What is authoring-go-sdk-tasks?

Writes Airflow task logic in Go using the Airflow Go SDK. Use when the user wants to implement Airflow tasks in Go, asks about `BundleProvider`/`RegisterDags`, the `bundlev1` Registry/Dag interfaces, registering Go tasks (`AddTask`/`AddTaskWithName`), dependency injection by parameter type (`context.Context`, `sdk.TIRunContext`, `*slog.Logger`, `sdk.Client`), or reading connections/variables/XComs from Go. This skill covers the Go-specific native API; the shared Python-stub pattern and conceptual model live in authoring-language-sdk-tasks. For building/packing/shipping the bundle see deploying-go-sdk-bundles; for coordinator config see configuring-airflow-language-sdks.

Authoring Go SDK Tasks

The Airflow Go SDK implements the language-SDK model for Go: your DAG stays in Python, and each task is a compiled Go function registered inside a bundle (a single native executable). This skill covers the Go-specific native API. The shared model (the Python @task.stub pattern, ID matching, the XCom-as-JSON contract) lives in authoring-language-sdk-tasks; read that first if you are new to language SDKs.

Experimental. The Go SDK is under active development and not production-ready. Module path github.com/apache/airflow/go-sdk (Go 1.24+). APIs may change.

Related skills: authoring-language-sdk-tasks (shared Python stub + concepts), deploying-go-sdk-bundles (build, pack, and ship the bundle), configuring-airflow-language-sdks (route the queue to the Go coordinator).

Recap: the Python side

A Go task is paired with a Python stub that carries no logic; it declares the task, its queue, and the dependency graph. IDs must match the Go registration exactly, and queue= routes the task to the Go runtime. Full rules are in authoring-language-sdk-tasks; the minimal shape:

from airflow.sdk import dag, task


@task.stub(queue="golang")
