+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Before completing any task
+
+Always run these commands before committing or saying a task is done:
+
+```bash
+bun run format
+bun run lint
+bunx tsc --noEmit
+bun run build
+bun test
+```
+
+No exceptions.
+
+## Project Overview
+
+**scrapegraph-js** is the official JavaScript/TypeScript SDK for the ScrapeGraph AI API. It provides a TypeScript client for intelligent web scraping powered by AI.

+## Tech Stack
+
+- **Language**: TypeScript (Node.js 22+)
+- **Runtime**: Bun
+- **Core Dependencies**: zod (validation)
+- **Testing**: Bun test
+- **Code Quality**: Biome (lint + format)
+- **Build**: tsup
+
+## Commands
+
+```bash
+# Install
+bun install
+
+# Dev (watch mode)
+bun run dev
+
+# Test
+bun test                    # unit tests
+bun run test:integration    # integration tests
+
+# Format
+bun run format
+
+# Lint
+bun run lint
+
+# Type check
+bunx tsc --noEmit
+
+# Build
+bun run build
+
+# Playground (loads .env)
+bun run playground
+```
+
+## Architecture
+
+**Core Components:**
+
+1. **Client** (`src/scrapegraphai.ts`):
+   - `ScrapeGraphAI()` - Factory function returning namespaced client
+   - Handles all API communication
+
+2. **Types** (`src/types.ts`):
+   - Request/response types for all endpoints
+   - Zod schema inference
+
+3. **Schemas** (`src/schemas.ts`):
+   - Zod validation schemas
+
+4. **Config** (`src/env.ts`):
+   - Environment variable handling
+
+## API Methods
+
+| Method | Purpose |
+|--------|---------|
+| `sgai.scrape()` | AI data extraction from URL |
+| `sgai.extract()` | Extract from raw HTML/text |
+| `sgai.search()` | Web search + extraction |
+| `sgai.crawl.start()` | Start crawl job |
+| `sgai.crawl.get()` | Get crawl status |
+| `sgai.monitor.create()` | Create monitoring job |
+| `sgai.monitor.get()` | Get monitor status |
+| `sgai.monitor.update()` | Update monitor config |
+| `sgai.monitor.delete()` | Delete monitor |
+| `sgai.credits()` | Check API credits |
+| `sgai.healthy()` | Health check |
+| `sgai.history.list()` | List request history |
+| `sgai.history.get()` | Get specific request |
+
+## Adding New Endpoint
+
+1. Add types in `src/types.ts`
+2. Add Zod schema in `src/schemas.ts`
+3. Add function in `src/scrapegraphai.ts`
+4. Wire into `ScrapeGraphAI()` client object
+5. Export types in `src/index.ts`
+6. Add tests in `tests/`
+7. Add example in `examples/`
+
+## Environment Variables
+
+- `SGAI_API_KEY` - API key for authentication
+- `SGAI_DEBUG` - Enable debug logging (optional)
+
+## Usage
+
+```typescript
+import { ScrapeGraphAI } from "scrapegraph-js";
+
+const sgai = ScrapeGraphAI(); // reads SGAI_API_KEY from env
+
+const res = await sgai.scrape({
+  url: "https://example.com",
+  prompt: "Extract the main heading",
+});
+
+if (res.status === "success") {
+  console.log(res.data?.result);
+}
+```
