To write deterministic Native TypeScript scripts for Windmill, export a single async function named main and use the RT namespace for resources. Windmill handles execution and supplies resources, so you must not invoke the function directly.

No, you cannot use external imports in Windmill Native TypeScript scripts. This skill enforces a minimal, fetch-only execution environment, meaning you must use fetch for network calls and avoid all external module imports.

The RT namespace provides runtime resources to your Windmill scripts. Your async main function optionally receives credential and configuration data through this namespace, ensuring deterministic execution without relying on external imports.

You should not invoke the main function directly because Windmill drives execution and supplies resources automatically. Exporting the async main function creates a deterministic entry point that Windmill invokes at runtime.

The limitation of fetch-only Native TypeScript scripts in Windmill is that external imports are not allowed. You must rely entirely on fetch for network calls and the RT namespace for resources, restricting scripts to this minimal execution environment.
