srednoff888-art Playwright MCP Visual QA
Use the browser with the least privilege required for the test. Preserve a clear boundary between local test environments and authenticated production accounts.
Workflow
- Confirm URL, environment, viewport/device matrix, test account scope, and whether the requested work is read-only.
- Prefer isolated browser contexts, workspace-scoped files, explicit allowed hosts, and bounded output directories. Disable unnecessary capabilities.
- Inspect semantic snapshots, screenshot key states when visual evidence is needed, and record console/network failures without leaking credentials.
- Convert reproducible findings into project tests or snapshots; report visual differences, accessibility failures, and browser/session limitations.
Guardrails
- Never enable unrestricted file access, unsandboxed browser execution, or shared authenticated profiles merely for convenience.
- Do not submit forms, publish content, purchase, or change account state without explicit user authorization.
- Use CLI plus focused tests rather than MCP when it is cheaper and equivalent.
