Run Evals

Skill: Run Evals

Run the OpenWork UI evaluation flows against a real Electron app — either on a Daytona cloud sandbox or a local instance.

When to use

• User says "run evals on Daytona" or "run this flow on Daytona"
• User wants to verify a UI change end-to-end
• User wants to test the onboarding, session, or settings flows

Prerequisites

• daytona CLI installed and logged in (daytona login)
• Using the "Different AI" org (daytona organization use "Different AI")
• The .devcontainer/ files exist in the repo

Workflow

Step 1: Create sandbox (if not running)

Check for existing sandbox first:

daytona list

If no openwork-test sandbox, create one:

daytona create \
  --name openwork-test \
  --dockerfile .devcontainer/Dockerfile \
  --context .devcontainer/Dockerfile \
  --context .devcontainer/start-display.sh \
  --context .devcontainer/start-services.sh \
  --class large \
  --memory 8 \
  --auto-stop 60 \
  --public \
  --target us

Step 2: Start services

daytona exec openwork-test 'bash /workspace/.devcontainer/start-services.sh'

Wait for it to start (this runs in background, may timeout — that's OK).

Step 3: Verify

# Get CDP URL
daytona preview-url openwork-test -p 9825

Then use the browser tools to verify:

browser_list({ browser_url: "<CDP_URL>" })
→ should show "OpenWork" page target

Step 4: Create a workspace (if on welcome page)

If the app shows the Welcome page, create a workspace:

1. Create directory on sandbox:

   daytona exec openwork-test 'mkdir -p /workspace/hello'
   

2. Follow the workspace creation flow from evals/daytona-flows.md Flow 1:

   • Click "Get started" → "Local workspace"
   • Inject path via React fiber dispatch: { key: "selectedFolder", value: "/workspace/hello" }
   • Click "Create Workspace"
   • Wait 10s for opencode sidecar to boot

Step 5: Run the requested eval

Read the eval file from evals/ and execute each step using the browser tools.

For each step:

1. Execute the browser_evaluate / browser_click / browser_screenshot call
2. Verify the expected outcome
3. Report pass/fail

Key techniques

Clicking buttons:

browser_evaluate({ browser_url: URL, expression: "(function() { var btns = document.querySelectorAll('button'); for (var i = 0; i < btns.length; i++) { if (btns[i].textContent.indexOf('BUTTON_TEXT') !== -1) { btns[i].click(); return 'clicked'; } } return 'not found'; })()" })

Typing in Lexical editors:

browser_evaluate({ browser_url: URL, expression: "(function() { var e = document.querySelector('[contenteditable=true]'); e.focus(); document.execCommand('insertText', false, 'YOUR TEXT'); return 'typed'; })()" })

Injecting folder path (bypass native picker): Use the __reactFiber$ → CreateWorkspaceModal reducer dispatch with { key: "selectedFolder", value: "/path" }. Full code in evals/daytona-flows.md Flow 1 Step 5.

Checking page state:

browser_evaluate({ browser_url: URL, expression: "document.body.innerText.substring(0, 500)" })

Screenshots:

browser_screenshot({ browser_url: URL })

Teardown

daytona stop openwork-test    # preserves state for re-runs
daytona delete openwork-test  # full cleanup
