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

Degree of freedom: MIXED — blast-radius and UX judgment [HIGH freedom]; session, anti-stall, and live re-test after each fix [LOW freedom — run exactly]. Driver is playwright-cli, never Playwright MCP.

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. Agents skip Check and Act — you will not.

Plan = the change you just made. Do = already in the code. Check = drive the live app (this skill). Act = fix every pain point in the same turn.

Read protocol-browser-anti-stall before any browser action — Rule 0 (manual & headed), navigation guard, ≤3s waits, fresh snapshot after every state change, max-4-attempts-per-goal, tab discipline, and persisted auth (references/playwright-session-coordination.md).
