
+
+const compiler = createSpecStreamCompiler<MySpec>();
+
+// Process streaming chunks
+const { result, newPatches } = compiler.push(chunk);
+setSpec(result); // Update UI with partial result
+```
+
+### Improved: Dashboard Example
+
+The dashboard example is now a full-featured accounting dashboard with:
+
+- Persistent SQLite database with Drizzle ORM
+- RESTful API for customers, invoices, expenses, accounts
+- Draggable widget reordering
+- AI-powered widget generation with streaming
+- Real data binding to database records
+
+### Improved: Documentation
+
+- Interactive playground for testing specs
+- New guides: Custom Schema, Streaming, Code Export
+- Full API reference for all packages
+- Integration guides: A2UI, AG-UI, Adaptive Cards, OpenAPI
+
+### Breaking Changes
+
+- `UITree` type renamed to `Spec`
+- Schema is now imported from renderer packages (`@json-render/react`) not core
+- `defineCatalog` now requires a schema as first argument
+
+---
+
+## v0.3.0
+
+January 2026
+
+Internal release with codegen foundations.
+
+- Added `@json-render/codegen` package (spec traversal and JSX serialization)
+- Configurable AI model via environment variables
+- Documentation improvements and bug fixes
+
+*Note: Only @json-render/core was published to npm for this release.*
+
+---
+
+## v0.2.0
+
+January 2026
+
+Initial public release.
+
+- Core catalog and spec types
+- React renderer with contexts for data, actions, visibility
+- AI prompt generation from catalogs
+- Basic streaming support
+- Dashboard example application

+
+# Code Export
+
+Export generated UI as standalone code for your framework.
+
+## Overview
+
+While json-render is designed for dynamic rendering, you can export generated UI as static code. The code generation is intentionally project-specific so you have full control over:
+
+- Component templates (standalone, no json-render dependencies)
+- Package.json and project structure
+- Framework-specific patterns (Next.js, Remix, etc.)
+- How data is passed to components
+
+## Architecture
+
+Code export is split into two parts:
+
+### 1. @json-render/codegen (utilities)
+
+Framework-agnostic utilities for building code generators:
+
+```typescript
+import {
+  traverseSpec,          // Walk the UI spec
+  collectUsedComponents, // Get all component types used
+  collectStatePaths,      // Get all data binding paths
+  collectActions,        // Get all action names
+  serializeProps,        // Convert props to JSX string
+} from '@json-render/codegen';
+```
+
+### 2. Your Project (generator)
+
+Custom code generator specific to your project and framework:
+
+```typescript
+// lib/codegen/generator.ts
+import { collectUsedComponents, serializeProps } from '@json-render/codegen';
+
+export function generateNextJSProject(spec: Spec): GeneratedFile[] {
+  const components = collectUsedComponents(spec);
+  
+  return [
+    { path: 'package.json', content: '...' },
+    { path: 'app/page.tsx', content: '...' },
+    // ... component files
+  ];
+}
+```
+
+## Example: Next.js Export
+
+See the dashboard example for a complete implementation that exports:
+
+- `package.json` - Dependencies and scripts
+- `tsconfig.json` - TypeScript config
+- `next.config.js` - Next.js config
+- `app/layout.tsx` - Root layout
+- `app/globals.css` - Global styles
+- `app/page.tsx` - Generated page with data
+- `components/ui/*.tsx` - Standalone components
+
+## Standalone Components
+
+The exported components are standalone with no json-render dependencies. They receive data as props instead of using hooks:
+
+```tsx
+// Generated component (standalone)
+interface MetricProps {
+  label: string;
+  valuePath: string;
+  data?: Record<string, unknown>;
+}
+
+export function Metric({ label, valuePath, data }: MetricProps) {
+  const value = data ? getByPath(data, valuePath) : undefined;
+  return (
+    <div>
+      <span>{label}</span>
+      <span>{formatValue(value)}</span>
+    </div>
+  );
+}
+```
+
+## Using the Utilities
+
+### traverseSpec
+
+```typescript
+import { traverseSpec } from '@json-render/codegen';
+
+traverseSpec(spec, (element, depth, parent) => {
+  console.log(' '.repeat(depth * 2) + element.type);
+});
+```
+
+### collectUsedComponents
+
+```typescript
+import { collectUsedComponents } from '@json-render/codegen';
+
+const components = collectUsedComponents(spec);

+
+# Custom Schema & Renderer
+
+Build your own schema and renderer with `@json-render/core`.
+
+## Overview
+
+`@json-render/core` is schema-agnostic. While `@json-render/react` provides a ready-to-use schema and renderer, you can create your own to match any JSON structure - whether it's a domain-specific format, an existing protocol, or something entirely custom.
+
+## 1. Define Your Schema
+
+Start by defining the JSON structure your system will use. Here's an example of a simple dashboard schema:
+
+```json
+{
+  "layout": "grid",
+  "columns": 2,
+  "widgets": [
+    {
+      "type": "metric",
+      "title": "Revenue",
+      "value": "$12,345",
+      "trend": "up"
+    },
+    {
+      "type": "chart",
+      "title": "Sales",
+      "chartType": "line",
+      "dataKey": "salesData"
+    },
+    {
+      "type": "table",
+      "title": "Recent Orders",
+      "columns": ["id", "customer", "amount"],
+      "dataKey": "orders"
+    }
+  ]
+}
+```
+
+## 2. Create the Catalog
+
+Define a catalog that describes your components and validates props:
+
+```typescript
+import { createCatalog } from '@json-render/core';
+import { z } from 'zod';
+
+export const dashboardCatalog = createCatalog({
+  components: {
+    metric: {
+      description: 'Displays a single metric value',
+      props: z.object({
+        title: z.string(),
+        value: z.string(),
+        trend: z.enum(['up', 'down', 'flat']).optional(),
+        change: z.string().optional(),
+      }),
+    },
+    chart: {
+      description: 'Renders a chart visualization',
+      props: z.object({
+        title: z.string(),
+        chartType: z.enum(['line', 'bar', 'pie', 'area']),
+        dataKey: z.string(),
+        height: z.number().optional(),
+      }),
+    },
+    table: {
+      description: 'Displays tabular data',
+      props: z.object({
+        title: z.string(),
+        columns: z.array(z.string()),
+        dataKey: z.string(),
+        pageSize: z.number().optional(),
+      }),
+    },
+    text: {
+      description: 'Displays text content',
+      props: z.object({
+        content: z.string(),
+        variant: z.enum(['heading', 'body', 'caption']).optional(),
+      }),
+    },
+  },
+});
+```
+
+## 3. Define the Root Schema
+
+Create a schema for the overall document structure:
+
+```typescript
+import { z } from 'zod';
+
+const WidgetSchema = z.object({
+  type: z.string(),
+  title: z.string().optional(),
+  // Additional props validated by catalog
+}).passthrough();
+
+export const DashboardSchema = z.object({
+  layout: z.enum(['grid', 'stack', 'tabs']),
+  columns: z.number().optional(),
+  widgets: z.array(WidgetSchema),
+});
+
+export type Dashboard = z.infer<typeof DashboardSchema>;
+export type Widget = z.infer<typeof WidgetSchema>;
+```
+
+## 4. Build the Renderer
+
+Create a renderer that maps your schema to React components:
+
+```tsx
+import React from 'react';
+import { dashboardCatalog } from './catalog';
+import type { Dashboard, Widget } from './schema';
+
+// Widget component registry
+const widgetComponents: Record<string, React.FC<any>> = {
+  metric: ({ title, value, trend, change }) => (
+    <div className="p-4 rounded-lg border">
+      <p className="text-sm text-muted-foreground">{title}</p>
+      <p className="text-2xl font-bold">{value}</p>
+      {trend && (
+        <p className={`text-sm ${trend === 'up' ? 'text-green-500' : 'text-red-500'}`}>
+          {trend === 'up' ? '+' : '-'}{change}
+        </p>
+      )}
+    </div>
+  ),
+
+  chart: ({ title, chartType, data }) => (
+    <div className="p-4 rounded-lg border">
+      <p className="font-medium mb-2">{title}</p>
+      <div className="h-48 bg-muted rounded flex items-center justify-center">
+        {/* Your chart library here */}
+        <span className="text-muted-foreground">{chartType} chart</span>
+      </div>
+    </div>
+  ),
+
+  table: ({ title, columns, data }) => (
+    <div className="p-4 rounded-lg border">
+      <p className="font-medium mb-2">{title}</p>
+      <table className="w-full text-sm">
+        <thead>
+          <tr>
+            {columns.map((col: string) => (
+              <th key={col} className="text-left p-2 border-b">{col}</th>
+            ))}
+          </tr>
+        </thead>
+        <tbody>
+          {data?.map((row: any, i: number) => (
+            <tr key={i}>
+              {columns.map((col: string) => (
+                <td key={col} className="p-2 border-b">{row[col]}</td>
+              ))}
+            </tr>
+          ))}
+        </tbody>
+      </table>
+    </div>
+  ),
+
+  text: ({ content, variant = 'body' }) => {
+    const className = {
+      heading: 'text-xl font-bold',
+      body: 'text-base',
+      caption: 'text-sm text-muted-foreground',
+    }[variant];
+    return <p className={className}>{content}</p>;
+  },
+};
+
+// Main renderer
+export function DashboardRenderer({
+  spec,
+  data = {},
+}: {
+  spec: Dashboard;
+  data?: Record<string, any>;
+}) {
+  const layoutClass = {
+    grid: `grid gap-4 ${spec.columns ? `grid-cols-${spec.columns}` : 'grid-cols-2'}`,
+    stack: 'flex flex-col gap-4',
+    tabs: 'space-y-4',
+  }[spec.layout];
+
+  return (
+    <div className={layoutClass}>
+      {spec.widgets.map((widget, index) => {
+        const Component = widgetComponents[widget.type];
+        if (!Component) {
+          console.warn(`Unknown widget type: ${widget.type}`);
+          return null;
+        }
+
+        // Resolve data references
+        const widgetData = widget.dataKey ? data[widget.dataKey] : undefined;
+
+        return (
+          <Component
+            key={index}
+            {...widget}
+            data={widgetData}
+          />
+        );
+      })}
+    </div>
+  );
+}
+```
+
+## 5. Generate LLM Prompts
+
+Use the catalog to generate system prompts for AI:
+
+```typescript
+const systemPrompt = dashboardCatalog.prompt({
+  customRules: [
+    'Use metric widgets for single KPI values',
+    'Use chart widgets for time-series data',
+    'Use table widgets for lists of records',
+    'Limit dashboards to 6 widgets maximum',
+  ],
+});
+
+// Use with any LLM
+const response = await generateText({
+  model: 'gpt-4',
+  system: systemPrompt,
+  prompt: 'Create a sales dashboard with revenue, orders, and a chart',
+});
+```
+
+## 6. Validate Specs
+
+Validate incoming specs against your schema:
+
+```typescript
+import { validate } from '@json-render/core';
+
+function validateDashboard(spec: unknown) {
+  // Validate root structure
+  const rootResult = DashboardSchema.safeParse(spec);
+  if (!rootResult.success) {
+    return { valid: false, errors: rootResult.error.errors };
+  }
+
+  // Validate each widget against catalog
+  const errors: string[] = [];
+  for (const widget of rootResult.data.widgets) {
+    const result = validate(
+      { type: widget.type, props: widget },
+      dashboardCatalog
+    );
+    if (!result.valid) {
+      errors.push(...result.errors.map(e => `${widget.type}: ${e}`));
+    }
+  }
+
+  return { valid: errors.length === 0, errors };
+}
+```
+
+## Usage Example
+
+```tsx
+'use client';
+
+import { useState } from 'react';
+import { DashboardRenderer } from './renderer';
+import type { Dashboard } from './schema';
+
+const initialSpec: Dashboard = {
+  layout: 'grid',
+  columns: 2,
+  widgets: [
+    { type: 'metric', title: 'Revenue', value: '$12,345', trend: 'up' },
+    { type: 'metric', title: 'Orders', value: '156', trend: 'up' },
+    { type: 'chart', title: 'Sales Trend', chartType: 'line', dataKey: 'sales' },
+    { type: 'table', title: 'Recent Orders', columns: ['id', 'customer', 'amount'], dataKey: 'orders' },
+  ],
+};
+
+const data = {
+  sales: [/* chart data */],
+  orders: [
+    { id: '001', customer: 'Acme Inc', amount: '$500' },
+    { id: '002', customer: 'Globex', amount: '$750' },
+  ],
+};
+
+export function MyDashboard() {
+  const [spec, setSpec] = useState(initialSpec);
+
+  return <DashboardRenderer spec={spec} data={data} />;
+}
+```

+export const metadata = { title: "Data Binding" }
+
+# Data Binding
+
+Connect UI components to your application data using JSON Pointer paths.
+
+## JSON Pointer Paths
+
+json-render uses JSON Pointer (RFC 6901) for data paths:
+
+```json
+// Given this data:
+{
+  "user": {
+    "name": "Alice",
+    "email": "alice@example.com"
+  },
+  "metrics": {
+    "revenue": 125000,
+    "growth": 0.15
+  }
+}
+
+// These paths access:
+"/user/name"        -> "Alice"
+"/metrics/revenue"  -> 125000
+"/metrics/growth"   -> 0.15
+```
+
+## StateProvider
+
+Wrap your app with StateProvider to enable data binding:
+
+```tsx
+import { StateProvider } from '@json-render/react';
+
+function App() {
+  const initialState = {
+    user: { name: 'Alice' },
+    form: { email: '', message: '' },
+  };
+
+  return (
+    <StateProvider initialState={initialState}>
+      {/* Your UI */}
+    </StateProvider>
+  );
+}
+```
+
+## Reading Data
+
+Use `useStateValue` for read-only access:
+
+```tsx
+import { useStateValue } from '@json-render/react';
+
+function UserGreeting() {
+  const name = useStateValue('/user/name');
+  return <h1>Hello, {name}!</h1>;
+}
+```
+
+## Two-Way Binding
+
+Use `useStateBinding` for read-write access:
+
+```tsx
+import { useStateBinding } from '@json-render/react';
+
+function EmailInput() {
+  const [email, setEmail] = useStateBinding('/form/email');
+  
+  return (
+    <input
+      type="email"
+      value={email || ''}
+      onChange={(e) => setEmail(e.target.value)}
+    />
+  );
+}
+```
+
+## Using the State Context
+
+Access the full state context for advanced use cases:
+
+```tsx
+import { useStateStore } from '@json-render/react';
+
+function StateDebugger() {
+  const { data, setState, getValue, setValue } = useStateStore();
+  
+  // Read any path
+  const revenue = getValue('/metrics/revenue');
+  
+  // Write any path
+  const updateRevenue = () => setValue('/metrics/revenue', 150000);
+  
+  // Replace all state
+  const resetState = () => setState({ user: {}, form: {} });
+  
+  return <pre>{JSON.stringify(data, null, 2)}</pre>;
+}
+```
+
+## In JSON UI Trees
+
+AI can reference data paths in component props:
+
+```json
+{
+  "type": "Metric",
+  "props": {
+    "label": "Total Revenue",
+    "valuePath": "/metrics/revenue",
+    "format": "currency"
+  }
+}

+
+## Why OpenAPI?
+
+OpenAPI specifications describe your API's endpoints, request bodies, and response schemas. By converting OpenAPI schemas to json-render specs, you can:
+
+- Automatically generate forms for API endpoints
+- Display API responses with type-aware rendering
+- Keep your UI in sync with your API schema
+- Let AI generate UIs that match your API contracts

+      description: 'Nested object group',
+      props: z.object({
+        name: z.string(),
+        label: z.string(),
+        description: z.string().optional(),
+        collapsible: z.boolean().optional(),
+      }),
+    },
+  },
+  actions: {
+    submit: {
+      description: 'Submit form to API endpoint',
+      params: z.object({ operationId: z.string() }),

+  },
+});

+
+## Convert OpenAPI Schema to Spec
+
+Transform OpenAPI schemas into json-render specs by recursively walking the schema properties and mapping each type to the corresponding catalog component. The converter handles nested objects, enums, arrays, and all primitive types.
+
+## Usage Example
+
+```tsx
+'use client';
+
+import { OpenAPIForm } from './openapi-form';
+import { operationToSpec } from './openapi-to-spec';
+
+// Your OpenAPI schema (typically loaded from your API)
+const createUserSchema = {
+  type: 'object',
+  required: ['email', 'name'],
+  properties: {
+    name: { type: 'string', description: "User's full name" },
+    email: { type: 'string', format: 'email', description: "User's email" },
+    age: { type: 'integer', minimum: 0, maximum: 150 },
+    role: { type: 'string', enum: ['admin', 'user', 'guest'], default: 'user' },
+  },
+};
+
+// Convert to spec
+const spec = operationToSpec(
+  'createUser',
+  'POST',
+  '/api/users',
+  createUserSchema,
+  'Create User',
+  'Add a new user to the system',
+);
+
+export function CreateUserForm() {
+  const handleSubmit = async (data: Record<string, unknown>) => {
+    const response = await fetch('/api/users', {
+      method: 'POST',
+      headers: { 'Content-Type': 'application/json' },
+      body: JSON.stringify(data),
+    });
+
+    if (response.ok) {
+      console.log('User created!');
+    }
+  };
+
+  return <OpenAPIForm spec={spec} onSubmit={handleSubmit} />;
+}
+```
+
+## Auto-generating from OpenAPI Document
+
+Load and parse an OpenAPI document to generate forms for all operations:
+
+```typescript
+import SwaggerParser from '@apidevtools/swagger-parser';
+import { operationToSpec } from './openapi-to-spec';
+
+export async function loadOpenAPISpecs(specUrl: string) {
+  const api = await SwaggerParser.dereference(specUrl);
+  const specs: Record<string, any> = {};
+
+  for (const [path, methods] of Object.entries(api.paths)) {
+    for (const [method, operation] of Object.entries(methods)) {
+      if (!operation.requestBody?.content?.['application/json']?.schema) continue;
+
+      const schema = operation.requestBody.content['application/json'].schema;
+      const operationId = operation.operationId || `${method}_${path.replace(/\//g, '_')}`;
+
+      specs[operationId] = operationToSpec(
+        operationId,
+        method,
+        path,
+        schema,
+        operation.summary,
+        operation.description,
+      );
+    }
+  }
+
+  return specs;
+}
+
+// Usage
+const specs = await loadOpenAPISpecs('https://api.example.com/openapi.json');
+// specs.createUser, specs.updateUser, etc.
+```

+# Introduction
+
+Predictable. Guardrailed. Fast. Let users generate dashboards, widgets, apps, and data visualizations from prompts.
+
+## What is json-render?
+
+json-render lets end users generate UI from natural language prompts — safely constrained to components you define. You set the guardrails: what components exist, what props they take, what actions are available. AI generates JSON that matches your schema, and your components render it natively.
+
+## Why json-render?
+
+### Guardrailed
+
+AI can only use components in your catalog. No arbitrary code generation.
+
+### Predictable
+
+JSON output matches your schema, every time. Actions are declared by name, you control what they do.
+
+### Fast
+
+Stream and render progressively as the model responds. No waiting for completion.
+
+## How it works
+
+1. Define the guardrails — what components, actions, and data bindings AI can use
+2. Users prompt — end users describe what they want in natural language
+3. AI generates JSON — output is always predictable, constrained to your catalog
+4. Render fast — stream and render progressively as the model responds

+# Quick Start
+
+Get up and running with json-render in 5 minutes.
+
+## 1. Define your catalog
+
+Create a catalog that defines what components AI can use:
+
+```typescript
+// lib/catalog.ts
+import { defineCatalog } from '@json-render/core';
+import { schema } from '@json-render/react';
+import { z } from 'zod';
+
+export const catalog = defineCatalog(schema, {
+  components: {
+    Card: {
+      props: z.object({
+        title: z.string(),
+        description: z.string().nullable(),
+      }),
+      slots: ["default"],
+      description: "Container card with optional title",
+    },
+    Button: {
+      props: z.object({
+        label: z.string(),
+        action: z.string().nullable(),
+      }),
+      description: "Clickable button that triggers an action",
+    },
+    Text: {
+      props: z.object({
+        content: z.string(),
+      }),
+      description: "Text paragraph",
+    },
+  },
+  actions: {
+    submit: {
+      params: z.object({ formId: z.string() }),
+      description: "Submit a form",
+    },
+    navigate: {
+      params: z.object({ url: z.string() }),
+      description: "Navigate to a URL",
+    },
+  },
+});
+```
+
+## 2. Define your components
+
+Use `defineRegistry` to map catalog types to React components. Each component receives type-safe `props`, `children`, and `onAction`:
+
+```tsx
+// lib/registry.tsx
+import { defineRegistry } from '@json-render/react';
+import { catalog } from './catalog';
+
+export const { registry } = defineRegistry(catalog, {
+  components: {
+    Card: ({ props, children }) => (
+      <div className="p-4 border rounded-lg">
+        <h2 className="font-bold">{props.title}</h2>
+        {props.description && (
+          <p className="text-gray-600">{props.description}</p>
+        )}
+        {children}
+      </div>
+    ),
+    Button: ({ props, onAction }) => (
+      <button
+        className="px-4 py-2 bg-blue-500 text-white rounded"
+        onClick={() => onAction?.({ name: props.action })}
+      >
+        {props.label}
+      </button>
+    ),
+    Text: ({ props }) => (
+      <p>{props.content}</p>
+    ),
+  },
+});
+```
+
+## 3. Create an API route
+
+Set up a streaming API route for AI generation:
+
+```typescript
+// app/api/generate/route.ts
+import { streamText } from 'ai';
+import { catalog } from '@/lib/catalog';
+
+export async function POST(req: Request) {
+  const { prompt } = await req.json();
+
+  // Generate system prompt from catalog
+  const systemPrompt = catalog.prompt();
+
+  const result = streamText({
+    model: 'anthropic/claude-haiku-4.5',
+    system: systemPrompt,
+    prompt,
+  });
+
+  return result.toTextStreamResponse();
+}
+```
+
+## 4. Render the UI
+
+Use providers and the `Renderer` with your registry to display AI-generated UI:
+
+```tsx
+// app/page.tsx
+'use client';
+
+import { Renderer, StateProvider, ActionProvider, VisibilityProvider, useUIStream } from '@json-render/react';
+import { registry } from '@/lib/registry';
+
+export default function Page() {
+  const { spec, isStreaming, send } = useUIStream({
+    api: '/api/generate',
+  });
+
+  const handleSubmit = (e: React.FormEvent<HTMLFormElement>) => {
+    e.preventDefault();
+    const formData = new FormData(e.currentTarget);
+    send(formData.get('prompt') as string);
+  };
+
+  return (
+    <StateProvider initialState={{}}>
+      <VisibilityProvider>
+        <ActionProvider handlers={{
+          submit: (params) => console.log('Submit:', params),
+          navigate: (params) => console.log('Navigate:', params),
+        }}>
+          <form onSubmit={handleSubmit}>
+            <input
+              name="prompt"
+              placeholder="Describe what you want..."
+              className="border p-2 rounded"
+            />
+            <button type="submit" disabled={isStreaming}>
+              Generate
+            </button>
+          </form>
+
+          <div className="mt-8">
+            <Renderer spec={spec} registry={registry} loading={isStreaming} />
+          </div>
+        </ActionProvider>

+# Registry
+
+Register React components and action handlers to bring your catalog to life.
+
+## defineRegistry
+
+Use `defineRegistry` to create a type-safe registry from your catalog. Pass your components, actions, or both in a single call:
+
+```tsx
+import { defineRegistry } from '@json-render/react';
+import { myCatalog } from './catalog';
+
+export const { registry, handlers, executeAction } = defineRegistry(myCatalog, {
+  components: {
+    Card: ({ props, children }) => (
+      <div className="card">
+        <h2>{props.title}</h2>
+        {props.description && <p>{props.description}</p>}
+        {children}
+      </div>
+    ),
+
+    Button: ({ props, onAction }) => (
+      <button onClick={() => onAction?.({ name: props.action })}>
+        {props.label}
+      </button>
+    ),
+  },
+
+  actions: {
+    submit_form: async (params, setState) => {
+      const res = await fetch('/api/submit', {
+        method: 'POST',
+        body: JSON.stringify(params),
+      });
+      const result = await res.json();
+      setState((prev) => ({ ...prev, formResult: result }));
+    },
+
+    export_data: async (params) => {
+      const blob = await generateExport(params.format);
+      downloadBlob(blob, `export.${params.format}`);
+    },
+  },
+});
+```
+
+The returned object contains:
+
+- `registry` - component registry for `<Renderer />`
+- `handlers` - factory for ActionProvider-compatible handlers
+- `executeAction` - imperative action dispatch (for use outside the React tree)
+
+## Component Props
+
+Each component in the registry receives a `ComponentContext` object:
+
+```typescript
+interface ComponentContext {
+  props: T;                    // Type-safe props from your catalog
+  children?: React.ReactNode;  // Rendered children (for slot components)
+  onAction?: (action: ActionTrigger) => void;  // Dispatch an action
+  loading?: boolean;           // Whether the renderer is in a loading state
+}
+```
+
+Props are automatically inferred from your catalog, so `props.title` is typed as `string` if your catalog defines it that way.
+
+## Action Handlers
+
+Instead of AI generating arbitrary code, it declares *intent* by name. Your application provides the implementation. This is a core guardrail.
+
+### Defining Actions
+
+Define available actions in your catalog:
+
+```typescript
+import { defineCatalog } from '@json-render/core';
+import { schema } from '@json-render/react';
+import { z } from 'zod';
+
+const catalog = defineCatalog(schema, {
+  components: { /* ... */ },
+  actions: {
+    submit_form: {
+      params: z.object({
+        formId: z.string(),
+      }),
+      description: 'Submit a form',
+    },
+    export_data: {
+      params: z.object({
+        format: z.enum(['csv', 'pdf', 'json']),
+      }),
+    },
+    navigate: {
+      params: z.object({
+        url: z.string(),
+      }),
+    },
+  },
+});
+```
+
+### Implementing Action Handlers
+
+Action handlers receive `(params, setState, data)` and are defined inside `defineRegistry`:
+
+```tsx
+export const { handlers, executeAction } = defineRegistry(catalog, {
+  actions: {
+    submit_form: async (params, setState) => {
+      const response = await fetch('/api/submit', {
+        method: 'POST',
+        body: JSON.stringify({ formId: params.formId }),
+      });
+      const result = await response.json();
+      setState((prev) => ({ ...prev, formResult: result }));
+    },
+
+    export_data: async (params) => {
+      const blob = await generateExport(params.format);
+      downloadBlob(blob, `export.${params.format}`);
+    },
+
+    navigate: (params) => {
+      window.location.href = params.url;
+    },
+  },
+});
+```
+
+## Using Data Binding
+
+Use hooks inside your registry components to read and write data:
+
+```tsx
+import { useStateStore } from '@json-render/react';
+import { getByPath } from '@json-render/core';
+
+// Inside defineRegistry components:
+
+Metric: ({ props }) => {
+  const { data } = useStateStore();
+  const value = getByPath(data, props.valuePath);
+
+  return (
+    <div className="metric">
+      <span className="label">{props.label}</span>
+      <span className="value">{formatValue(value)}</span>
+    </div>
+  );
+},
+
+TextField: ({ props }) => {
+  const { data, set } = useStateStore();
+  const value = getByPath(data, props.valuePath) as string;
+
+  return (
+    <input
+      value={value || ''}
+      onChange={(e) => set(props.valuePath, e.target.value)}
+      placeholder={props.placeholder}
+    />
+  );
+},
+```
+
+## Using the Renderer
+
+Wire everything together with providers and the `<Renderer />` component:
+
+```tsx
+import { useMemo, useRef } from 'react';
+import {
+  Renderer,
+  StateProvider,
+  VisibilityProvider,
+  ActionProvider,
+} from '@json-render/react';
+import { registry, handlers } from './registry';
+
+function App({ spec, data, setState }) {
+  const dataRef = useRef(data);
+  const setStateRef = useRef(setState);
+  dataRef.current = data;
+  setStateRef.current = setState;
+
+  const actionHandlers = useMemo(
+    () => handlers(() => setStateRef.current, () => dataRef.current),
+    [],
+  );
+
+  return (
+    <StateProvider initialState={data}>
+      <VisibilityProvider>
+        <ActionProvider handlers={actionHandlers}>
+          <Renderer spec={spec} registry={registry} />
+        </ActionProvider>
+      </VisibilityProvider>
+    </StateProvider>
+  );
+}
+```

+
+# Schemas
+
+Schemas define the structure and validation rules for your UI specs.
+
+## What is a Schema?
+
+A schema defines the JSON structure that describes your UI. It includes:
+
+- **Element structure** — How components are nested and referenced
+- **Property types** — What props each component accepts
+- **Data binding syntax** — How to reference dynamic data
+- **Action format** — How user interactions are defined
+
+## Schema-Agnostic by Design
+
+json-render can work with any JSON schema. `@json-render/core` provides the primitives to define catalogs and renderers for any format:
+
+- **@json-render/react** — The built-in flat element tree schema
+- **[A2UI](/docs/a2ui)** — Google's Agent-to-User Interaction protocol
+- **[Adaptive Cards](/docs/adaptive-cards)** — Microsoft's platform-agnostic UI format
+- **AG-UI** — CopilotKit's Agent User Interaction Protocol
+- **OpenAPI/Swagger** — API documentation schemas for dynamic forms
+- **Custom schemas** — Design your own format tailored to your domain
+
+See the [Custom Schema guide](/docs/custom-schema) to learn how to implement support for any schema.
+
+## Built-in Schema
+
+`@json-render/react` uses a flat element tree schema with a root key and elements map:
+
+```json
+{
+  "root": "card-1",
+  "elements": {
+    "card-1": {
+      "type": "Card",
+      "props": { "title": "Dashboard" },
+      "children": ["text-1", "button-1"]
+    },
+    "text-1": {
+      "type": "Text",
+      "props": { "content": "Welcome, $data.user.name" },
+      "children": []
+    },
+    "button-1": {
+      "type": "Button",
+      "props": { "label": "Click me" },
+      "children": []
+    }
+  }
+}
+```
+
+## Schema Components
+
+### Element Structure
+
+In the built-in schema, each element in the elements map has this structure:
+
+```typescript
+interface Element {
+  type: string;                // Component type from catalog
+  props: Record<string, any>;  // Component properties
+  children: string[];          // Array of child element keys
+  visible?: VisibilityRule;    // Conditional display
+}
+```
+
+### Data Binding Syntax
+
+Reference dynamic data using the `$data` prefix in props:
+
+```json
+{
+  "type": "Text",
+  "props": {
+    "content": "$data.user.name",
+    "count": "$data.items.length"
+  },
+  "children": []
+}
+```
+
+### Action Format
+
+Actions are defined in the catalog and referenced from components. The renderer handles action execution:
+
+```typescript
+// In your catalog
+actions: {
+  navigate: {
+    params: z.object({ url: z.string() }),
+    description: 'Navigate to a URL',
+  },
+  apiCall: {
+    params: z.object({
+      endpoint: z.string(),
+      method: z.enum(['GET', 'POST', 'PUT', 'DELETE']),
+    }),
+    description: 'Make an API request',
+  },
+}
+```
+
+## Custom Schemas
+
+`@json-render/core` is schema-agnostic. You can define any JSON structure:
+
+```typescript
+import { z } from 'zod';
+
+// Define your own element schema
+const MyElementSchema = z.object({
+  component: z.string(),
+  settings: z.record(z.unknown()),
+  nested: z.array(z.lazy(() => MyElementSchema)).optional(),
+});
+
+// Define your own data binding format
+const BoundValue = z.object({
+  literal: z.string().optional(),
+  path: z.string().optional(),  // e.g., "/users/0/name"
+});
+
+// Define your own action format
+const ActionSchema = z.object({
+  name: z.string(),
+  context: z.record(z.unknown()).optional(),
+});
+```
+
+## Schema vs Catalog
+
+The schema and catalog work together but serve different purposes:
+
+- **Schema** — Defines the JSON structure (how elements are organized)
+- **Catalog** — Defines available components and their props (what can be used)
+
+The schema is the grammar; the catalog is the vocabulary.
+

+
+# Specs
+
+A spec is a JSON document that describes your UI.
+
+## What is a Spec?
+
+A spec (specification) is the actual JSON that describes a UI. It conforms to a [schema](/docs/schemas) and uses components from a [catalog](/docs/catalog). Specs can be:
+
+- Generated by AI in real-time
+- Stored in a database
+- Streamed progressively from a server
+- Hand-authored as JSON files
+
+json-render is schema-agnostic — your specs can follow any JSON structure you choose.
+
+## Example Specs
+
+### Simple Spec
+
+A basic spec using the `@json-render/react` schema. Note the flat structure with a `root` key and `elements` map:
+
+```json
+{
+  "root": "card-1",
+  "elements": {
+    "card-1": {
+      "type": "Card",
+      "props": { "title": "Welcome" },
+      "children": ["text-1"]
+    },
+    "text-1": {
+      "type": "Text",
+      "props": { "content": "Hello, $data.user.name!" },
+      "children": []
+    }
+  }
+}
+```
+
+### Complex Spec
+
+A more complex spec with multiple nested elements:
+
+```json
+{
+  "root": "card-1",
+  "elements": {
+    "card-1": {
+      "type": "Card",
+      "props": { "title": "User Profile", "padding": "md" },
+      "children": ["row-1", "button-1"]
+    },
+    "row-1": {
+      "type": "Row",
+      "props": { "gap": "md" },
+      "children": ["avatar-1", "stack-1"]
+    },
+    "avatar-1": {
+      "type": "Avatar",
+      "props": { "src": "$data.user.avatar", "alt": "$data.user.name" },
+      "children": []
+    },
+    "stack-1": {
+      "type": "Stack",
+      "props": { "gap": "sm" },
+      "children": ["name-text", "email-text"]
+    },
+    "name-text": {
+      "type": "Text",
+      "props": { "content": "$data.user.name", "variant": "heading" },
+      "children": []
+    },
+    "email-text": {

+
+## Spec Anatomy
+
+### Root and Elements
+
+Every spec has a `root` key pointing to the entry element, and an `elements` map containing all elements:
+
+```json
+{
+  "root": "card-1",
+  "elements": {
+    "card-1": {
+      "type": "Card",
+      "props": { "title": "My Card" },
+      "children": ["text-1"]
+    },
+    "text-1": { ... }
+  }
+}
+```
+
+### Element Structure
+
+Each element in the map has a consistent shape:
+
+```json
+{
+  "type": "ComponentName",
+  "props": { "label": "Hello" },
+  "children": ["child-1", "child-2"]
+}
+```
+
+- `type` — Component type from your catalog
+- `props` — Component properties
+- `children` — Array of child element keys
+
+### Dynamic Data
+
+Props can reference data using `$data` paths:
+
+```json
+{
+  "type": "Metric",
+  "props": {
+    "label": "Total Revenue",
+    "value": "$data.metrics.revenue",
+    "change": "$data.metrics.revenueChange"
+  },
+  "children": []
+}
+```
+
+### Conditional Visibility
+
+Control when elements appear using the `visible` property:
+
+```json
+{
+  "type": "Alert",
+  "props": {
+    "message": "You have unsaved changes"
+  },
+  "children": [],
+  "visible": {
+    "path": "$data.form.isDirty",
+    "operator": "eq",
+    "value": true
+  }
+}
+```
+
+## Working with Specs
+
+### Rendering a Spec
+
+```tsx
+import { Renderer } from '@json-render/react';
+
+function MyApp({ spec, data }) {
+  return (
+    <Renderer
+      spec={spec}
+      data={data}
+      registry={registry}
+    />
+  );
+}
+```
+
+### Validating a Spec
+
+```typescript
+import { validate } from '@json-render/core';
+
+const result = validate(spec, catalog);
+
+if (!result.valid) {
+  console.error('Invalid spec:', result.errors);
+}
+```
+
+### Streaming Specs
+
+Specs can be streamed incrementally for progressive rendering:
+
+```tsx
+import { useUIStream } from '@json-render/react';
+
+function GenerativeUI() {
+  const { spec, isStreaming } = useUIStream({
+    api: '/api/generate',
+  });
+
+  return (
+    <Renderer
+      spec={spec}
+      registry={registry}
+      loading={isStreaming}
+    />
+  );
+}
+```
+
+## Spec Sources
+
+Specs can come from various sources:
+
+- **AI Generation** — LLMs generate specs based on prompts and catalog
+- **Database** — Store specs as JSON and load dynamically
+- **API Response** — Server returns specs based on user/context
+- **Static Files** — Pre-built specs for known UI patterns
+

+
+# Streaming
+
+Progressively render UI as AI generates it.
+
+## SpecStream Format
+
+json-render uses **SpecStream**, a JSONL-based streaming format where each line is a JSON patch operation that progressively builds your spec:
+
+```json
+{"op":"add","path":"/root","value":"root"}
+{"op":"add","path":"/elements/root","value":{"type":"Card","props":{"title":"Dashboard"},"children":["metric-1","metric-2"]}}
+{"op":"add","path":"/elements/metric-1","value":{"type":"Metric","props":{"label":"Revenue"}}}
+{"op":"add","path":"/elements/metric-2","value":{"type":"Metric","props":{"label":"Users"}}}
+```
+
+## useUIStream Hook
+
+The hook handles parsing and state management:
+
+```tsx
+import { useUIStream } from '@json-render/react';
+
+function App() {
+  const {
+    spec,          // Current UI spec state
+    isStreaming,   // True while streaming
+    error,         // Any error that occurred
+    send,          // Function to start generation
+    clear,         // Function to reset spec and error
+  } = useUIStream({
+    api: '/api/generate',
+    onComplete: (spec) => {},  // Optional: called when streaming completes
+    onError: (error) => {},    // Optional: called when an error occurs
+  });
+}
+```
+
+## Patch Operations (RFC 6902)
+
+SpecStream uses [RFC 6902 JSON Patch](https://datatracker.ietf.org/doc/html/rfc6902) operations:
+
+- `add` — Add a value at a path (creates or replaces for objects, inserts for arrays)
+- `remove` — Remove the value at a path
+- `replace` — Replace an existing value at a path
+- `move` — Move a value from one path to another (requires `from`)
+- `copy` — Copy a value from one path to another (requires `from`)
+- `test` — Assert that a value at a path equals the given value
+
+## Path Format
+
+Paths use a key-based format for elements:
+
+```bash
+/root              -> Root element
+/root/children     -> Children of root
+/elements/card-1   -> Element with key "card-1"
+/elements/card-1/children -> Children of card-1
+```
+
+## Server-Side Setup
+
+Ensure your API route streams properly:
+
+```typescript
+import { streamText } from 'ai';
+import { catalog } from '@/lib/catalog';
+
+export async function POST(req: Request) {
+  const { prompt } = await req.json();
+  
+  const result = streamText({
+    model: 'anthropic/claude-haiku-4.5',
+    system: catalog.prompt(),
+    prompt,
+  });
+
+  // Return as a streaming response
+  return result.toTextStreamResponse();
+}
+```
+
+## Progressive Rendering
+
+The Renderer automatically updates as the spec changes:
+
+```tsx
+function App() {
+  const { spec, isStreaming } = useUIStream({ api: '/api/generate' });
+
+  return (
+    <div>
+      {isStreaming && <LoadingIndicator />}
+      <Renderer spec={spec} registry={registry} loading={isStreaming} />
+    </div>
+  );
+}
+```
+
+## Aborting Streams
+
+Calling `send` again automatically aborts the previous request. Use `clear` to reset the spec and error state:
+
+```tsx
+function App() {
+  const { isStreaming, send, clear } = useUIStream({
+    api: '/api/generate',
+  });
+
+  return (
+    <div>
+      <button onClick={() => send('Create dashboard')}>
+        Generate
+      </button>
+      <button onClick={clear}>Reset</button>
+    </div>
+  );
+}
+```
+
+## Low-Level SpecStream API
+
+For custom streaming implementations, use the SpecStream compiler directly:
+
+```typescript
+import { createSpecStreamCompiler } from '@json-render/core';
+
+// Create a compiler for your spec type
+const compiler = createSpecStreamCompiler<MySpec>();
+
+// Process streaming chunks from AI
+async function processStream(reader: ReadableStreamDefaultReader) {
+  while (true) {
+    const { done, value } = await reader.read();
+    if (done) break;
+    
+    const { result, newPatches } = compiler.push(value);
+    
+    if (newPatches.length > 0) {
+      // Update UI with partial result
+      setSpec(result);
+    }
+  }
+  
+  // Get final compiled result
+  return compiler.getResult();
+}
+```
+
+### One-Shot Compilation
+
+For non-streaming scenarios, compile entire SpecStream at once:
+
+```typescript
+import { compileSpecStream } from '@json-render/core';
+
+const jsonl = `{"op":"add","path":"/root","value":{"type":"Card"}}
+{"op":"add","path":"/root/props","value":{"title":"Hello"}}`;
+
+const spec = compileSpecStream<MySpec>(jsonl);
+// { root: { type: "Card", props: { title: "Hello" } } }
+```

+
+# Validation
+
+Validate form inputs with built-in and custom functions.
+
+## Built-in Validators
+
+json-render includes common validation functions:
+
+- `required` — Value must be non-empty
+- `email` — Valid email format
+- `minLength` — Minimum string length
+- `maxLength` — Maximum string length
+- `pattern` — Match a regex pattern
+- `min` — Minimum numeric value
+- `max` — Maximum numeric value
+
+## Using Validation in JSON
+
+```json
+{
+  "type": "TextField",
+  "props": {
+    "label": "Email",
+    "valuePath": "/form/email",
+    "checks": [
+      { "fn": "required", "message": "Email is required" },
+      { "fn": "email", "message": "Invalid email format" }
+    ],
+    "validateOn": "blur"
+  }
+}
+```
+
+## Validation with Parameters
+
+```json
+{
+  "type": "TextField",
+  "props": {
+    "label": "Password",
+    "valuePath": "/form/password",
+    "checks": [
+      { "fn": "required", "message": "Password is required" },
+      { 
+        "fn": "minLength", 
+        "args": { "length": 8 },
+        "message": "Password must be at least 8 characters"
+      },
+      {
+        "fn": "pattern",

+        "message": "Must contain at least one uppercase letter"
+      }
+    ]
+  }
+}
+```
+
+## Custom Validation Functions
+
+Define custom validators in your catalog:
+
+```typescript
+import { defineCatalog } from '@json-render/core';
+import { schema } from '@json-render/react';
+import { z } from 'zod';
+
+const catalog = defineCatalog(schema, {
+  components: { /* ... */ },
+  functions: {
+    isValidPhone: {
+      description: 'Validates phone number format',
+    },
+    isUniqueEmail: {
+      description: 'Checks if email is not already registered',
+    },
+  },
+});
+```
+
+Then implement them in your ValidationProvider:
+
+```tsx
+import { ValidationProvider } from '@json-render/react';
+
+function App() {
+  const customValidators = {
+    isValidPhone: (value) => {
+      const phoneRegex = /^\+?[1-9]\d{1,14}$/;
+      return phoneRegex.test(value);
+    },
+    isUniqueEmail: async (value) => {
+      const response = await fetch(`/api/check-email?email=${value}`);
+      const { available } = await response.json();
+      return available;
+    },
+  };
+
+  return (
+    <ValidationProvider functions={customValidators}>
+      {/* Your UI */}
+    </ValidationProvider>
+  );
+}
+```
+
+## Using in Components
+
+```tsx
+import { useFieldValidation } from '@json-render/react';
+
+function TextField({ props }) {
+  const { value, setValue, errors, validate } = useFieldValidation(
+    props.valuePath,
+    props.checks
+  );
+
+  return (
+    <div>
+      <label>{props.label}</label>
+      <input
+        value={value || ''}
+        onChange={(e) => setValue(e.target.value)}
+        onBlur={() => validate()}
+      />
+      {errors.map((error, i) => (
+        <p key={i} className="text-red-500 text-sm">{error}</p>
+      ))}
+    </div>
+  );
+}
+```
+
+## Validation Timing
+
+Control when validation runs with `validateOn`:
+
+- `change` — Validate on every input change
+- `blur` — Validate when field loses focus
+- `submit` — Validate only on form submission

+Conditionally show or hide components based on data, auth, or logic.
+
+## VisibilityProvider
+
+Wrap your app with VisibilityProvider to enable conditional rendering:
+
+```tsx
+import { VisibilityProvider } from '@json-render/react';
+
+function App() {
+  return (
+    <StateProvider initialState={data}>
+      <VisibilityProvider>
+        {/* Components can now use visibility conditions */}

+    </StateProvider>
+  );
+}
+```
+
+## Path-Based Visibility
+
+Show/hide based on data values:
+
+```json
+{
+  "type": "Alert",
+  "props": { "message": "Form has errors" },
+  "visible": { "path": "/form/hasErrors" }
+}
+
+// Visible when /form/hasErrors is truthy
+```
+
+## Auth-Based Visibility
+
+Show/hide based on authentication state:
+
+```json
+{
+  "type": "AdminPanel",
+  "visible": { "auth": "signedIn" }
+}
+
+// Options: "signedIn", "signedOut", "admin", etc.
+```
+
+## Logic Expressions
+
+Combine conditions with logic operators:
+
+```json
+// AND - all conditions must be true
+{
+  "type": "SubmitButton",
+  "visible": {
+    "and": [
+      { "path": "/form/isValid" },
+      { "path": "/form/hasChanges" }
+    ]
+  }
+}
+
+// OR - any condition must be true
+{
+  "type": "HelpText",
+  "visible": {
+    "or": [
+      { "path": "/user/isNew" },
+      { "path": "/settings/showHelp" }
+    ]
+  }
+}
+
+// NOT - invert a condition
+{
+  "type": "WelcomeBanner",
+  "visible": {
+    "not": { "path": "/user/hasSeenWelcome" }
+  }
+}
+```
+
+## Comparison Operators
+
+```json
+// Equal
+{
+  "visible": {
+    "eq": [{ "path": "/user/role" }, "admin"]
+  }
+}
+
+// Greater than
+{
+  "visible": {
+    "gt": [{ "path": "/cart/total" }, 100]
+  }
+}
+
+// Available: eq, ne, gt, gte, lt, lte
+```
+
+## Complex Example
+
+```json
+{
+  "type": "RefundButton",
+  "props": { "label": "Process Refund" },
+  "visible": {
+    "and": [
+      { "auth": "signedIn" },

+      { "not": { "path": "/order/isRefunded" } }
+    ]
+  }
+}
+```
+
+## Using in Components
+
+```tsx
+import { useIsVisible } from '@json-render/react';
+
+// The Renderer handles visibility automatically, but you can also use the hook
+function ConditionalContent({ condition, children }) {
+  const isVisible = useIsVisible(condition);

-AVAILABLE COMPONENTS (22):
+const MAX_PROMPT_LENGTH = 500;
-
+const DEFAULT_MODEL = "anthropic/claude-haiku-4.5";
-Layout:
-- Card: { title?: string, description?: string, maxWidth?: "sm"|"md"|"lg"|"full", centered?: boolean } - Container card for content sections. Has children. Use for forms/content boxes, NOT for page headers.
-- Stack: { direction?: "horizontal"|"vertical", gap?: "sm"|"md"|"lg" } - Flex container. Has children.
-- Grid: { columns?: 2|3|4, gap?: "sm"|"md"|"lg" } - Grid layout. Has children. ALWAYS use mobile-first: set columns:1 and use className for larger screens.
-- Divider: {} - Horizontal separator line
-
-Form Inputs:
-- Input: { label: string, name: string, type?: "text"|"email"|"password"|"number", placeholder?: string } - Text input
-- Textarea: { label: string, name: string, placeholder?: string, rows?: number } - Multi-line text
-- Select: { label: string, name: string, options: string[], placeholder?: string } - Dropdown select
-- Checkbox: { label: string, name: string, checked?: boolean } - Checkbox input
-- Radio: { label: string, name: string, options: string[] } - Radio button group
-- Switch: { label: string, name: string, checked?: boolean } - Toggle switch
-
-Actions:
-- Button: { label: string, variant?: "primary"|"secondary"|"danger", actionText?: string } - Clickable button. actionText is shown in toast on click (defaults to label)
-- Link: { label: string, href: string } - Anchor link
-
-Typography:
-- Heading: { text: string, level?: 1|2|3|4 } - Heading text (h1-h4)
-- Text: { content: string, variant?: "body"|"caption"|"muted" } - Paragraph text
-
-Data Display:
-- Image: { src: string, alt: string, width?: number, height?: number } - Image
-- Avatar: { src?: string, name: string, size?: "sm"|"md"|"lg" } - User avatar with fallback initials
-- Badge: { text: string, variant?: "default"|"success"|"warning"|"danger" } - Status badge
-- Alert: { title: string, message?: string, type?: "info"|"success"|"warning"|"error" } - Alert banner
-- Progress: { value: number, max?: number, label?: string } - Progress bar (value 0-100)
-- Rating: { value: number, max?: number, label?: string } - Star rating display
-
-Charts:
-- BarGraph: { title?: string, data: Array<{label: string, value: number}> } - Vertical bar chart
-- LineGraph: { title?: string, data: Array<{label: string, value: number}> } - Line chart with points
-
-OUTPUT FORMAT (JSONL):
-{"op":"set","path":"/root","value":"element-key"}
-{"op":"add","path":"/elements/key","value":{"key":"...","type":"...","props":{...},"children":[...]}}
-
-ALL COMPONENTS support: className?: string[] - array of Tailwind classes for custom styling
-
-RULES:
-1. First line sets /root to root element key
-2. Add elements with /elements/{key}
-3. Children array contains string keys, not objects
-4. Parent first, then children
-5. Each element needs: key, type, props
-6. Use className for custom Tailwind styling when needed
-
-FORBIDDEN CLASSES (NEVER USE):
-- min-h-screen, h-screen, min-h-full, h-full, min-h-dvh, h-dvh - viewport heights break the small render container
-- bg-gray-50, bg-slate-50 or any page background colors - container already has background
-
-MOBILE-FIRST RESPONSIVE:
-- ALWAYS design mobile-first. Single column on mobile, expand on larger screens.
-- Grid: Use columns:1 prop, add className:["sm:grid-cols-2"] or ["md:grid-cols-3"] for larger screens
-- DO NOT put page headers/titles inside Card - use Stack with Heading directly
-- Horizontal stacks that may overflow should use className:["flex-wrap"]
-- For forms (login, signup, contact): Card should be the root element, NOT wrapped in a centering Stack
-
-EXAMPLE (Blog with responsive grid):
-{"op":"set","path":"/root","value":"page"}
-{"op":"add","path":"/elements/page","value":{"key":"page","type":"Stack","props":{"direction":"vertical","gap":"lg"},"children":["header","posts"]}}
-{"op":"add","path":"/elements/header","value":{"key":"header","type":"Stack","props":{"direction":"vertical","gap":"sm"},"children":["title","desc"]}}
-{"op":"add","path":"/elements/title","value":{"key":"title","type":"Heading","props":{"text":"My Blog","level":1}}}
-{"op":"add","path":"/elements/desc","value":{"key":"desc","type":"Text","props":{"content":"Latest posts","variant":"muted"}}}
