# Raindrop

Instrumentation integration for eve. Send agent traces to Raindrop to detect and debug AI product issues.

## Install

Add Raindrop instrumentation from eve's registry. Raindrop ingests OTLP directly:

```bash
eve add instrumentation/raindrop
```

## Quick start

Create `agent/instrumentation.ts` and send traces to Raindrop's OTLP endpoint with your write key:

```ts
// agent/instrumentation.ts
import { defineInstrumentation } from "eve/instrumentation";
import { OTLPHttpProtoTraceExporter, registerOTel } from "@vercel/otel";

export default defineInstrumentation({
  setup: ({ agentName }) =>
    registerOTel({
      serviceName: agentName,
      traceExporter: new OTLPHttpProtoTraceExporter({
        url: "https://api.raindrop.ai/v1/traces",
        headers: {
          Authorization: `Bearer ${process.env.RAINDROP_WRITE_KEY}`,
        },
      }),
    }),
});
```

## Configure

Create a write key in the Raindrop dashboard and expose it as `RAINDROP_WRITE_KEY`. Raindrop's Vercel AI SDK integration picks up the AI SDK spans eve emits on every turn. See the [instrumentation guide](/docs/guides/instrumentation) for the trace hierarchy and the `recordInputs`/`recordOutputs` controls.
