If you want to persist feedback-submitted state in memory after ingestion, use the helper on the returned feedback object: |
```ts |
const feedbackId = "feedback-id-from-ingestion-response"; // returned by your feedback ingestion API response |
if (result.feedback && !result.feedback.isProvided()) { |
await result.feedback.markFeedbackProvided({ |
feedbackId, // optional |
}); |
} |
``` |
Use this helper only for memory-backed conversations (requests that include `userId` and `conversationId`). If those IDs are missing, messages are not persisted, so there is nothing to mark as provided. |
### Use a registered key |
If the key is already registered, you can omit `feedbackConfig` and the stored config is used. |
```ts |
const result = await agent.generateText("How was the answer?", { |
feedback: { key: "satisfaction" }, |
}); |
``` |
### Streaming feedback metadata |
For streaming, VoltAgent attaches feedback metadata to the stream wrapper returned by `agent.streamText`. The `onFinish` callback receives the underlying AI SDK `StreamTextResult`, which does not include VoltAgent feedback metadata. Read feedback from the returned stream wrapper after the stream completes. |
```ts |
const stream = await agent.streamText("Explain this trace", { |
feedback: true, |
onFinish: async (result) => { |
// result is the AI SDK StreamTextResult (no VoltAgent feedback here) |
console.log(await result.text); |
}, |
}); |
for await (const _chunk of stream.textStream) { |
// consume stream output |
} |
console.log(stream.feedback); |
``` |
## Automated feedback with eval scorers |
You can run LLM or heuristic scorers and persist the result as feedback without manual `fetch` calls. The `onResult` callback receives a `feedback` helper with `feedback.save(...)`. The `key` is required and the trace id is taken from the scorer result. |
```ts |
import { Agent, buildScorer } from "@voltagent/core"; |
import { openai } from "@ai-sdk/openai"; |
import { z } from "zod"; |
const judgeAgent = new Agent({ |
name: "satisfaction-judge", |
model: openai("gpt-4o-mini"), |
instructions: "Return JSON with score (0-1), label, and optional reason.", |
}); |
const judgeSchema = z.object({ |
score: z.number().min(0).max(1), |
label: z.string(), |
reason: z.string().optional(), |
}); |
const satisfactionScorer = buildScorer({ |
id: "satisfaction-judge", |
label: "Satisfaction Judge", |
}) |
.score(async ({ payload }) => { |
const prompt = `Score user satisfaction (0-1) and label it. |
User: ${payload.input} |
Assistant: ${payload.output}`; |
const response = await judgeAgent.generateObject(prompt, judgeSchema); |
return { |
score: response.object.score, |
metadata: { |
label: response.object.label, |
reason: response.object.reason ?? null, |
}, |
}; |
}) |
.build(); |
const agent = new Agent({ |
name: "support-agent", |
model: openai("gpt-4o-mini"), |
eval: { |
scorers: { |
satisfaction: { |
scorer: satisfactionScorer, |
onResult: async ({ result, feedback }) => { |
await feedback.save({ |
key: "satisfaction", |
value: result.metadata?.label ?? null, |
score: result.score ?? null, |
comment: result.metadata?.reason ?? null, |
feedbackSourceType: "model", |
