Drop into Claude / Cursor to get idiomatic Go code.
You're working with Go. Statically-typed language built for backend services at scale. Best practices: - Lean on: blazing fast - Lean on: great concurrency - Lean on: small binaries Things to watch for: - Watch out for: verbose error handling - Watch out for: no generics until recently General guidance: - Canonical docs: https://go.dev — check here before inventing APIs. - Keep secrets in environment variables, never commit them. - Write TypeScript where the ecosystem supports it; add types to every exported function. - Add tests for the critical paths before declaring the task done. - Read-the-docs is usually faster than guessing — cite the docs page in code comments when you apply a non-obvious pattern.

In one line: A compiled language built at Google for fast, concurrent backends.
Go (sometimes called Golang) is a compiled programming language — your code is turned into a single binary you can run anywhere. It's famously good for servers handling lots of connections at once.
