the language

outputs

The workflow's return value · symmetric to inputs. Each entry is a `${{ tasks.X.output }}` reference (untyped form · string) OR a typed declaration { value · type · description }. Powers `nika run` result + the output half of the callable-workflow schema. One of 59 words the served contract declares, projected from workflow.schema.json, the same file your editor validates against.

the contract

1 declaration

Descriptions are the schema's own; the deeper invariants (value languages and regexes) ride the same projection. A miss is a nika check finding before anything runs.
