responseFormat

Structured output response format for the subagent.

When specified, the subagent will produce a structuredResponse conforming to the given schema. The structured response is JSON-serialized and returned as the ToolMessage content to the parent agent, replacing the default last-message extraction.

Accepts any format supported by createAgent: Zod schemas, JSON schema objects, toolStrategy(schema), providerStrategy(schema), etc.

Copy
responseFormat: ResponseFormatInput<Record<string, any>>

Example

Copy
import { z } from "zod"

const analyzer: SubAgent = {
  name: "analyzer",
  description: "Analyzes data and returns structured findings",
  systemPrompt: "Analyze the data and return your findings.",
  responseFormat: z.object({
    findings: z.string(),
    confidence: z.number(),
  }),
};
