This toolkit accelerates the development of Claude-powered agents by providing utilities for session management, message parsing, and real-time communication. It targets developers building applications with Anthropic's AI models, offering patterns and examples to streamline the integration process and reduce boilerplate code.

How It Works

The Claude Agent Kit is a modular collection of npm packages built around the @anthropic-ai/claude-agent-sdk. It abstracts the complexities of managing agent sessions, handling streaming message payloads, and orchestrating real-time WebSocket communication. Key components include SessionManager for lifecycle control, Session for state tracking and SDK interaction, and WebSocketHandler for bridging client-server communication. The architecture supports persistence through JSONL logs and allows for extensibility in transport layers and SDK client implementations.

Quick Start & Requirements

• Installation: Run pnpm install and pnpm run build.
• Prerequisites: A Node.js or Bun environment is required. An ANTHROPIC_API_KEY environment variable must be set.
• Dependencies: The package currently targets @anthropic-ai/claude-agent-sdk@^0.1.0; users may need to adjust the version in package.json.
• Examples: Runnable examples are available in examples/basic-example (Bun WebSocket) and examples/claude-code-web (Express + Vite + ws).

Highlighted Details

• Provides session lifecycle helpers for synchronizing local state with Claude.
• Includes message parsing utilities to normalize and coalesce Claude streaming payloads.
• Offers WebSocket orchestration for building multi-client, real-time agent experiences.
• Features two distinct examples demonstrating integration patterns for different stack choices.
• Supports session persistence by reading/writing transcripts from .claude/projects JSONL logs.

Limitations & Caveats

The toolkit is explicitly tied to @anthropic-ai/claude-agent-sdk@^0.1.0, requiring manual version adjustments for compatibility with other SDK releases. The provided documentation does not detail performance benchmarks or extensive testing beyond unit tests.
