Playwright In Sandbox

This is the primary Playwright skill for sandbox browser verification and deterministic end-to-end coverage.

Use it in two explicit modes:

1. Interactive Sandbox Mode as final browser verification after a task's implementation is in a plausibly correct state.
2. Deterministic E2E Mode before finishing a task when the changed flow should be protected by durable regression coverage.

This skill is intentionally generic. It should work for:

• task-level screenshot-driven verification after an agent has implemented UI work and needs browser proof
• formal Playwright E2E authoring or rewrite work in downstream application repos
• task flows where a final browser verification should happen before the task is considered complete

Do not use this skill for backend-only work, one-off page operations that do not justify browser automation, or broad failure storms before you understand the workflow inventory and root causes.
