Can I manage costs while using the SDK?

Yes, the SDK provides built-in cost tracking per-step and per-model, and allows you to set maxBudgetUsd and maxTurns limits.

What is the Claude Agent SDK?

It is Anthropic's framework for building autonomous AI agents, providing the same tools and agent loop that power Claude Code as a library.

Does this skill support Python projects?

Yes, this skill covers the complete API for both TypeScript (via @anthropic-ai/claude-agent-sdk) and Python (via claude-agent-sdk).

How can I define custom tools for my agent?

You can define custom tools as in-process MCP servers using the createSdkMcpServer function or connect to external servers via stdio, SSE, or HTTP.

What are agent hooks used for?

Hooks allow you to intercept and modify agent behavior at 16 different event points, such as before tool execution, during session starts, or before context compaction.

Data Science & ML

Enables developers to programmatically build, design, and orchestrate autonomous AI agents using the Claude Agent SDK.

This skill empowers developers to integrate the power of Claude's autonomous agent loop directly into their own applications. It provides comprehensive support for the Claude Agent SDK (formerly Claude Code SDK), allowing for the creation of custom tools via MCP, complex multi-agent orchestrations, and robust session management across both TypeScript and Python. Whether you are building a simple command-line utility or a sophisticated multi-turn AI system, this skill provides the necessary patterns for hooks, permissions, and cost tracking to ensure secure and efficient agent behavior.
