# TypeSafe for Deno

Requires Sentry SDK version `11.1.0` or higher.

*Import name: `Sentry.typesafeIntegration`*

This integration is enabled by default when [tracing](https://docs.sentry.io/platforms/javascript/guides/deno/tracing.md) is enabled. To customize it, see [Modifying Default Integrations](https://docs.sentry.io/platforms/javascript/guides/deno/configuration/integrations.md#modifying-default-integrations).

The `typesafeIntegration` adds instrumentation for [`@typesafe-ai/sdk`](https://www.npmjs.com/package/@typesafe-ai/sdk) to capture [agent tracing](https://docs.sentry.io/platforms/javascript/guides/deno/agent-tracing.md) `gen_ai.evaluate` spans, recording model, token usage, latency, and (when enabled) evaluation inputs and answers.

If you call Jev through Vercel AI SDK's `experimental_evaluate()`, see the [Vercel AI integration](https://docs.sentry.io/platforms/javascript/guides/node/configuration/integrations/vercelai.md#trace-jev-evaluations) instead.

```javascript
Sentry.init({
  dsn: "https://<key>@o<orgId>.ingest.sentry.io/<projectId>",
  // Tracing must be enabled for agent tracing to work
  tracesSampleRate: 1.0,
  integrations: [Sentry.typesafeIntegration()],
});
```

On Deno, preload Sentry's import hook so the TypeSafe SDK can be instrumented:

```bash
deno run --allow-net --allow-env --allow-read --allow-sys --allow-write --preload=npm:@sentry/deno/import app.ts
```

## [Supported Operations](https://docs.sentry.io/platforms/javascript/guides/deno/configuration/integrations/typesafe.md#supported-operations)

Tracing support is added to `TypeSafeClient.systemOne()` calls to evaluate state against a set of questions using Jev. Each call creates a `gen_ai.evaluate` span. Recorded answers include probabilities and confidence values when returned by TypeSafe.

## [Supported Versions](https://docs.sentry.io/platforms/javascript/guides/deno/configuration/integrations/typesafe.md#supported-versions)

* `@typesafe-ai/sdk`: `>=0.5.0 <1`

## [Options](https://docs.sentry.io/platforms/javascript/guides/deno/configuration/integrations/typesafe.md#options)

Evaluation state and answers can contain sensitive data. Input and output recording are enabled by default. To disable them for TypeSafe, configure the integration explicitly:

```javascript
Sentry.init({
  dsn: "https://<key>@o<orgId>.ingest.sentry.io/<projectId>",
  tracesSampleRate: 1.0,
  integrations: [
    Sentry.typesafeIntegration({
      recordInputs: false,
      recordOutputs: false,
    }),
  ],
});
```

### [`recordInputs`](https://docs.sentry.io/platforms/javascript/guides/deno/configuration/integrations/typesafe.md#recordinputs)

*Type: `boolean` (optional)*

Records evaluation `state` and `questions`. Defaults to `dataCollection.genAI.inputs`, which is `true` by default.

### [`recordOutputs`](https://docs.sentry.io/platforms/javascript/guides/deno/configuration/integrations/typesafe.md#recordoutputs)

*Type: `boolean` (optional)*

Records evaluation `answers`. Defaults to `dataCollection.genAI.outputs`, which is `true` by default.
