Triggers the ui-verifier subagent in a forked context.
Live browser verification specialist using playwright-mcp. Navigates a running
application, executes flows, and produces docs/test/UI_VERIFICATION_REPORT.md
with per-flow PASS/FAIL/WARN verdicts and descriptions of what was observed.
Works without vision: Uses accessibility tree snapshots (browser_snapshot())
as the primary verification signal — no vision-capable model required. Screenshots
are taken for visual record and described if vision is available.
Modes:
--smoke (default) — 5 min quick pass over main routes--use-cases — verify every P0 use case in USE_CASES.md--flow "description" — single flow end-to-end--regression — post-change check against last-known state
Requires: playwright-mcp registered (claude mcp list should show playwright).
If not registered, run ./install.sh or claude mcp add playwright -- npx -y @playwright/mcp@latest.
