What Is an Action Input Default?
An action input default is a value declared in an action's metadata that applies when a workflow calls the action without supplying that input. It lets actions expose many options while keeping common usage terse. Callers override it only when they need a non-default behavior.
Why it matters
Sensible defaults make an action usable with minimal configuration while still allowing fine control. They also define behavior that is easy to overlook, so an unexpected result often traces back to a default the caller did not realize was active. Reading the defaults is part of understanding an action's contract.
