Triage Summary

Category: Feature (test coverage) · Severity: Medium

Problem

The onboarding/guided setup flow has no Playwright e2e test coverage, leaving it vulnerable to regressions (such as the one reported in #2287).

Recommended Approach

Create Playwright e2e tests in tests/playwright/src/ following the project's established Page Object Model patterns. The repo has good precedent from previously merged test PRs.

Key scenarios to cover:

• Fresh app launch triggers the guided setup
• Each step of the onboarding wizard can be navigated
• AI agent API key configuration completes successfully
• Setup completion lands the user on the main interface

Proposed Test Case

Test: Onboarding guided setup completes successfully

1. Launch app with no prior configuration (clean state)
2. Verify the onboarding screen is displayed
3. Navigate through each setup step
4. Enter AI agent configuration (API key)
5. Complete the setup wizard
6. Assert main application interface is displayed
7. Assert configured AI agent appears in provider list

Edge cases:
- Skipping optional steps
- Invalid API key error handling
- Back/forward navigation between steps
- Canceling setup midway
