Ce Test Browser

Automates end-to-end browser testing on pages touched by your PR or branch using agent-browser. It diffs your changes against main, maps affected files to routes (views, controllers, Stimulus controllers, components), then systematically opens each page, captures snapshots, and verifies elements render correctly. In pipeline mode it runs headless and auto-starts your dev server on a free port. In manual mode it asks if you want to watch the browser, which is genuinely useful when debugging flaky interactions. The route mapping is opinionated but covers Rails and Next.js patterns well. Good for catch-all smoke tests before merging, though you'll want real integration tests for complex flows.

Browser Test Skill

Run end-to-end browser tests on pages affected by a PR or branch using the best approved browser driver available in the active harness.

Done: the run ends by reporting what it found — either the summary, with every affected route marked Pass, Fail, or Skip and each Skip carrying its reason, or, when a preflight blocker stops testing before any route can be exercised, the blocker and what would clear it. Reaching neither, or dropping a route from the summary because nobody could reach it, is the failure this done condition exists to prevent.
