+**WebAssembly bindings for Tiny Dancer neural routing.**
+
+`ruvector-tiny-dancer-wasm` brings production-grade AI agent routing to the browser with WebAssembly. Run FastGRNN neural inference for intelligent request routing directly in client-side applications. Part of the [Ruvector](https://github.com/ruvnet/ruvector) ecosystem.
+
+## Why Tiny Dancer WASM?
+
+- **Browser Native**: Run neural routing in any browser
+- **Low Latency**: Sub-millisecond inference times
+- **Small Bundle**: Optimized WASM binary (~100KB gzipped)
+- **Offline Capable**: No server required for inference
+- **Privacy First**: Route decisions stay client-side
+
+## Features
+
+### Core Capabilities
+
+- **Neural Inference**: FastGRNN model execution
+- **Feature Engineering**: Request feature extraction
+- **Multi-Agent Routing**: Score and rank agent candidates
+- **Model Loading**: Load pre-trained models
+- **Batch Inference**: Process multiple requests
+
+### Advanced Features
+
+- **Web Workers**: Background inference threads
+- **Streaming**: Process streaming requests
+- **Model Caching**: IndexedDB model persistence
+- **Quantization**: INT8 models for smaller size
+- **SIMD**: Hardware acceleration when available
+
+## Installation
+
+```bash
+npm install @ruvector/tiny-dancer-wasm
+# or
+yarn add @ruvector/tiny-dancer-wasm
+```
+
+## Quick Start
+
+### Basic Usage
+
+```typescript
+import init, { TinyDancer, RouteRequest } from '@ruvector/tiny-dancer-wasm';
+
+// Initialize WASM module
+await init();
+
+// Create router instance
+const router = new TinyDancer();
+
+// Load pre-trained model
+await router.loadModel('/models/router-v1.bin');
+
+// Create routing request
+const request: RouteRequest = {
+  query: "What is the weather like today?",
+  context: {
+    userId: "user-123",
+    sessionLength: 5,
+    previousAgent: "general",
+  },
+  agents: ["weather", "general", "calendar", "search"],
+};
+
+// Get routing decision
+const result = await router.route(request);
+console.log(`Route to: ${result.agent} (confidence: ${result.confidence})`);
+```
+
+### With Web Workers
+
+```typescript
+import { TinyDancerWorker } from '@ruvector/tiny-dancer-wasm/worker';
+
+// Create worker-based router (non-blocking)
+const router = new TinyDancerWorker();
+
+// Initialize in background
+await router.init();
+await router.loadModel('/models/router-v1.bin');
+
+// Route without blocking main thread
+const result = await router.route(request);
+```
+
+### Feature Engineering
+
+```typescript
+import { FeatureExtractor } from '@ruvector/tiny-dancer-wasm';
+
+const extractor = new FeatureExtractor();
+
+// Extract features from request
+const features = extractor.extract({
+  query: "Book a flight to Paris",
+  tokens: 6,
+  language: "en",
+  sentiment: 0.7,
+  entities: ["Paris"],
+});
+
+console.log(`Feature vector: ${features.length} dimensions`);
+```
+
+## API Reference
+
+### TinyDancer Class
+
+```typescript
+class TinyDancer {
+  constructor();
+
+  // Model management
+  loadModel(url: string): Promise<void>;
+  loadModelFromBuffer(buffer: Uint8Array): void;
+
+  // Routing
+  route(request: RouteRequest): Promise<RouteResult>;
+  routeBatch(requests: RouteRequest[]): Promise<RouteResult[]>;
+
+  // Scoring
+  scoreAgents(request: RouteRequest): Promise<AgentScore[]>;
+
+  // Info
+  getModelInfo(): ModelInfo;
+  isReady(): boolean;
+}
+```
+
+### Types
+
+```typescript
+interface RouteRequest {
+  query: string;
+  context?: Record<string, any>;
+  agents: string[];
+  constraints?: RouteConstraints;
+}
+
+interface RouteResult {
+  agent: string;
+  confidence: number;
+  scores: Record<string, number>;
+  latencyMs: number;
+}
+
+interface AgentScore {
+  agent: string;
+  score: number;
+  features: number[];
+}
+
+interface RouteConstraints {
+  excludeAgents?: string[];
+  minConfidence?: number;
+  timeout?: number;
+}
+```
+
+## Bundle Optimization
+
+### Tree Shaking
+
+```typescript
+// Import only what you need
+import { TinyDancer } from '@ruvector/tiny-dancer-wasm/core';
+import { FeatureExtractor } from '@ruvector/tiny-dancer-wasm/features';
+```
+
+### CDN Usage
+
+```html
+<script type="module">
+  import init, { TinyDancer } from 'https://unpkg.com/@ruvector/tiny-dancer-wasm';
+
+  await init();
+  const router = new TinyDancer();
+</script>
+```
+
+## Performance
+
+### Benchmarks (Chrome 120, M1 Mac)
+
+```
+Operation           Latency (p50)
+────────────────────────────────
+Model load          ~50ms
+Single inference    ~0.5ms
+Batch (10)          ~2ms
+Feature extraction  ~0.1ms
+```
+
+### Bundle Size
+
+```
+Format              Size
+────────────────────────
+WASM binary         ~100KB gzipped
+JS glue             ~5KB gzipped
+Total               ~105KB gzipped
+```
