browser-qa

name: browser-qa description: Use when validating or debugging a workflow in the embedded browser and you need a reproducible, evidence-first loop.

Browser QA

Use this skill when the task is browser validation, repro, regression checking, or investigation in the workspace-embedded browser.

Goals

• reproduce the issue with the fewest browser calls possible
• separate product failure from wait or locator failure
• capture only the evidence needed to explain the result

Repro Loop

1. State the exact starting page, tab, and account state you are testing.
2. Use the cheapest path that can reproduce the behavior.
3. After each page-changing step, use explicit waits rather than repeated broad state reads.
4. If a step fails, determine whether it is:
   • wrong target
   • stale target
   • missing wait
   • auth or session state
   • true product behavior
5. Capture evidence only after the failure is stable and reproducible.

Tool Discipline

• Prefer browser_act with wait_for over separate click then wait loops.
• Use browser_find when the target is known but compact state did not include it.
• Use browser_get_state detail=compact for orientation and detail=standard only when compact state is insufficient.
• If the page should expose the fact directly, inspect targeted custom-element attributes, data-* attributes, hrefs, or hydration data with a narrow read-only browser_evaluate before treating the fact as unavailable.
• Use browser_get_console, browser_get_errors, and browser_list_requests only after the cheaper orientation/action path failed or the issue is clearly runtime/network-related.
• Use browser_get_request only for one suspect request after browser_list_requests narrowed the field.
• Use browser_storage_get and browser_cookies_get to inspect auth or state flags before rerunning a long login flow.
• Use browser_storage_set and browser_cookies_set only for controlled state repair, not as a default shortcut.

Evidence Rules

• Capture screenshots only for visual ambiguity, layout issues, or user-visible confirmation.
• Read page text only when the task depends on the content itself.
• Treat page-local DOM evidence as primary evidence when the target page appears to render the needed fact; use third-party proxies or alternate sites only as fallback evidence.
• When a download is involved, prefer download_started and download_completed waits plus browser_list_downloads.
• Preserve the exact failing condition in the final report: target, wait, URL, and observed result.

Final Reporting

• Report whether the behavior reproduced.
• Report the smallest reliable repro path.
• Report whether the failure appears to be locator, timing, session state, or product behavior.
• Include only the minimum evidence needed to justify the conclusion.
