VoltAgent

Choose a setup method

Method	Use it when
Agnost AI skill	You want your coding agent to inspect the app, make the change, and verify it.
Agnost AI SDK	You want explicit control over the interaction boundaries and fields.
OpenTelemetry	The framework already emits useful spans or you operate an OTel pipeline.

Start with one method for a call path. Combining SDK tracking with framework OpenTelemetry on the same call can create duplicate interactions.

Recommended: Agnost AI skill

Recommended. Choose this path when you want your coding agent to inspect the project, select a supported transport, make the smallest instrumentation change, send a test event, and verify that it reached Agnost AI.

Install the skill once in your coding-agent environment:

npx skills add AgnostAI/skills --skill agnost-ai

Run the framework-specific prompt below from the application root. Review the resulting diff before deploying it.

Use the agnost-ai skill to add Agnost AI analytics to this VoltAgent application.
Org ID: your-org-id
Instrument the real agent.generateText() path and verify one fresh interaction.

Manual setup: Agnost AI SDK

npm install agnostai

import * as agnost from 'agnostai';

agnost.init('your-org-id');
const interaction = agnost.begin({ userId: 'u-42', agentName: 'voltagent-support', input: prompt });
try {
  const result = await agent.generateText(prompt);
  interaction.end(result.text);
} catch (error) {
  interaction.end(String(error), false);
  throw error;
} finally {
  await agnost.shutdown();
}

Manual setup: OpenTelemetry

VoltAgent ships its own observability layer. Plug an OTLP exporter into VoltAgentObservability, then pass userId / conversationId per call.

1. Install

Already have @voltagent/core and @opentelemetry/exporter-trace-otlp-proto? Skip. No setup yet?

npm install @voltagent/core @opentelemetry/exporter-trace-otlp-proto @opentelemetry/sdk-trace-node

2. Wire the OTel exporter pointing at Agnost AI

Already have VoltAgentObservability? Append a span processor for Agnost AI to the existing spanProcessors array:

import { OTLPTraceExporter } from '@opentelemetry/exporter-trace-otlp-proto';
import { BatchSpanProcessor } from '@opentelemetry/sdk-trace-node';

const agnostProcessor = new BatchSpanProcessor(
  new OTLPTraceExporter({
    url: 'https://otel.agnost.ai/v1/traces',
    headers: { 'X-Agnost-Org-ID': process.env.AGNOST_ORG_ID! },
  }),
);

// Inside your existing VoltAgentObservability:
spanProcessors: [
  // ...your existing processors,
  agnostProcessor,
]

No Observability yet? Full setup:

import { VoltAgent, VoltAgentObservability } from '@voltagent/core';
import { OTLPTraceExporter } from '@opentelemetry/exporter-trace-otlp-proto';
import { BatchSpanProcessor } from '@opentelemetry/sdk-trace-node';

const exporter = new OTLPTraceExporter({
  url: 'https://otel.agnost.ai/v1/traces',
  headers: { 'X-Agnost-Org-ID': process.env.AGNOST_ORG_ID! },
});

const observability = new VoltAgentObservability({
  spanProcessors: [new BatchSpanProcessor(exporter)],
});

new VoltAgent({ agents: { agent }, observability });

3. Pass userId / conversationId per call

await agent.generateText('Hello', {
  userId: 'user-42',
  conversationId: 'conv-abc123',
});

VoltAgent maps userId → user.id and conversationId → conversation.id on every span: both read directly by Agnost AI for user / session grouping.

What appears in Agnost AI

Conversations grouped by conversationId.
User-level analytics grouped by userId.
Events for every exported span.

Verify

Run one agent.generateText call, then open Events and confirm the span arrived.
