The Stratix VS Code extension brings evaluations into the editor. Run an eval from a code lens, inspect results in a side panel, and surface judge verdicts inline as you iterate on a prompt file.

## Install

From the VS Code marketplace, search "LayerLens Stratix" and install. The extension prompts for your API key on first activation.

## What it does

* **Run evaluations** from a code lens above any `.py` test or eval file
* **Inspect results** in a side panel — scores, per-row outputs, judge verdicts
* **Compare runs** — side-by-side
* **Show judge feedback inline** in prompt files
* **Open in browser** — jump from a result to the Premium UI

## Sign in

`Ctrl/Cmd + Shift + P` → **LayerLens: Sign in** → paste your API key. Keys are stored in the OS keychain via the VS Code Secrets API.

## Configuration

`settings.json`:

```json
{
 "layerlens.apiKey": "...",
 "layerlens.defaultOrg": "...",
 "layerlens.runEvalsOnSave": false
}
```

## Where to next

* [SDK quickstart](/2.-get-started/sdk.md)
* [Stratix Premium — Evaluations](/8.-evaluate-score-the-outputs/evaluations.md)
