Go SDK

The Go SDK is the recommended default path when you want the strongest production contract.

• Open this area when you are building a production-oriented Go plugin.
• This is the best starting point when you want the least downstream runtime friction.
• If you are still choosing between Go, Python, and Node, start with /guide/what-you-can-build and /concepts/choosing-runtime.
