How are script arguments handled in this environment?

Arguments are passed to your script as positional parameters. You can access them using $1, $2, and so on. Note that all input arguments are treated as strings.

How do I deploy my script after writing it?

Use the command 'wmill script generate-metadata' to create the necessary .script.yaml and .lock files, followed by 'wmill sync push' to deploy it to your Windmill instance.

How do I return structured data to the Windmill workflow?

To return structured data, simply echo a valid JSON string to stdout. You can use heredocs (cat << EOF) or standard echo statements to output your results.

Why shouldn't I include a shebang in my Windmill Bash scripts?

Windmill handles the execution environment internally. Including #!/bin/bash is unnecessary and can interfere with the platform's script parsing and execution logic.

Automates the creation and deployment of Windmill-compatible Bash scripts with proper metadata and JSON handling.

This skill optimizes Claude for writing Bash scripts tailored specifically for the Windmill automation platform. It ensures scripts adhere to Windmill’s unique requirements, such as omitting the shebang, handling positional arguments as strings, and returning structured JSON data for workflow interoperability. By integrating Windmill CLI commands, it streamlines the development lifecycle from initial script creation and metadata generation to final deployment and resource management.
