Structured Output
When structured_output is set, the node returns a typed result instead of a plain text message.
Use a simplified inline schema - keys are field names, values are types.
A ? suffix on a key marks the field as optional.
kind: LLMNode
name: BookExtractor
prompts:
en:
system: Extract book information from the text.
structured_output:
title: str
author: str
year: int
genre: str
summary?: strSupported scalar types: str, int, float, bool.
In the short form, add a # comment on the line before a field to set its description.
The description is injected into the system prompt and the JSON schema sent to the LLM.
Multi-line comments are joined with a space into a single description string.
structured_output:
# The main title of the book as it appears on the cover
title: str
# The full name of the primary author, including first and last name
author: str
# The year the book was first published;
# use 0 when the year cannot be determined from the text
year: intFor more control, use the extended form. Each field becomes a mapping with type, description, and optional keys.
Comments are not read in this form - use description instead.
