This Skill removes the friction of creating custom user experiences and API endpoints inside Apache Airflow by letting you extend the Airflow UI and backend in-process.
Tell the AI: Create an Airflow 3.1+ plugin that mounts a FastAPI endpoint at /my-plugin, serves a static UI from plugins/my-plugin/static/index.html, and adds a nav entry that links to an internal page at my-plugin/ui.

To embed a FastAPI app into the Airflow UI, build an Airflow 3.1+ plugin that mounts FastAPI endpoints directly inside the Airflow web process under a plugin URL prefix, eliminating the need for a separate backend service.
Yes, you can add custom navigation tabs and React pages to Airflow DAG, DAG run, task, and task instance views by registering external views within your Airflow 3.1+ plugin and serving the static React bundle assets directly through the integrated web server.
Airflow 3.1+ supports mounting FastAPI middleware inside plugins, allowing you to integrate custom middleware that interacts with Airflow APIs. You must avoid older Airflow 2 Flask and appbuilder patterns when implementing this in-process integration.
The best way to serve static assets from an Airflow plugin is to configure your plugin to host static files like HTML, JS, and CSS directly, ensuring you enforce relative href and fetch paths to maintain correct routing within the Airflow web process.
To handle blocking Airflow SDK or database calls in an async FastAPI plugin, you must offload those blocking operations using asyncio.to_thread, ensuring async safety and preventing the blocking of the Airflow web server's event loop.
Airflow 2 Flask and appbuilder patterns do not work in newer plugins because Airflow 3.1+ requires a different architecture that embeds FastAPI endpoints and custom UI components directly, moving away from legacy Flask-based extension methods.
