Test: V2 workspace and model onboarding

Start with a build containing #336779, launch it with --transient --agents, enable the listed onboarding settings, and open New Session. Exercise the workspace and model tour with and without a workspace, including trust, keyboard, replay, and default-variation cases. Done means confirming the flow, focus, highlights, dismissal, and prompt submission behave as described, while reporting functional bugs or confusing copy.

Test the new two-step onboarding in the Agents Window. Focus on whether it behaves as expected and feels clear and smooth, rather than exhaustively testing every picker option.

Set up

1. Use a build containing #336779 (a PR build, or Insiders after it lands).
2. Launch with --transient for temporary user data and extensions, for example:

   code-insiders --transient --agents
   

   Complete sign-in/setup and wait for an agent to be available.
3. In this window's user settings, enable the V2 developer preview:

   {
     "onboarding.enabled": true,
     "onboarding.developerMode": {
       "sessions.onboarding.newSessionViewV2": true
     },
     "onboarding.developerModeVariations": {
       "sessions.onboarding.newSessionViewV2": "workspaceAndModel"
     }
   }
   

4. Close Settings and return to New Session. You may need to run Developer: Reload Window for the tour to appear. It runs once per window load; reload to replay. A new --transient launch starts fresh, so reapply the settings and sign in again if necessary.

Test

Try the flow both without a workspace and with a workspace already selected (select one, remain in New Session, and reload).

• The workspace picker is highlighted in both cases. It expands automatically only when no workspace is selected.
• You can press Next without choosing a workspace. On a replay, choose/change a workspace and verify the tour advances automatically after acceptance. Reselecting the same workspace should work too.
• There is no harness spotlight. The next step highlights the model picker without expanding it; you can still open it yourself and change models.
• Finish the tour and send a simple prompt, including a run without a workspace.

Try an untrusted local folder and leave its trust prompt open for a few seconds before accepting: the model step should still appear afterward. Declining trust must not incorrectly auto-advance.

Explore Back, Next, Done, Skip/Escape, and keyboard navigation. Check that highlights, picker popups, and focus behave sensibly and that no overlay blocks the composer after dismissal.

For a quick regression check, change the variation to "default" and reload: the workspace/harness/model tour should still work, with workspace selection optional. Report confusing copy or awkward transitions as well as functional bugs.
