CLI Commands

Place scripts in a folder. After writing, tell the user they can run:

• wmill script generate-metadata - Generate .script.yaml and .lock files
• wmill sync push - Deploy to Windmill

Do NOT run these commands yourself. Instead, inform the user that they should run them.

Use wmill resource-type list --schema to discover available resource types.

@{
    name = $Name
    count = $Count
    age = $Age
