Description

A Python framework that wraps claude-code-sdk to provide better developer experience through decorator-based tools, runtime isolation, and simplified agent development. Built for production safety with Docker containers that ensure controlled tool execution and consistent behavior across all environments.

Comparison Table

Feature	claude-code-sdk	Claude Agent Toolkit
Custom Tools	Manual schema definition, No parallel execution support	Simple and intuitive class-based definition with @tool decorator, Built-in parallel execution with parallel=True
Runtime Isolation	No built-in isolation You need to design your own	Docker by default Allows only tools you explicitly added
Environment Consistency	Manual environment setup Explicit tool/option configuration required	Zero setup needed Works out of the box
Setup Complexity	~20 lines just for ClaudeCodeOptions configuration	~25 lines for complete agent with calculator Agent.run(verbose=True) shows all responses
Built-in Tools	Build everything from scratch	FileSystemTool with permission control DataTransferTool for formatted output handling
Best For	Using Claude Code as-is Minimal dependencies only	Fast development Using Claude Code as reasoning engine (like LangGraph agents)

thanks @cheolwanpark ! Looks like a very tidy toolkit. I don't use the python sdk much, and one thing that caught my eye was that it didn't seem that complicated based on the examples I saw regarding custom tools, and then also you mention this yourself in the README:

Update: Recent updates to claude-code-sdk have simplified tool addition significantly. This has substantially reduced the necessity for Claude Agent Toolkit compared to when it was first created.

/request-changes maybe you can clarify a little what the unique value of this resource is, or perhaps "pivot" it a little to more of the Docker stuff? I see the comments about when to use it, etc., but it kinda seems like you admit it doesn't add that much after recent developments, so curious to hear your thoughts. Thanks for sending this.

Thanks for the kind feedback, @hesreallyhim! I’ve updated the issue and the README.md in the repository - you only need to check the updated issue.

For a moment, I thought, “Wait, is my toolkit useless after the claude-code-sdk update? 😱” But now I’m convinced that my toolkit actually provides a better developer experience than using the raw claude-code-sdk directly.

Right now, I’m building a code snippet extraction/RAG tool for coding agents with this toolkit. The snippet extraction agent ended up being under 200 lines of code and is really stable. Achieving the same with the raw SDK would have been more complex and much harder to stabilize. In fact, my previous experience with claude-code-sdk was a total disaster of random actions caused by external configuration, since Claude Code automatically inherits the user’s configuration.

This toolkit helps developers build claude-code-sdk–based tools with minimal effort.
