agentsdk-go is a Go SDK specifically designed for agent development, aiming to address challenges developers face when building complex, scalable AI applications, such as tool integration, multi-model scheduling, security control, and runtime management.
This framework provides core runtime capabilities (e.g., Hooks, MCP, Sandbox, Skills, Sub-agents) and a four-point middleware interception layer, enabling developers to flexibly customize and extend agent behavior. By importing the SDK package and configuring models, tools, and rules, you can quickly build various AI applications ranging from CLI tools to enterprise-grade services.
It is well-suited for developers who need deep customization of AI workflows, integration of diverse external tools (via MCP), or building high-concurrency, observable agent systems within a Go technology stack. Whether you are a full-stack engineer, agent developer, or DevOps engineer, you can leverage its modular design to enhance development efficiency.
Before use, it is recommended to have a basic familiarity with Go and carefully review the upgrade guide to handle breaking changes in v2. For production environments, make full use of its security hooks, concurrency controls, and OpenTelemetry tracing capabilities to ensure system stability.
Key Features
Compared to similar SDKs, it natively integrates a Claude Code-style core runtime (e.g., automatic compression, security hooks) and provides a unique four-point middleware interception mechanism, allowing fine-grained control at key points in the request/response lifecycle. Additionally, its thread-safe runtime design and session-based mutex mechanisms offer out-of-the-box support for high-concurrency scenarios.
Limitations
Not suitable for teams unfamiliar with Go or those preferring to use more popular AI ecosystem languages like Python or JavaScript for rapid prototyping.
FAQ
How can I quickly get started with agentsdk-go?
After cloning the repository, run `make check` to ensure the environment is set up correctly, then refer to the minimal example in `examples/01-basic`.
Which AI models does it support?
It supports Anthropic Claude and OpenAI-compatible models via the `ModelFactory` interface, with binding possible at the sub-agent level.
