Fields

name: String

kind: ArgKind

doc: String

prompt: String

default: ArgDefault

completion: Option<String>

A registered COMPLETION source (gen:files, …) — inline candidates as the user types this argument.

picker: Option<String>

YR.6: a registered PICKER source offered for this argument.

Two fields because they name two registries, which is a decision rather than an oversight: a completion source is engine-shaped, a picker source is surface-shaped and needs PickerContext. An argument may set both — <Tab> completes inline, <C-x><C-o> opens the picker on the same question.
