<Note>
  Before you begin, make sure you have:

  - A PandaProbe account. Sign up at [app.pandaprobe.com](https://app.pandaprobe.com).
  - At least one **trace** captured in your project. If you haven't set up tracing yet, follow the [Observability Quickstart](/get-started/quickstart) first.
  - For agent (session) evaluation: traces grouped under the same `session_id`.
</Note>

<Info>
  PandaProbe Cloud manages the evaluation LLM infrastructure for you. You do not need to bring your own LLM API key to run evaluations in PandaProbe Cloud.

## Run your first evaluation

The fastest way to evaluate is directly from the dashboard. You pick a trace (or session), choose a metric, and PandaProbe runs the evaluation in the background.

<Steps>
  <Step title="Open the Traces tab">
    In the PandaProbe dashboard, open the **Traces** tab. You should see the traces that were captured by the SDK.
  </Step>
  <Step title="Select traces to evaluate">
    Pick one or more traces, then click **Evaluate**. You can also open a single trace and click **Evaluate** from the detail view.
  </Step>
  <Step title="Choose a metric">
    Start with `task_completion` — a 2-stage LLM-as-judge metric that scores whether the agent accomplished the user's objective.

    <Tip>
      You can run multiple metrics in the same eval run. Each one produces an independent score attached to the trace.
    </Tip>
  </Step>
  <Step title="Submit the run">
    Click **Submit**. PandaProbe creates an eval run with status `PENDING` and dispatches the work to a background worker. The API responds with `202 Accepted`.
  </Step>
  <Step title="Review the score">
    Open the trace once the run completes. You should see a score with a numeric value, a pass/fail status, a human-readable reason, and structured metadata explaining how the score was produced.
  </Step>
</Steps>

## Try session evaluation

If you have traces grouped under a `session_id`, you can evaluate the entire agent lifecycle:

<Steps>
  <Step title="Open the Sessions tab">
    Open **Sessions** to view grouped agent lifecycles.
  </Step>
  <Step title="Select a session and click Evaluate">
    Choose one or more sessions and click **Evaluate**.
  </Step>
  <Step title="Pick a session metric">
    Start with `agent_reliability` — it surfaces worst-case failure risk across the session by aggregating trace-level signals (`confidence`, `coherence`, `tool_correctness`, `loop_detection`).
  </Step>
  <Step title="Submit and review">
    Submit the run. When it completes, the session detail page shows the aggregated score along with the trace-level signals that produced it.
  </Step>
</Steps>
