QA

Drive a website with a real browser, judge how well it does the thing the user asked about, and return a score from 1 (broken) to 5 (excellent) with evidence. The deliverable is a verdict, not a screenshot dump.

Inputs

From the user's invocation (the text after /qa, or their message):

• Target — a URL (https://…) or a local dev server (localhost:5173, :3000, "the app on 5173"). Required — if absent, ask for it before doing anything else.
• What to test (optional) — a flow or focus ("the signup", "search + filters"). If omitted, test the most obvious happy path and say so in the report.

Dependency: browser-harness (required — install it yourself)

This skill runs the test through browser-harness — a separate CLI you install once. It is not optional; QA must run on a real Browser Use cloud browser, never the user's local Chrome.

Before anything else, verify it's available:
