test-playwright — Develop → Test → Fix (PDCA)

The job is not done when the code compiles. It is done when you have driven the live app as a user, found what's broken or clunky, and fixed it. This skill exists because agents implement a change, declare victory, and skip the Check and Act phases of PDCA. You will not skip them.

Plan = the change you just made. Do = it's already in the code. Check = drive the live app as a real user (this skill). Act = fix every pain point and error you find, in the same turn.

Before ANY browser action, read protocol-browser-anti-stall and apply every rule — especially Rule 0 (manual & headed, never scripted), plus the navigation guard, ≤3s waits, fresh browser_snapshot after every state change, max-4-attempts-per-goal, timeout budgets, tab discipline, and persisted auth (references/playwright-session-coordination.md).
