How does session forking work in this SDK?

Session forking allows you to create a new branch from an existing session ID. This lets you test different prompts or strategies without affecting the state of the original conversation.

Can I control which tools the agent is allowed to use?

Yes, the SDK provides a 'canUseTool' callback where you can programmatically allow, deny, or ask for user permission based on the tool name and its specific input arguments.

What are structured outputs in the Claude Agent SDK?

Structured outputs allow you to define a specific JSON schema that Claude must follow, ensuring the AI's response matches your expected data structure for reliable programmatic use.

What is the benefit of using MCP servers with the Claude Agent SDK?

Model Context Protocol (MCP) servers allow your agent to interact with external tools and data sources like filesystems, Git repositories, or remote APIs using a standardized communication protocol.

Developer Tools

Empowers developers to build autonomous AI agents with guaranteed structured JSON outputs and sophisticated plugin architectures.

The Claude Agent SDK skill provides a comprehensive framework for creating advanced, production-grade AI agents within the Claude Code environment. By leveraging the latest SDK capabilities (v0.1.45+), it enables strict JSON schema validation via Zod, ensuring that agent responses are type-safe and deterministic. This skill is ideal for building specialized agents such as security auditors, SRE systems, and complex coding assistants, offering features like session forking for alternative path exploration, custom hooks for event-driven workflows, and seamless integration with Model Context Protocol (MCP) servers.
